------ SPARK CEO -----
	 Like anything in our life, it starts so small then it gets bigger, bigger and bigger. Like
the calm before the storm, the dry seeds before the harvest or like your small baby you feed, it
grows. That was absolutely our DREAM.
	 Unfortunately, it was so complicated. You were not the only one in this field. Many and
many competitors were waiting you. You were not also qualified well and your team was not
the best. You were starting from nothing and your experience seemed to be zero. It looked like
you would never ever achieve your dream but you had a very precious thing the others didn’t.
It was ENERGY.
	 You let the dream begin. It began with work, power, hope and belief. Like small ants,
they are so weak but with unity and energy, they are much stronger than a lion. You never
thought about the barriers or the challenges that would block the way to your dream. You
only thought about the joy you would feel when you achieve it. You fell down many times but
immediately you came up, laughing at yourself and started again what you were doing. You
worked, worked and worked. And at last you achieved it.
“SPARK MAGAZINE”
	 For the first time and by the beginning of its second season, “AIChE Suez” is publishing
an online magazine specializes in the petroleum field just for serving the students in our faculty.
“Spark” is going to provide you with every single thing you have missed in your study field.
It will be the link that contacts you with anyone you want; a doctor, an engineer or even a
company.
	 Unlike any other magazine, “Spark” is going to be yours. If you have any research, news,
free article, creations or even any questions, you will be able to publish it through “Spark”. The
floor is open for all the students to write in “Spark” because “Spark” was mainly created just
for them. If you want to be a news reporter, an interviewer, a researcher or a writer, “Spark”
will help you achieve your dream. Within the issue, you will find questions from doctors and
from us. There will be very precious and excited rewards for the first 10 students with the right
answers.
	 You have a priceless product within your hand now. A great team has worked a lot to
deliver it to you. Many hours passed without sleeping just for you and many will pass again to
help you, as it’s our main target, our main message is “helping others”. Enjoy and get the most
benefit you can get from it and for any questions just contact us. Spark Magazine, It’s yours.

“Interview
	 1. Well, let’s be on track, can you
briefly tell us about yourself, your career,
and how did you start your professional
life?
	 I am Abeer Mahmoud
Shoaib. B.Sc of Petroleum
refining in 1996, M.Sc
of process integration in
2002, and PhD in Process
integration in 2008. Now,
I’m an associate professor in
chemical engineering. I had
a postdoctoral fellowship
for 6 months in 2011-
2012 at Process Integration
Centre (The University of
Manchester) Manchester,
UK. I’m interested in energy
conservation via process integration. In
addition, I’m interested in biofuel production
and published a reasonable number of papers
in this area of research.
	 2. How can you manage your time?
	 Well, It is a very important question!
Managing time is very complicated point
and very important. I do my best to give my
family the required care, then my
work. My work is divided into
lots of branches those I should
take into consideration. Helping
students is one of most important
points, since I feel them and
know well how they need our
help. My research is also another
branch that I must not ignore. In
addition, some administrative
services to my university I
should introduce. Unfortunately,
working in such a job needs to
ignoreyourpersonalrequirement
and focus on the needs of others
while any other job requires your interest in
specific time, but that job all your time you
are involved in your work duties. That’s too
hard! But I always do the priorities first.
>> Welcome Dr. Abeer. It will be a great honor to make this interview with you.
>> Thank you. You are welcome!

	 3. As you know,
AIChE SU SC represents a
teamwork group so can you
Give an example of a time
when you have worked on a
team?
	 Yeah! Working in
a team is very interesting.
Dividing the responsibilities
enable you to introduce the
best, when you do that, each
responsibility will be done
very well. One of the most
important point in working in
a team, is to like your friends
and respect performance even
it is not so good. This will
encourage them to introduce
better work and do their
best in such a responsibility
to be distinctive in that
work. In England, during
my postdoctoral fellowship,
we were working in a team
work in hydrogen integration
research.
	 4.Describethebiggest
challenge you have ever had
to face.
	 There were two big
challenges: The first was
when I have been put in a real
test. This was after taking
my M.Sc. It was my dream
to travel abroad to learn
more on a PhD study but
my family conditions were
not suitable for travelling
abroad. However, I have
tried to overcome such a
problem. I have contacted
the most popular researcher
in the world through emails
and depended on work
simulation. This was due to
the weakness of laboratory
possibilities in Egypt. I have
really learned a lot from such
an experience especially
from Professor Mahmoud El-
Halwagy, USA; and Professor
Dominic Foo, Nottingham
University who published
international publications
in an impacted journal. This
leads to a big lesson. Try to
overcome the challenge you
face and don’t be depressed.
May Allah offer better for
you. Do your best, you will
take the best with the help of
Allah. The second challenge
within these days is when I
have to choose between two
objects: my work needs and
my family needs. I have the
right to be the head of my
department. My department
needs all of my efforts and
all my professors tried to
persuade me to. This will take
much more time from me. On
the other hand, my children
are in a very critical stage.
My biggest daughter is in the
third year of secondary stage,
the other is in the third year of
preparatory stage, in addition
to their young brother. They
need my care in such a stage
more than any other stages.
I preferred my family needs
despite of the problems I face
as a result of such a decision.
However, I’m trying to
manage both work and home
needs and I did not leave
work.
	 5. Let’s talk on a
technical way, can you tell
us about the latest technique
you have heard about in the
petroleum field?
	 Crude oil hydrotreating
before any processing to face
the problems of heavy crude
oil and the trends toward
renewable energy.
	 6. Nowadays, as you
know we are suffering from
the problems of power
outages, so can you offer a
solution?And do you accept
generating electricity using
coke or not?
	 I think that there is
more than one point: The
first is rationalization of
consumption. This should
be done even if there is no
problem. Solar energy will
also solve part of the problem.
Regarding coke, I think that
we must direct research
for such a topic. How to
exploit coke taking into
consideration environmental
effects and try to maximize
benefits and minimize the
negative effects? That is a
very important optimization.
	 7. can you give some
advices to students of our
faculty?	
	 Do not focus on the
cons or negativities, Focus
on your aim. Studying in
such a faculty produced very
important engineers and
changed the life of more than
85%ofstudentsby180degree
to the positive. Love your
study here to facilitate your
life during the five years. Be
sure that: as you exert effort,
you will take good results.
	 8. What do you think
that really makes a good
engineer?
	 First, your expertise in
such a chapter with the aid of
Dr. Rehab polished you a lot.
Donotstopreading;searching
always for new trends will
6
SPARK|AIChESCSU
polish you by the novels and make you senior
in your position. Always like what you do,
do not let frustration overcome you, and be
always optimistic to facilitate your life. Be
sure that studying in that faculty will lead you
to a very important position in life. You are
really special.
	 9. If you are selected to make a new
project, which project will you choose?
And who is the staff member you are going
to choose to work with?
	 Biodiesel production and bio-jet fuel
production and I would work with Dr. Rehab
in this project.
	 10. What are your plans to develop
your career and our department?
	 First, we are trying to improve our lab
and we have already bought new, developed
devices and do our best to prepare a very
good refinery lab. We also trying to share in
financially supported projects to be a good
source for good work and increase the faculty
income.
	 11. As you know, last year was the
first season for our beloved AICHE SU SC,
so I would like to hear your comment about
it.
	 Firstly, I have to say that I respect
your work a lot. Try to make a session about
successful models of Petroleum engineers; not
to make a scientific lecture, but to introduce
their expertise in the way how studying in
that faculty changed their life. I think that a
high percent of students need to hear that to
push them toward success and to help them
overcome the difficulties they face. I think
that this is an important need for you. You are
very clever and good students; you only need
only a push to encourage you.
	 Finally, we are really happy to make
this interview with you Dr. and wish you a
great success and a happy life, Thank you.
	 It is a pleasure to me and really a good
chance to say what I need to transfer for my
beloved students. Wish you all the best.
Thanks Dr!

