COMPACT SEPARATION SYSTEMS

eProcess Wellhead Desander cyclones are pressure
drop dependent, where multiphase fluids are directed
into the cyclone causing the fluids and particles to spin
under a centrifugal force. These strong forces cause
the solidsand fluids to separate.
Gas in particular, disengages and separates quickly. The
heavier solids are forced outward toward the cyclone
wall, and the lighter fluids and gas phase migrate in the
opposite direction toward a centre core.
Solids spiral down the cyclone to the underflow outlet,
while the remaining fluids are forced in the opposite
direction to the overflow. The process is a simple and
effective separator, with a 2-3 second residence time,
and no moving parts.

A WELLHEAD DESANDER BY

PROCESS SYSTEM, PROVIDING
THE MOST EFFICIENT SOLUTION
FOR THE SEPARATION AND
REMOVAL OF SOLIDS FROM
MULTI-PHASE FLUIDS.

Production of sand solids from oil gas wells is a flow
assurance issue for processing facilities. It’s often caused by
unconsolidated reservoirs, high production rates, or the failure
of gravel packs and other sand control measures.
Detrimental effects of sand production include mechanical damage and erosion to
chokes,flowlines,controlvalves,pumpsandotherequipment;decreasedequipment
capacity due to reduced residence time; partial blockage of pipelines, and high
environmental discharge costs.
Solids handling is an increasingly important task, and an efficient process dealing
with the problem needs to address the effective removal of all solids from
multiphase flows, upstream or downstream of the choke.
WELLHEAD DESANDER
APPLICATIONS
• Wellstream Sand removal;
• Well Test Cleanup;
• Coiled Tubing Cleanup;
• Underbalanced Drilling Operations.
BENEFITS
• No moving parts, low maintenance and reduced downtime, result in significant capital and
operating cost savings;
• Compact; 10% the size and weight of conventional filter systems; ease of mobilisation;
• Activates oil and gas wells previously shut-in due to excessive sand production;
• Eliminates solids erosion on downstream pipework, valves, chokes, and process vessels;
• Provides solids removal prior to oil contamination and eliminates sludge formation and other
difficult solids accumulation problems.
OPERATIONS
• Wellhead Desanders are available in several sizes, separating 98% of particles from
5 to 50 microns and larger, and up to 99% by weight;
• Operating pressure drop requirements vary from 10 to 60 psi, with the larger units handling
solids volumes of up to 20% and the smaller units handling up to 1-2% by volume.
STORAGE TRANSPORTATON
• Solids are typically collected into dedicated secondary accumulator vessels. For high operating
pressures, these are also used to prevent high quantities of gas flashing to atmosphere
during the purge cycle;
• To ensure liquids content in the final batch are minimised, water is reduced by the use of
overflow tank designs. The solids remain, and the water is collected and pumped to a slops tank.
The final sand slurry is typically 80% solids by volume;
• The collected solids are removed either by tank replacement, or by vacuum truck operation.

PRODUCED
WATER TREATMENT
Deoiling Hydrocyclones,
Efficient Primary Treatment
ePROCESS DEOILER HYDROCYCLONE
BASED SYSTEM PROVIDES
AN EFFICIENT, COMPACT,
AND DURABLE PRODUCED
WATER TREATMENT SYSTEM.
eProcess Deoiler hydrocyclones are
pressure drop dependent, where fluids
are directed into the deoiler tube
causing the fluids to spin under
a centrifugal force. These strong forces
cause the two immiscible liquids (oil
and water) to separate. The heavier
water phase is forced outward toward
the cyclone wall and the lighter oil phase
migrates toward the centre core.
By accurately controlling the pressures
across the hydrocyclone the water phase
is sent in one direction to the underflow,
and the oil phase is sent in the opposite
direction to the overflow. The process
is a simple and effective separator,
with a 2-3 second retention time, and no
moving parts.

