Cost efficient amine plant design for post combustion CO2 capture from power plant flue gas

Publisher Summary The CO 2 capture project (CCP) is a major industrial/government collaboration developing new technology for the capture and geological storage of CO 2 .The initial phase involves the design of a baseline natural gas combined-cycle (NGCC) and a 30-wt% monoethanolamine (MEA) retrofit plant designed to refinery/API standards. The second phase was a value engineering exercise, where changes in equipment and design standards were implemented to create a low-cost retrofit MEA plant. In the final phase, the NGCC and value-engineered MEA plant was redesigned as a new, integrated system. The CCP had developed capital and operating costs for the various design options, and have concluded that there are significant opportunities through value engineering and process integration to reduce the $/C0 2 avoided cost of post-combustion CO 2 capture.