WASTE
HEAT
	 The demand for waste heat recovery
systems will continue to surge with the
growing requirement for energy efficiency
and rising environmental concerns regarding
industrial waste heat emissions. The waste
heat recovery systems offer energy savings
and ensure effective utilization of the waste
heat operations. These are the best solutions
to the concerns over increasing energy and
electricity prices. Technological improvement
is as a major opportunity for the waste heat
recovery systems market. The primary
consideration in the R&D effort of this market
lies in minimizing economic costs of waste
heat recovery technologies.
	 Waste heat recovery is the process
of capturing heat discarded by an existing
industrial process and using that heat for
other applications. Waste heat recovery
involves capturing and reusing the waste heat
from the industrial processes. The factors
driving waste heat recovery market are
increased growth in government regulatory
requirement, increasing concern towards
environmental protection, rising concern for
energy prices, and the reluctant use of waste
heat management. The future opportunities
for waste heat recovery systems are huge
potential in emerging economies such as
Asia-Pacific.
	 Waste heat recovery equipment finds
their usage in various industries for one or
more applications. Enhancing process heat
recovery efficiency provides significant and
immediate cost savings. The waste heat
recovery systems are used in various end-user
inindustriessuchaspetroleumrefining,heavy
metal production, cement, chemical refining
and other industries. The waste heat recovery
market in cement industry is anticipated to
grow at a highest CAGR of 9.32% due to the
high demand from Asia-Pacific region.

Stupid?!“
“He, who has a why to live for, can bear almost anyhow.”
Friedrich Nietzsche
	 >> Can you get it?
	 >> ................................!!
	 Let’s explain it in another way. If anyone
is going to some place that he doesn’t know, I
mean he doesn’t know the place itself not its
location, what will you say about him?! Yeah,
«Stupid!!» because he won’t reach any place!
	 If another one is going to a certain place,
he will reach there sooner or later and that’s
the point. You must know your destination.
Why do you live? What’s the purpose? What’s
your goal, your role and your mission in this
universe?
	 You must know that you haven’t been
created vainly. You have something to do here.
You must live a happy life and prepare for your
death at the same time.
	 This can occur only if you give some
attention to your religion. Religion is a perfect
system that can form your life. It tells you how
to worship your God, how to communicate
with people and how to be the good person
that can serve his country and his nation. You
must believe in your religion. You must be
sure that you are strong and you can complete
your mission. You aren’t weak.
	 Don’t say or repeat these lies again.
Climb a mountain, shout and say «I’m a
miracle. I’m an exception». Define your goal,
prepare your plan, pack your baggage and let
the dream begin.
	 I don’t know the dream that you have
but that dream, that you are holding in your
mind, is possible. The way to your dream
won’t be clear and on this way, you will suffer
from a lot of disappointment, failure and pain
and you may doubt yourself.
	 You may wonder, “Why this is
happening to me? I’m just trying to be a good
person.”, so you must know that hard times
will come but they haven’t come to stay! They
have come to pass.
	 You must believe in yourself. Someone’s
opinion of you doesn’t have to become your

reality but you don’t have to go through life being a victim. You must be strong and believe that
you can achieve your dream. Don’t give up your dream!
	 Finally, you have to know that it won’t be easy to stay on the right path so you must fight!
You will face many problems and barriers and you may fall so you must stay strong and be sure
that you can make it. You know your destination so keep moving towards it and you will reach
sooner or later. Don’t be weak or stupid and I promise you’ll reach!
Questions may help!
• What do you want to achieve in your life?
• Do you have (short, medium and long term) goals?
• Do you have a plan for your life?
• Can you define your priorities?
• Do you like your specialty?
• Do you read about your specialty?
• Do you read about other fields but your specialty?