PRODUCED WATER TREATMENT
Hydrocyclone based process systems are
the most cost-effective solution for tough
produced water treatment cleanup.
Located directly downstream on the water
outlet of the production separator and
upstream of the water level control valve,
these systems operate in a proportional
“pressure ratio” control manner.
Don’ttolerateproducedwaterbottlenecks,preventingmaximum
hydrocarbonsproduction.TheDeoileristhestandardforcompact,
efficient, economic produced water treatment applications,
providing the highest capacity per unit footprint area.
APPLICATIONS
• Pre-separator and De-hydrator capabilities;
• Produced Water Cleanup;
• Free Water Knockout;
• Downhole Water Reinjection.
BENEFITS
• No moving parts;
• Compact, 10% the size and weight of conventional systems;
• Motion has no effect on performance;
• Most efficient, and cost effective solution to water
treatment problems.
OPERATIONS
• Deoilers typically separate over 99% by volume of the lighter oil
phase with particles from 10–20 microns and larger;
• Produced water streams contain less than 1% oil in water, and
typically contain between 1,000 – 5,000 ppm. At these levels
a hydrocyclone based water treatment system will typically
clean water in the range of 10–40 ppm;
• Individual hydrocyclone capacities are dependent on the available
pressure, and the type of cyclone used. Smaller high efficiency
cyclones range from 80–500 BWPD per tube. Larger high
capacity cyclones range from 450 –3,000 BWPD per tube;
• Innovative pressure vessel packaging ensures any customer
turndown requirements can be met, on-line, without downtime.

DESANDING
HYDROCYCLONE
Solids Separation
and Handling

DESANDING HYDROCYCLONE
Solids handling in the oil and
gas industry is an increasingly
important task, and an efficient
process dealing with the
problem needs to address sand
removal from produced water
streams.
Detrimental effects of sand production include
mechanical damage and erosion to chokes,
flow lines, control valves, pumps and other
equipment; decreased equipment capacity due
to reduced residence time; partial blockage
of pipelines, and high environmental discharge
costs.
APPLICATONS
• Solids are typically collected into dedicated secondary accumulator vessels. For high operating pressures, these are typically closed systems,
and are used to prevent high quantities of gas flashing to atmosphere during the purge cycle. For low pressure applications an atmospheric
tank will suffice;
• Solids cleaning is performed by a closed loop cyclonic co-current process system carefully designed to ensure adequate scrubbing through
turbulent flow operation;
• To ensure liquids content in the final batch are minimised, water is reduced by the use of overflow tank designs.
The solids remain, and the water is collected and pumped to a slops tank. The final sand slurry is typically 80% solids by volume;
• The collected solids are removed either by tank replacement, or by vacuum truck operation.
BENEFITS
• No moving parts, low maintenance and little downtime requirements, result in significant capital and operating cost savings;
• Compact; 10% the size and weight of conventional filter systems allow for ease of mobilisation;
• Activates oil and gas wells previously shut-in due to excessive sand production;
• Eliminates solids erosion on downstream process equipment including pipework, valves, chokes, and process vessels;
• Provides solids removal prior to oil contamination eliminates sludge formation and other difficult solids accumulation problems
in separators and other pressure vessels.
OPERATIONS
• Desanders are available in many sizes. Systems used in oil and gas production are typically in the 1 to 10 inch range,
separating 98% of particles from 5 to 50 microns and larger;
• Operating pressure drop requirements vary from 5 to 100 psi, with the larger desanders units handling solids volumes of up to
20% and the smaller units handling up to 1-2% by volume;
• Produced water streams contain less than 1% sand in water, and typically contain between 500 to 1,000 ppm.
At these levels a desander will typically reduce solids loading to 10 to 20 ppm;
• In full wellstream applications a desander will separate all solids up to 99% by weight.

PARTIAL
PROCESSING
Unlocking Production from
Mature and Marginal Fields
ePROCESS PARTIAL PROCESSING SYSTEMS
OFFER AN INNOVATIVE SOLUTION TO CREATE
SPARE CAPACITY IN THE EXISTING FIELD
INFRASTRUCTURE TO ALLOW OPERATORS
TO INCREASE THEIR PRODUCTION BY GAME
CHANGING FACTORS.
Operators of mature or marginal fields
increasingly struggle to maintain production
against an ever rising water cut. The infield
flowliness between WHPs amd CPPs and the
downstream processing facilities on the CPP
become bottlenecked which stifles oil production
due to the rise in total fluids.
A eProcess Partial Processing system, retrofitted
onto a WHP, can separate, treat and discharge a
proportion of the water phase directly from the
multiphase production manifold fluids. Removing
produced water before it enters the topsides
facilities creates spare processing capacity,
allowing the operator to significantly increase
oil production using its existing, and unmodified
production infrastructure.
Wellhead platforms are typically small, have very
limited spare space, are unmanned and have
almost no utility systems. To meet these
restrictions, eProcess Partial Processing systems
are compact, self sufficient, robust, flexible,
intelligent and require minimal utilities to operate.

