This document summarizes the design and construction of a Mixed Bed Polisher (MBP) facility in Port Wentworth, Georgia. The MBP facility was designed to remove impurities from boiler feed water before it enters the boiler system. A 3D model was created to help with layout and identify any design issues. Construction crews then installed the piping, vessels, and equipment according to the design drawings and models. The MBP facility was commissioned in December 2016 and is now successfully polishing boiler feed water and removing contaminants as intended.

1. Port Wentworth, Georgia
Mixed Bed Polisher
(MBP)
ENERGY OPTIMIZATION PROJECT NO. PW13901
BY AUSTON BAGNAS (MBP DESIGNER)
YEAR 2016

2. Project Overview:
This project is intended to remove impurities from
the boiler feed water process.
This facility would be located before the boiler and
reduce contaminates from entering the boiler
system.
Contaminates can clog or foul piping within the
boiler system.
This would affect the quality and quantity of the
process and may require additional shut down
maintenance periods to repair any damage
caused by these impurities.

3. Ideation Process:
Layout:
The vendor supplies assemblies were skid based equipment
and had no layout requirements. Layout was primarily dictated
on available space and distance between assemblies.
Placement:
An existing building scheduled for demolition was chosen to
house the facility.
Process:
Since this facility polishes boiler feed water it was located at
the near the boiler feed water tank.
Maintenance:
The mill had a lot to say about the general arrangement on
this project. Maintenance and operations from the mill helped
determine how this facility would operate. Therefore the layout
was greatly determined by the accessibility to the assemblies
in the facility.

4. Piping & Instrumentation Diagram (P.&I.D.s)
A flow diagram, or piping schematic, is used
to show the process flow for a facility or
process.
This design was a collaboration with the
vendor, myself, and the project engineer for
the CRP facility.
This flow diagram best represents how the
piping will be designed. It also locates
instrumentation and assemblies that will be
installed.
This drawing is a valuable source of
information for other drawings such as the
piping plans, isometrics, tie-in drawings, and
can further be used by operations after
installation.

5. General Arrangements (G.A.s)
The general arrangements are drawn to show tank & vessel locations along with the structural design
and sometimes maintenance access. These drawings are very basic for clarity.

6. Piping Plans & Sections
These drawings show the piping layout, vessel locations, and structural information. The P.&I.D.s, G.A.s, Tie-in
drawings, and isometrics will be the primary source for information when installing prefabricated items on this project.

7. MBP 3D Model
A 3D model was created to best identify any
layout concerns.
The skids & vessels were created and inserted
along with the chemical containment and any
large bore piping.
Multiple disciplines were incorporated into the
design. Access for electrical and instruments
were considered. The structural department
located steel members based on a stress
analysis of the building. Foundations were
designed to accommodate pumps and vessels.
A containment was designed and added as
well.
Many existing vessels and structures were
used in this project. They were also modeled to
show any interferences and possible uses.

8. MBP 3D Model (cont.)
Alternating views were utilized for
orientation and installation of assemblies
and equipment. Instrumentation was
able to identify locations for instruments
and junction boxes based on space and
accessibility. Repair, removal, and
maintenance was also considered in
locating any equipment.
Sample locations were installed for
operations to conduct necessary
analysis of the process.
This model was also used by
construction to better understand how
the facility would look when installed.

12. Construction & Installation
After pipe and vessel fabrication construction
crews began installation of the facility. Here are
two photos taken during the construction phase
of the MBP facility.
Scaffolding is erected for access and
installation of piping.
Minor field modifications were made. I was
onsite and able to work through some
unforeseen challenges.

13. Installed, commissioned, & running.
December 2016 the MBP was finally brought online and is now
successfully polishing condensate and removing impurities from the
boiler feed water.
There were a couple lessons learned on this project, one including an
over designed feed pipe but nothing substantial.
Overall the project was a great success and finalized on time and on
budget.