“UGDC
Muhammad AbdullahA student at Faculty of Petroleum & Mining Engineering
	 The United Gas Derivatives Company (UGDC) was established in October 2001 as
an Egyptian joint stock company within the framework of the special free zones system.
	 The project is located in Port Said and it
relies on the natural gas produced from North
East Mediterranean fields (Al Temsah, Port
Fouad, Habi and Akhen) to extract natural
gas derivatives. It is designed to process
1100 million cubic feet per day to produce
300 thousand tons of LPG for the market,
280 thousand tons of Propane for export and
million barrel per year of condensates, and to
supply the olefin complex in the future with
Ethan/Propane mixture by 400 thousand tons
per year.
	 Production started up and the first
shipment of Propane was exported in
January 2005. The production of the plant till
November 2009 is as follows: 1476 thousand
tons of Propane for export, 1180 thousand
tons of LPG for local consumption and 7131
thousand barrels of condensates.
	 Theinvestmentcostisabout400million
dollars. LNG exporting projects executed in
Egypt are considered record breaking projects
worldwide. These projects will enable Egypt
to rank among the main LNG exporting
countries worldwide.
	 In order to finance these investment
11
SPARK|AIChESCSU
projects, the petroleum sector
followed an economic model
based on making benefit of
the available funds in the local
and international bunk place,
such that it does not impose
any burden on the public
treasure as follows: Providing
the fund of the capital cost
of these projects (up to 80 %
of the cost) through project
finance system, where the
economies of the project
as well as its feasibility
guarantee entirely repaying
the financing burden.
	 No doubt, Natural gas
liquefaction projects reflect
a deep vision towards the
future where the gas exporting
strategy is based on achieving
thebalancebetweenexporting
and the local consumption
requirements; to obtain a
return of foreign currency to
achieve the development, and
also to save the large percent
of the strategic reserves
for the future generations.
Year 2006 has witnessed the
implementation of various
activities & achievements for
UGDC.
	 The total revenues
during year 2006 reached
an amount of 223 million
dollars an equivalent to 1.3
billion Egyptian Pounds as
well as the net profit reached
an amount of 840 million
Egyptian pounds compared
with 420 million Egyptian
pounds during year 2005.
The total received amounts
of natural gases processed at
UGDC NGL plant reached
about 289 billion cubic feet
received from Temsah, Port
Fouad & Ha’apy fields. The
total of the LPG production
reached 161 thousand tons to
cover local market needs.
	 Condensate production
reached one million barrel
used at the petroleum refinery
in Suez in addition to the
Propane production of an
amount of 247 thousand
tons exported to the foreign
markets in Italy, France &
Portugal with revenues of
120 million dollars through
the exporting of a number of
twenty eight shipments The
return on investment rate
amounted to %36 with net
profits of 146 million dollars
considered as more than
double increase compared
with year 2005.
	 The value of the return
during the last two years
amounted to 219 million
dollars achieving a payback
of about %52 of the total
project costs leading to a
return per share of about
%44 during year 2006. Prior
to founding this company all
this wealth of natural gas was
used the worst using (fuel),
therefore it was necessary
for the establishment of the
company to take advantage of
this wealth.

“Distillation
EXTRACTIVE
with Ionic Liquids (ILs) as Solvents
Muhammad Behairy
A student at Faculty of Petroleum & Mining Engineering
		 Extractive distillation is widely
used method for separation of close BP,
low relative volatility, azeotropic mixtures.
Depending on adding liquid substance which
in turn interacts with mixture components.
This leads to an appreciable change in the
component’s activity coefficients (A number
expressing the ratio of a substance’s chemical
activity to its molar concentration). The
change in activity coefficients increases the
relative volatility gap which in turn achieves
feasible separation process.
	 The choice of the solvent is the
cornerstone of the process which determines
the feasibility of the method. The perfect
choice which achieves the appreciable increase
of relative volatility, energy consumption and
cares about total annual cost. Ionic liquid can
play this role as ionic liquids are salts in which
the ions are poorly coordinated, which results
in these solvents being liquid below 100°C, or
even at room temperature.
	 A comparison between ionic liquid
as 1-ethyl-3-methyl-imidazolium acetate
([EMIM][OAc]) and the conventional
process using (EG) ethylene glycol was
made. In extractive distillation process for the
separation of ethanol + water, and this was the
results. As shown the [EMIM][OAc] provides
a larger increase in relative volatility of the
mixture. As it is more hydrophilic, it attracts
the water making it less volatile.
	 In the history of separation processes, we used a lot of techniques to get the individual
component from mixtures as fractional distillation. Lots of techniques were proved to be
the best one to hit the target. On the other side, many techniques are not. As a result, not
all mixtures can be separated by fractional distillation. For instance, low relative volatility;
close boiling point (BP) mixtures including azeotropic mixtures are unfeasible to process in
ordinary methods. In order to make it feasible new techniques were developed as extractive
distillation with (IL) as solvents.
13
SPARK|AIChESCSU
	 From the data shown we
can conclude that, Extractive
Distillation Column (EDC)
uses lower energy with using
[EMIM][OAc], and achieves
more sufficient separation. As EG
is volatile, it evaporates in the
reboiler consuming energy, on the
other hand using [EMIM][OAc]
saves 8.2% of the energy required  
as it is non-volatile.
	 So we can conclude that
using extractive distillation with
ionic liquids as solvents can be a
suitable solution for the problem of
azeotropic and close BP mixtures.
Just we choose the suitable ionic
liquid. Several technologies were
analysed to solve the industrial
problems.As it is a dynamic battle,
when the alarm is on, science must
be involved. Science is stubborn,
science always has solutions.

