5. Executive Summary
The goal of this six-year (July 09, 2003 - October 08, 2008) DOE sponsored project
is to make compact separators and compact separation systems predictable, reliable and a
viable economic alternative to conventional separation technology. There are two overall
objectives of this six-year, three-budget-period cooperative agreement. The first objective is
development of Compact Multiphase Separation Systems (CMSS ) for onshore and offshore
applications by integrating the already developed and to be developed individual
components. The second objective is to adapt the developed compact separation system for
Floating Production Storage and Offloading (FPSO) and subsea applications. At the
completion of this project The University of Tulsa will release to the public domain a final
report describing their findings and recommendations. This technology is intended for use
by oil and gas production companies and production equipment manufacturers.
The initial phase of the project (Budget Period I - 07/09/2003 to 10/08/2004) will
focus on the development of additional individual compact separation components, such as
the horizontal pipe separator (HPS ), for obtaining clean oil stream from oil-water mixture,
flow conditioning components, such as the helical pipe (HP) and slug damper (SD ), for
dissipating slugs upstream of the compact separators. The project will also design and test an
upstream slug train generator (SG).
The second phase of the project (Budget Period II - 10/09/2004 - 10/08/2006) will
include the design and construction of the existing flow loop modifications to enable high
pressure testing. Experimental and modeling investigation of the integrated CMSS for
different configurations will be carried out in order to evaluate the performance of the
individual separation components, integrated in the CMSS , and the total system
performance. Experimental results will be used to evaluate the individual component's effect
with respect to CMSS overall system efficiency. CMSS prototypes will be prepared for
In the final phase of the project (Budget Period III - 2006 - 2008) dedicated control
strategies will be studied and developed for the CMSS . Also, a universal model for
prediction of droplet size distribution, in the individual subsystem components and the
integrated system, will be developed. High Pressure testing (up to 1000 psia) with crude oil
will be conducted at available suitable experimental loops (such as Colorado Engineering
Experimentation Station - CEESI) to evaluate the reliability of the integrated compact
separation system and improve the design model, prior to implementation in the field.
Software simulators will be developed for the proposed CMSS s, to be used by the industry
as design tools. The final product of the project will be the design of a CMSS prototype to
be tested in a subsea or FPSO application.
This report presents a brief overview of the activities and tasks accomplished during
the part July 09, 2003 - October 08, 2004, related to the Budget Period I (July 09, 2003 -
October 08, 2004) of the DOE project titled "Design and Development of Integrated
Compact Multiphase Separation System (CMSS )". An executive summary is presented
initially followed by the tasks of the current budget period. Then, detailed description of the
experimental and modeling investigations are presented. Subsequently, the technical and
scientific results of the activities of this project period are presented with some discussions.
Here’s what’s next.
