Project Highlights
- One of the five largest carbon capture plants in the world.
- Multiphased project including successful DOE down-selections.
- As one of the first membrane technology carbon capture systems, a major portion of the design process focused on evaluating material selections and designing ducting/piping, which included deep vacuum conditions.
- Installed at the Sargent & Lundy-designed Wyoming Integrated Test Center.
Project Description
Sargent & Lundy began supporting the project in Phase 2 to develop a FEED study for the large test pilot. As the large test pilot moved into Phase 3, Sargent & Lundy continued to support MTR with detailed design, installation, and operation. The project team designed the system to treat flue gas, equivalent to a 9.2-megawatt-electric (MWe) capacity. The initial testing met the goal to capture 75% of the CO2 in the flue gas. Additional testing captured more than 90% of the CO2.
The study called for compressing the captured CO2 to 2,234 pounds per square inch absolute (PSIA) to demonstrate the system could achieve pipeline requirements. Following the compression step, the team vaporized and released the CO2 for demonstration purposes.
Project Scope
Sargent & Lundy performed the overall project management and balance-of-plant engineering for the FEED study. The firm provided valuable input and support to MTR and Trimeric, which were responsible for the process engineering, while also working closely with for the on-site installation contractor, Graycor, to develop the Class 2 capital cost estimate and project execution schedule. The deliverables were critical to the Phase 3 continuation application’s approval. The following deliverables and activities completed during the study were critical to gain Phase 3 application approval:
- Developed the flue gas (composition) design basis and project design criteria.
- Detailed 3D model, overall site plan, and general arrangement drawings.
- Auxiliary power sourcing study.
- Water supply, cooling water design, and wastewater treatment evaluations.
- Piping and instrumentation diagrams and piping isometrics.
- Structural steel and ductwork drawings.
- Foundation and civil works drawings.
- Electrical one-line drawings.
- Electrical load list.
- Instrument and I/O lists.
- Controls architecture diagram.
- Major equipment datasheets/specifications used to solicit budgetary quotes.
- Hazard identification facilitation.
- Permit matrix.
- Prepared state environmental permit applications.
- Project execution schedule.
- Capital cost estimate input and review.
- Operations and maintenance estimates for 18 months of operation.
- Study summary report.
Sargent & Lundy supported Phase 3, completing design, leading equipment procurement, and producing construction drawings for Graycor. Sargent & Lundy served as the construction and commissioning management lead and continued a full-time presence on site during the pilot’s construction and commissioning. Sargent & Lundy also led the commissioning effort, including developing commissioning plans necessary to bring the unit online following construction.