“Technology
MEMBRANE
for CO2 Removal
Ibrahim Ragab HomosA student at Faculty of Petroleum & Mining Engineering
	 Traditional methods used to separate
CO2
from gas mixtures are pressure swing
adsorption, cryogenic distillation and the most
frequently used method amine absorption.
Also membrane processes are frequently used
for gas separation.
	 Energy requirements on the other hand
significantly benefit the use of membrane
technology over other technologies:
membrane technology uses 70-75 kWh per ton
of recovered CO2
compared to significantly
higher values for pressure swing adsorption
(160-180 kWh), cryogenic distillation (600-
800 kWh) or amine absorption (330-340
kWh), making membrane technology an
attractive alternative.
Fundamentals
	 Certain gases permeate or pass through
the membrane more easily than others. This
allows the more rapidly permeating (fast)
components to be collected in one stream and
the slower permeating (slow) components to
be collected in a second stream. In natural
gas treating, CO2
, hydrogen, helium, H2
S,
and water vapor are highly permeable
gases, sometimes characterized as “fast”
gas molecules that permeate to a greater
extent across the membrane to the lower
pressure side than do the “slower” gases (i.e.,
Hydrocarbons).
	 Next to its environmental impact, CO2
reduces the heating value of natural gas (CH4
)
in power plants and due to its acidic character, the presence of CO2
can lead to corrosion in
equipment and pipelines. This makes the removal of Co2
from natural gas of crucial importance.
15
SPARK|AIChESCSU
The driving force for
permeation is the difference
in partial pressure of a given
component between the feed
(high pressure) side and the
permeate (low pressure)
side of the membrane. The
greater the partial-pressure
difference, the greater the
driving force.
Theclassicalthermodynamics
tells us nothing about the rate
at which diffusion process
take place, but Fick’s law for
solution-diffusionmembranes
in rectangular co-ordinates is:
•	 Ji=(Si*Di*Pi)/l where,
•	 J» the flux of component;
(the molar flow of
component I through the
membrane per unit area of
membrane).
•	 S» solubility term.
•	 D» diffusion co-efficient.
•	 ΔP» partial pressure
difference across the
membrane.
•	 The term Pi/L is membrane
and operating conditions
dependent; ΔP is process
dependent; S, D depends
on temp. and pressure.
	 Selectivity α1-2, the
ratio of two permeabilities,
P1/P2. A selectivity α of 20
for CO2
/CH4
means that CO2
moves through the membrane
20 times faster than does
methane.
	 The coefficient   of
permeability, K, is a function
of both the solubility and
the diffusivity of the gas in
the polymer matrix. Several
mathematical models are
available that derive the
permeability coefficients
	Next to the
permeability, the main factor
to describe the performance of
a membrane is its separation
ability, called the selectivity
α. The ideal selectivity using
pure gases is given by the
ratio of the permeability
coefficients (Pi), which is,
when assuming solution-
diffusion to occur, composed
of a diffusivity selectivity
term (DCO2
/DCH4
) and a
solubility selectivity term
(SCO2
/SCH4
):
	 For gas mixtures the
feed composition has to be
taken into account as well
and the membrane selectivity
is expressed as:
Where Yi is the concentration
of component i in the
permeate stream and Xi is the
concentration of component i
in the feed.
	 Selectivity refers to
the ratio of the permeation
rates of a fast gas (CO2
) and
a slow gas (Methane or other
Hydrocarbon). The selectivity
of CO2
to methane determines
theefficiencyoftheseparation
and the methane recovery.

This table shows typical membrane materials that can be used to separate the impurities from natural gas
16
SPARK|AIChESCSU
	 Membrane uses include dehydration, fuel gas conditioning and bulk CO2
removal which
is the most important application. The membrane market share is about 2%, essentially all for
CO2
removal. This fraction will likely increase because other applications of membranes in the
natural gas processing industry are under development.
	 Many different types of membranes have been developed for industrial separation, but
for CO2
removal, the industry standard is presently cellulose acetate.
	 Membrane composition:
	 A thin layer (0.1-0.5) ή m of cellulose acetate is on top of thicker layer of a porous
support material. Permeate compounds dissolve into the membrane, diffuse across it, then
travel through the inactive support material. The membranes are thin to maximize mass
transfer, minimize surface area and cost. The support layer is necessary to support the needed
mechanical strength.
	 Commercial membrane configuration are either hollow fiber elements or flat sheets
wrapped into spirally wound elements.
SPIRAL WOUND MEMBRANE STRUCTURE
	
A membrane sheet has two layers:
a relatively thick microporous layer that is
in contact with the cloth support and a thin
active layer on top of the microporous layer.
The membrane sheets are separated by a
permeate spacer and glued shut at three ends
to form an envelope or leaf. Many of these
leaves, separated by feed spacer are wrapped
around the permeate tube, with the open end
of the leaves facing the tube.
	 Feed gas travels along the feed spacer,
the permeating species diffuse through the
membrane and down the permeate spacer into
the permeate tube, the residue gas exits at the
end and the gas flow is cross flow. The spiral
configuration is inherently more resistant
than the hollow fiber membranes to trace
components that would alter the polymer
permeability. It also allows a wider range of
membrane material to be used. The hollow
fiber membrane is
cheaper than the spiral one.
	 Each membrane unit contains a
pretreatment unit and membrane skids. Each
pretreatment unit consists of a filter coalescer,
a guard bed, and a particle filter. Each
membrane skid consists of membrane tubes
containing membrane elements.

Petroleum and Technology
(Apache Corp uses new technology in the Gulf of Mexico)
Apache Corp and some smaller independent companies are
using seismic surveying and horizontal drilling to find hidden
reserves in the Gulf of Mexico. Horizontal drilling allows
companies to set up miles-long pipes through a single rock
formation and can deliver up to 20 times the production of wells
tapped by vertical drills. The technology is not entirely new,
but when combined with recent advances in seismic tools, the
biggest advantage of horizontal drilling is its ability to identify
the maximum amount of oil and gas in rock formations. New
seismic tools use sound waves that allow drillers to “see” oil
and gas trapped in rocks through high-resolution 3D images.
Total proved reserves in the Gulf of Mexico are about 4.9
billion barrels of oil equivalent, according to the U.S. Energy
Information Administration.
Petroleum and the Environment
(Nigeria Oil Pollution)
Nigeria,Africa’s largest oil producer, pumping out roughly two
million barrels per day, and Shell have done almost nothing to
ease oil pollution in the Ogoniland area of the Niger Delta. A
United Nations Environment Programme report said the area
may require the world’s biggest-ever clean-up and called on
Shell and the Nigerian government to contribute $1 billion
Petroleum and the Economy
-Oil prices rise in Asia:
Oil prices rose in Asia on August 5th due to fears of supply
disruptions in the Middle East. Analysts have said the violence
in crude producer Libya, where at least 124 people have died
since July 13, threatens efforts to restore oil production in the
North African country. Moreover, militants have seized two
small oilfields in Iraq, the second biggest producer in OPEC.
Petroleum and Politics
(Russia & Iran sign historic oil deal)
Russia signed a historic $20 billion oil deal with Iran. Russia
would buy up to 500,000 barrels a day (one third of Iranian
oil exports) in exchange for Russian equipment and goods.
Notably, the White House has previously said that talks
between Russia and Iran were a matter of “serious concern”.