APPLICATIONS
• Mature Field Developments with High Water Cut Production;
• Infield transfer flowlines between WHP and CPP or Onshore
Facilities - liquid constrained;
• Process plant on CPPs operating above design capacity – liquid
constrained.
BENEFITS
• Separate / Treat up to 95% of the Production Manifold water phase;
• Reduces back pressure on existing producing wells;
• Recover “lost” production from shut in high water cut wells;
• Increase existing facility capacity - bring new/side-tracked wells
online;
• Increase production and enhance the economics of mature and
marginal fields.
OPERATIONS
• Applications can be technically verified with Small Scale Field
Test units;
• Systems fully automated and controlled by PLC based
control system;
• Fully intelligent responds to changes in separated water quality,
online well portfolio and export pressure dynamics;
• Systems tuned to cope with changing fluid production profiles
over field life;
• Separated Produced Water treated to customer defined
discharge quality – typically 30 ppm for discharge to sea, and
50 ppm for re-injection.
PARTIAL PROCESSING
For mature fields, the key bottleneck is
the subsea flowline between a WHP and
the CPP. Replacing or adding a second flow-
line is typically uneconomic and thus the
common solution is to shut in the high
water cut wells to accommodate newer or
worked over wells with lower water cuts.
eProcess Partial Processing systems employ well pressure
energy to drive bespoke cyclonic mechanisms to remove a
proportion of the water phase from the well stream fluids.
There are no moving parts and there is no requirement for
any external power. The reduction in the total fluids exported
from the WHD in the flow line to the CPP creates a reduction
in the export pressure from the WHD which is greater than the
pressure drop utilized by the Partial Processing system. This
implies that a Partial Processing system can reduce the back
pressure on the existing wells, increasing their production output.

eJECT™
TRANSPORTER
Solids Jetting and
Transportation System
The eProcess eJECT™ operates with no moving parts;
itusesmotiveliquid,suppliedfrommostanysource,to
fluidize solids in a controlled manner within a defined
region of the vessel.
Spray flow from the eJECT™ creates a controlled-
vortex which interacts with settled solids across a
1.2 meter diameter zone. This area of the vessel is
swept clean of solids using a low energy cyclonic
pattern. The solids are evacuated through the center
of the eJECT™ into a piping header for discharge from
the vessel. An eJECT™ manifold can be designed to
cover all or part of a vessel.
THE ePROCESS eJECT™ IS A CYCLONIC BASED SOLIDS JETTING
TECHNOLOGY DESIGNED FOR THE FLUIDIZATION,
REMOVAL, AND TRANSPORT OF SOLIDS WHICH
HAVE SETTLED INTO A VARIETY OF
PRODUCTION VESSELS
AND TANKS.

eJECT™ TRANSPORTER
eProcess Technologies provides engineering
for the design and application of the eJECTTM
system. This includes manifold, header and
piping design which is critical for proper
transport of the solids out of the vessel and
to downstream handling.
The piping design must allow for proper velocities to avoid
settling and to avoid excess erosion. This design is verified
through our proprietary models and in-house flow loop testing.
APPLICATIONS
• Test and Production Separators;
• Storage Tanks and Free Water Knockouts (FWKO);
• Corrugated Plate Interceptors (CPI);
• Cyclone Accumulator Vessels;
• Sand Cleaning Systems and Slurry Transport Piping Systems.
BENEFITS
• Efficient and effective removal of solids from oil and gas processes
to prevent emulsions, instrument failure, erosion and corrosion,
pump damage, or off-spec product;
• On-line removal of solids from closed vessels without interruption
of production;
• Controlled vortex evacuation of solids without interference with
fluid interface;
• No moving parts – highly reliable;
• Uses minimal flow and pressure of motive fluids – eliminates erosion
on vessel walls;
• Requires minimal support instrumentation and control equipment
• Concentrated discharge slurry minimizes need for downstream
fluid handling equipment;
• Slurry transport of up to 70% solids by weight across long
distances is possible.
OPERATIONS
• Nominal motive spray flow requirements for a 1” eJECT™
are 5.0-7.5 m³/hr;

operating pressure of the vessel;
• The discharge flow is controlled in a range of 6.0-9.0 m³/hr;
• A 1” eJECT™ can transport up to four tonnes of solids per hour;
• Differential pressure for discharge can be supplied from the vessel
operating pressure or with an outlet eductor.