August 6th. During the tour,
the President of the General
Petroleum Company said
that they plan to drill 14 new
wells, onshore and offshore
in 2014/2015, increasing the
company’s crude production
to 45000 barrels per day.
Furthermore, the President of
Agiba Petroleum Company
said the company managed to
produce about 64000 barrels
per day last month, and that
they plan to drill 55 new

Noteworthy, the chapter had its second mass-media appearance this year in July. Chapter
President Kareem El-Maghloub, Marketing Coordinator Kareem Salah, and Publicity Head
Nada Salah had an interesting one-hour interview with The Educational Channel Radio.
The three representatives had a fruitful talk about the faculty’s problems, the chapter’s
campus and off-campus activities (most importantly, the Energy Campaign), their contact
with the Ministry of Higher Education, and much more.
During this summer vacation, AIChE has, undoubtedly,
established itself as one of the most impressive student chapters
in Suez University. Seeing a notable number of newly accepted
members and a handful of successful Facebook events, it is
safe to say that AIChE members have had an eventful summer.
Also, the chapter used social networking to reach out for the
students via Facebook events. One of these that stood out was
named “DrawYour Future and ChooseYour Career”. Basically,
the chapter’s official Facebook page wrote detailed posts that
explained each college department thoroughly, helping First
Year students make their decision and know more about their
Another remarkable
Facebook event was
called “Lead Your
Dream”; inspired by the
chapter’s new slogan.
Students were asked to
suggest creative ideas
to make our campus a
better place, andAIChE,
in return, promised to
help turn their best idea
into reality.
In other news, Nada Salah, Head of Publicity at AIChE Suez,
said that her committee has recently gained about 10 new
members. “We’ve held various meetings, and we’ve created a
workshop to teach new members how to promote fieldtrips”,
she added.
Nada said that the chapter has provided the students with about
60 training opportunities for the first time in the faculty’s
history.
Last but not least, I
was told that we will
be expecting a lot
from AIChE in the
upcoming 2014/2015
academic year. “We’ve
been working on a
lot of projects. Lots
of paperwork,” said
Secretary Aya Ahmed,
“But you won’t be
disappointed”.

  • 3. 3 SPARK|AIChESCSU Muhammad Mansour ------ SPARK CEO ----- Like anything in our life, it starts so small then it gets bigger, bigger and bigger. Like the calm before the storm, the dry seeds before the harvest or like your small baby you feed, it grows. That was absolutely our DREAM. Unfortunately, it was so complicated. You were not the only one in this field. Many and many competitors were waiting you. You were not also qualified well and your team was not the best. You were starting from nothing and your experience seemed to be zero. It looked like you would never ever achieve your dream but you had a very precious thing the others didn’t. It was ENERGY. You let the dream begin. It began with work, power, hope and belief. Like small ants, they are so weak but with unity and energy, they are much stronger than a lion. You never thought about the barriers or the challenges that would block the way to your dream. You only thought about the joy you would feel when you achieve it. You fell down many times but immediately you came up, laughing at yourself and started again what you were doing. You worked, worked and worked. And at last you achieved it. “SPARK MAGAZINE” For the first time and by the beginning of its second season, “AIChE Suez” is publishing an online magazine specializes in the petroleum field just for serving the students in our faculty. “Spark” is going to provide you with every single thing you have missed in your study field. It will be the link that contacts you with anyone you want; a doctor, an engineer or even a company. Unlike any other magazine, “Spark” is going to be yours. If you have any research, news, free article, creations or even any questions, you will be able to publish it through “Spark”. The floor is open for all the students to write in “Spark” because “Spark” was mainly created just for them. If you want to be a news reporter, an interviewer, a researcher or a writer, “Spark” will help you achieve your dream. Within the issue, you will find questions from doctors and from us. There will be very precious and excited rewards for the first 10 students with the right answers. You have a priceless product within your hand now. A great team has worked a lot to deliver it to you. Many hours passed without sleeping just for you and many will pass again to help you, as it’s our main target, our main message is “helping others”. Enjoy and get the most benefit you can get from it and for any questions just contact us. Spark Magazine, It’s yours. From A Dream To Reality
  • 4. 4 SPARK|AIChESCSU “Interview 1. Well, let’s be on track, can you briefly tell us about yourself, your career, and how did you start your professional life? I am Abeer Mahmoud Shoaib. B.Sc of Petroleum refining in 1996, M.Sc of process integration in 2002, and PhD in Process integration in 2008. Now, I’m an associate professor in chemical engineering. I had a postdoctoral fellowship for 6 months in 2011- 2012 at Process Integration Centre (The University of Manchester) Manchester, UK. I’m interested in energy conservation via process integration. In addition, I’m interested in biofuel production and published a reasonable number of papers in this area of research. 2. How can you manage your time? Well, It is a very important question! Managing time is very complicated point and very important. I do my best to give my family the required care, then my work. My work is divided into lots of branches those I should take into consideration. Helping students is one of most important points, since I feel them and know well how they need our help. My research is also another branch that I must not ignore. In addition, some administrative services to my university I should introduce. Unfortunately, working in such a job needs to ignoreyourpersonalrequirement and focus on the needs of others while any other job requires your interest in specific time, but that job all your time you are involved in your work duties. That’s too hard! But I always do the priorities first. >> Welcome Dr. Abeer. It will be a great honor to make this interview with you. >> Thank you. You are welcome! MuhammadAbdElBasset A student at Faculty of Petroleum & Mining Engineering Dr. Abeer Sho’aib AProfessoratFacultyofPetroleum and Mining Engineering
  • 5. 5 SPARK|AIChESCSU 3. As you know, AIChE SU SC represents a teamwork group so can you Give an example of a time when you have worked on a team? Yeah! Working in a team is very interesting. Dividing the responsibilities enable you to introduce the best, when you do that, each responsibility will be done very well. One of the most important point in working in a team, is to like your friends and respect performance even it is not so good. This will encourage them to introduce better work and do their best in such a responsibility to be distinctive in that work. In England, during my postdoctoral fellowship, we were working in a team work in hydrogen integration research. 4.Describethebiggest challenge you have ever had to face. There were two big challenges: The first was when I have been put in a real test. This was after taking my M.Sc. It was my dream to travel abroad to learn more on a PhD study but my family conditions were not suitable for travelling abroad. However, I have tried to overcome such a problem. I have contacted the most popular researcher in the world through emails and depended on work simulation. This was due to the weakness of laboratory possibilities in Egypt. I have really learned a lot from such an experience especially from Professor Mahmoud El- Halwagy, USA; and Professor Dominic Foo, Nottingham University who published international publications in an impacted journal. This leads to a big lesson. Try to overcome the challenge you face and don’t be depressed. May Allah offer better for you. Do your best, you will take the best with the help of Allah. The second challenge within these days is when I have to choose between two objects: my work needs and my family needs. I have the right to be the head of my department. My department needs all of my efforts and all my professors tried to persuade me to. This will take much more time from me. On the other hand, my children are in a very critical stage. My biggest daughter is in the third year of secondary stage, the other is in the third year of preparatory stage, in addition to their young brother. They need my care in such a stage more than any other stages. I preferred my family needs despite of the problems I face as a result of such a decision. However, I’m trying to manage both work and home needs and I did not leave work. 5. Let’s talk on a technical way, can you tell us about the latest technique you have heard about in the petroleum field? Crude oil hydrotreating before any processing to face the problems of heavy crude oil and the trends toward renewable energy. 6. Nowadays, as you know we are suffering from the problems of power outages, so can you offer a solution?And do you accept generating electricity using coke or not? I think that there is more than one point: The first is rationalization of consumption. This should be done even if there is no problem. Solar energy will also solve part of the problem. Regarding coke, I think that we must direct research for such a topic. How to exploit coke taking into consideration environmental effects and try to maximize benefits and minimize the negative effects? That is a very important optimization. 7. can you give some advices to students of our faculty? Do not focus on the cons or negativities, Focus on your aim. Studying in such a faculty produced very important engineers and changed the life of more than 85%ofstudentsby180degree to the positive. Love your study here to facilitate your life during the five years. Be sure that: as you exert effort, you will take good results. 8. What do you think that really makes a good engineer? First, your expertise in such a chapter with the aid of Dr. Rehab polished you a lot. Donotstopreading;searching always for new trends will
  • 6. 6 SPARK|AIChESCSU polish you by the novels and make you senior in your position. Always like what you do, do not let frustration overcome you, and be always optimistic to facilitate your life. Be sure that studying in that faculty will lead you to a very important position in life. You are really special. 9. If you are selected to make a new project, which project will you choose? And who is the staff member you are going to choose to work with? Biodiesel production and bio-jet fuel production and I would work with Dr. Rehab in this project. 10. What are your plans to develop your career and our department? First, we are trying to improve our lab and we have already bought new, developed devices and do our best to prepare a very good refinery lab. We also trying to share in financially supported projects to be a good source for good work and increase the faculty income. 11. As you know, last year was the first season for our beloved AICHE SU SC, so I would like to hear your comment about it. Firstly, I have to say that I respect your work a lot. Try to make a session about successful models of Petroleum engineers; not to make a scientific lecture, but to introduce their expertise in the way how studying in that faculty changed their life. I think that a high percent of students need to hear that to push them toward success and to help them overcome the difficulties they face. I think that this is an important need for you. You are very clever and good students; you only need only a push to encourage you. Finally, we are really happy to make this interview with you Dr. and wish you a great success and a happy life, Thank you. It is a pleasure to me and really a good chance to say what I need to transfer for my beloved students. Wish you all the best. Thanks Dr!
  • 7. 7 SPARK|AIChESCSU “ Recovery Mahmoud M. Harb A student at Faculty of Petroleum & Mining Engineering WASTE HEAT The demand for waste heat recovery systems will continue to surge with the growing requirement for energy efficiency and rising environmental concerns regarding industrial waste heat emissions. The waste heat recovery systems offer energy savings and ensure effective utilization of the waste heat operations. These are the best solutions to the concerns over increasing energy and electricity prices. Technological improvement is as a major opportunity for the waste heat recovery systems market. The primary consideration in the R&D effort of this market lies in minimizing economic costs of waste heat recovery technologies. Waste heat recovery is the process of capturing heat discarded by an existing industrial process and using that heat for other applications. Waste heat recovery involves capturing and reusing the waste heat from the industrial processes. The factors driving waste heat recovery market are increased growth in government regulatory requirement, increasing concern towards environmental protection, rising concern for energy prices, and the reluctant use of waste heat management. The future opportunities for waste heat recovery systems are huge potential in emerging economies such as Asia-Pacific. Waste heat recovery equipment finds their usage in various industries for one or more applications. Enhancing process heat recovery efficiency provides significant and immediate cost savings. The waste heat recovery systems are used in various end-user inindustriessuchaspetroleumrefining,heavy metal production, cement, chemical refining and other industries. The waste heat recovery market in cement industry is anticipated to grow at a highest CAGR of 9.32% due to the high demand from Asia-Pacific region.

Yeah, «Stupid!!» because he won’t reach any place! If another one is going to a certain place, he will reach there sooner or later and that’s the point. You must know your destination. Why do you live? What’s the purpose? What’s your goal, your role and your mission in this universe? You must know that you haven’t been created vainly. You have something to do here. You must live a happy life and prepare for your death at the same time. This can occur only if you give some attention to your religion. Religion is a perfect system that can form your life. It tells you how to worship your God, how to communicate with people and how to be the good person that can serve his country and his nation. You must believe in your religion. You must be sure that you are strong and you can complete your mission. You aren’t weak. Don’t say or repeat these lies again. Climb a mountain, shout and say «I’m a miracle. I’m an exception». Define your goal, prepare your plan, pack your baggage and let the dream begin. I don’t know the dream that you have but that dream, that you are holding in your mind, is possible. The way to your dream won’t be clear and on this way, you will suffer from a lot of disappointment, failure and pain and you may doubt yourself. You may wonder, “Why this is happening to me? I’m just trying to be a good person.”, so you must know that hard times will come but they haven’t come to stay! They have come to pass. You must believe in yourself.

  • 11. 11 SPARK|AIChESCSU projects, the petroleum sector followed an economic model based on making benefit of the available funds in the local and international bunk place, such that it does not impose any burden on the public treasure as follows: Providing the fund of the capital cost of these projects (up to 80 % of the cost) through project finance system, where the economies of the project as well as its feasibility guarantee entirely repaying the financing burden. No doubt, Natural gas liquefaction projects reflect a deep vision towards the future where the gas exporting strategy is based on achieving thebalancebetweenexporting and the local consumption requirements; to obtain a return of foreign currency to achieve the development, and also to save the large percent of the strategic reserves for the future generations. Year 2006 has witnessed the implementation of various activities & achievements for UGDC. The total revenues during year 2006 reached an amount of 223 million dollars an equivalent to 1.3 billion Egyptian Pounds as well as the net profit reached an amount of 840 million Egyptian pounds compared with 420 million Egyptian pounds during year 2005. The total received amounts of natural gases processed at UGDC NGL plant reached about 289 billion cubic feet received from Temsah, Port Fouad & Ha’apy fields. The total of the LPG production reached 161 thousand tons to cover local market needs. Condensate production reached one million barrel used at the petroleum refinery in Suez in addition to the Propane production of an amount of 247 thousand tons exported to the foreign markets in Italy, France & Portugal with revenues of 120 million dollars through the exporting of a number of twenty eight shipments The return on investment rate amounted to %36 with net profits of 146 million dollars considered as more than double increase compared with year 2005. The value of the return during the last two years amounted to 219 million dollars achieving a payback of about %52 of the total project costs leading to a return per share of about %44 during year 2006. Prior to founding this company all this wealth of natural gas was used the worst using (fuel), therefore it was necessary for the establishment of the company to take advantage of this wealth.
  • 12. 12 SPARK|AIChESCSU “Distillation EXTRACTIVE with Ionic Liquids (ILs) as Solvents Muhammad Behairy A student at Faculty of Petroleum & Mining Engineering Extractive distillation is widely used method for separation of close BP, low relative volatility, azeotropic mixtures. Depending on adding liquid substance which in turn interacts with mixture components. This leads to an appreciable change in the component’s activity coefficients (A number expressing the ratio of a substance’s chemical activity to its molar concentration). The change in activity coefficients increases the relative volatility gap which in turn achieves feasible separation process. The choice of the solvent is the cornerstone of the process which determines the feasibility of the method. The perfect choice which achieves the appreciable increase of relative volatility, energy consumption and cares about total annual cost. Ionic liquid can play this role as ionic liquids are salts in which the ions are poorly coordinated, which results in these solvents being liquid below 100°C, or even at room temperature. A comparison between ionic liquid as 1-ethyl-3-methyl-imidazolium acetate ([EMIM][OAc]) and the conventional process using (EG) ethylene glycol was made. In extractive distillation process for the separation of ethanol + water, and this was the results. As shown the [EMIM][OAc] provides a larger increase in relative volatility of the mixture. As it is more hydrophilic, it attracts the water making it less volatile. In the history of separation processes, we used a lot of techniques to get the individual component from mixtures as fractional distillation. Lots of techniques were proved to be the best one to hit the target. On the other side, many techniques are not. As a result, not all mixtures can be separated by fractional distillation. For instance, low relative volatility; close boiling point (BP) mixtures including azeotropic mixtures are unfeasible to process in ordinary methods. In order to make it feasible new techniques were developed as extractive distillation with (IL) as solvents.
  • 13. 13 SPARK|AIChESCSU From the data shown we can conclude that, Extractive Distillation Column (EDC) uses lower energy with using [EMIM][OAc], and achieves more sufficient separation. As EG is volatile, it evaporates in the reboiler consuming energy, on the other hand using [EMIM][OAc] saves 8.2% of the energy required as it is non-volatile. So we can conclude that using extractive distillation with ionic liquids as solvents can be a suitable solution for the problem of azeotropic and close BP mixtures. Just we choose the suitable ionic liquid. Several technologies were analysed to solve the industrial problems.As it is a dynamic battle, when the alarm is on, science must be involved. Science is stubborn, science always has solutions.

  • 14. 14 SPARK|AIChESCSU “Technology MEMBRANE for CO2 Removal Ibrahim Ragab HomosA student at Faculty of Petroleum & Mining Engineering Traditional methods used to separate CO2 from gas mixtures are pressure swing adsorption, cryogenic distillation and the most frequently used method amine absorption. Also membrane processes are frequently used for gas separation. Energy requirements on the other hand significantly benefit the use of membrane technology over other technologies: membrane technology uses 70-75 kWh per ton of recovered CO2 compared to significantly higher values for pressure swing adsorption (160-180 kWh), cryogenic distillation (600- 800 kWh) or amine absorption (330-340 kWh), making membrane technology an attractive alternative. Fundamentals Certain gases permeate or pass through the membrane more easily than others. This allows the more rapidly permeating (fast) components to be collected in one stream and the slower permeating (slow) components to be collected in a second stream. In natural gas treating, CO2 , hydrogen, helium, H2 S, and water vapor are highly permeable gases, sometimes characterized as “fast” gas molecules that permeate to a greater extent across the membrane to the lower pressure side than do the “slower” gases (i.e., Hydrocarbons). Next to its environmental impact, CO2 reduces the heating value of natural gas (CH4 ) in power plants and due to its acidic character, the presence of CO2 can lead to corrosion in equipment and pipelines. This makes the removal of Co2 from natural gas of crucial importance.
  • 15. 15 SPARK|AIChESCSU The driving force for permeation is the difference in partial pressure of a given component between the feed (high pressure) side and the permeate (low pressure) side of the membrane. The greater the partial-pressure difference, the greater the driving force. Theclassicalthermodynamics tells us nothing about the rate at which diffusion process take place, but Fick’s law for solution-diffusionmembranes in rectangular co-ordinates is: • Ji=(Si*Di*Pi)/l where, • J» the flux of component; (the molar flow of component I through the membrane per unit area of membrane). • S» solubility term. • D» diffusion co-efficient. • ΔP» partial pressure difference across the membrane. • The term Pi/L is membrane and operating conditions dependent; ΔP is process dependent; S, D depends on temp. and pressure. Selectivity α1-2, the ratio of two permeabilities, P1/P2. A selectivity α of 20 for CO2 /CH4 means that CO2 moves through the membrane 20 times faster than does methane. The coefficient of permeability, K, is a function of both the solubility and the diffusivity of the gas in the polymer matrix. Several mathematical models are available that derive the permeability coefficients Next to the permeability, the main factor to describe the performance of a membrane is its separation ability, called the selectivity α. The ideal selectivity using pure gases is given by the ratio of the permeability coefficients (Pi), which is, when assuming solution- diffusion to occur, composed of a diffusivity selectivity term (DCO2 /DCH4 ) and a solubility selectivity term (SCO2 /SCH4 ): For gas mixtures the feed composition has to be taken into account as well and the membrane selectivity is expressed as: Where Yi is the concentration of component i in the permeate stream and Xi is the concentration of component i in the feed. Selectivity refers to the ratio of the permeation rates of a fast gas (CO2 ) and a slow gas (Methane or other Hydrocarbon). The selectivity of CO2 to methane determines theefficiencyoftheseparation and the methane recovery. αideal = ------------------- = ------------------- . ------------------- PCO2 DCO2 SCO2 PCH4 DCH4 SCH4 αideal = ------------------------------------------------------ YCO2 / YCH4 XCO2 / XCH4 Equation: where: ῡ: Volume of permeated gas,scf/hr.

  • 16. 16 SPARK|AIChESCSU Membrane uses include dehydration, fuel gas conditioning and bulk CO2 removal which is the most important application. The membrane market share is about 2%, essentially all for CO2 removal. This fraction will likely increase because other applications of membranes in the natural gas processing industry are under development. Many different types of membranes have been developed for industrial separation, but for CO2 removal, the industry standard is presently cellulose acetate. Membrane composition: A thin layer (0.1-0.5) ή m of cellulose acetate is on top of thicker layer of a porous support material. Permeate compounds dissolve into the membrane, diffuse across it, then travel through the inactive support material. The membranes are thin to maximize mass transfer, minimize surface area and cost. The support layer is necessary to support the needed mechanical strength. Commercial membrane configuration are either hollow fiber elements or flat sheets wrapped into spirally wound elements. SPIRAL WOUND MEMBRANE STRUCTURE A membrane sheet has two layers: a relatively thick microporous layer that is in contact with the cloth support and a thin active layer on top of the microporous layer. The membrane sheets are separated by a permeate spacer and glued shut at three ends to form an envelope or leaf. Many of these leaves, separated by feed spacer are wrapped around the permeate tube, with the open end of the leaves facing the tube. Feed gas travels along the feed spacer, the permeating species diffuse through the membrane and down the permeate spacer into the permeate tube, the residue gas exits at the end and the gas flow is cross flow. The spiral configuration is inherently more resistant than the hollow fiber membranes to trace components that would alter the polymer permeability. It also allows a wider range of membrane material to be used. The hollow fiber membrane is cheaper than the spiral one. Each membrane unit contains a pretreatment unit and membrane skids. Each pretreatment unit consists of a filter coalescer, a guard bed, and a particle filter. Each membrane skid consists of membrane tubes containing membrane elements.

Horizontal drilling allows companies to set up miles-long pipes through a single rock formation and can deliver up to 20 times the production of wells tapped by vertical drills. The technology is not entirely new, but when combined with recent advances in seismic tools, the biggest advantage of horizontal drilling is its ability to identify the maximum amount of oil and gas in rock formations. New seismic tools use sound waves that allow drillers to “see” oil and gas trapped in rocks through high-resolution 3D images. Total proved reserves in the Gulf of Mexico are about 4.9 billion barrels of oil equivalent, according to the U.S. Energy Information Administration. Petroleum and the Environment (Nigeria Oil Pollution) Nigeria,Africa’s largest oil producer, pumping out roughly two million barrels per day, and Shell have done almost nothing to ease oil pollution in the Ogoniland area of the Niger Delta. A United Nations Environment Programme report said the area may require the world’s biggest-ever clean-up and called on Shell and the Nigerian government to contribute $1 billion Petroleum and the Economy -Oil prices rise in Asia: Oil prices rose in Asia on August 5th due to fears of supply disruptions in the Middle East. Analysts have said the violence in crude producer Libya, where at least 124 people have died since July 13, threatens efforts to restore oil production in the North African country. Moreover, militants have seized two small oilfields in Iraq, the second biggest producer in OPEC. Petroleum and Politics (Russia & Iran sign historic oil deal) Russia signed a historic $20 billion oil deal with Iran. Russia would buy up to 500,000 barrels a day (one third of Iranian oil exports) in exchange for Russian equipment and goods. Notably, the White House has previously said that talks between Russia and Iran were a matter of “serious concern”. Local Petroleum News (Egyptian Minister of Petroleum visits fields) Eng. Sherif Ismail, Minister of Petroleum and Mineral Resources, finished visiting variousoilfieldsintheEastern DesertandtheGulfofSuezon August 6th. During the tour, the President of the General Petroleum Company said that they plan to drill 14 new wells, onshore and offshore in 2014/2015, increasing the company’s crude production to 45000 barrels per day. Furthermore, the President of Agiba Petroleum Company said the company managed to produce about 64000 barrels per day last month, and that they plan to drill 55 new wells in 2015. In other news, the ministry’s spokesman, Hamdi Abdelaziz, has denied the rumours about domestic gas cylinders’prices going up. PETROL news
  • 18. 18 SPARK|AIChESCSU Noteworthy, the chapter had its second mass-media appearance this year in July. Chapter President Kareem El-Maghloub, Marketing Coordinator Kareem Salah, and Publicity Head Nada Salah had an interesting one-hour interview with The Educational Channel Radio. The three representatives had a fruitful talk about the faculty’s problems, the chapter’s campus and off-campus activities (most importantly, the Energy Campaign), their contact with the Ministry of Higher Education, and much more. During this summer vacation, AIChE has, undoubtedly, established itself as one of the most impressive student chapters in Suez University. Seeing a notable number of newly accepted members and a handful of successful Facebook events, it is safe to say that AIChE members have had an eventful summer. Also, the chapter used social networking to reach out for the students via Facebook events. One of these that stood out was named “DrawYour Future and ChooseYour Career”. Basically, the chapter’s official Facebook page wrote detailed posts that explained each college department thoroughly, helping First Year students make their decision and know more about their Another remarkable Facebook event was called “Lead Your Dream”; inspired by the chapter’s new slogan. Students were asked to suggest creative ideas to make our campus a better place, andAIChE, in return, promised to help turn their best idea into reality. In other news, Nada Salah, Head of Publicity at AIChE Suez, said that her committee has recently gained about 10 new members. “We’ve held various meetings, and we’ve created a workshop to teach new members how to promote fieldtrips”, she added. Nada said that the chapter has provided the students with about 60 training opportunities for the first time in the faculty’s history. Last but not least, I was told that we will be expecting a lot from AIChE in the upcoming 2014/2015 academic year. “We’ve been working on a lot of projects. Lots of paperwork,” said Secretary Aya Ahmed, “But you won’t be disappointed”. 18 CHAPTER news
