The project objective is to develop engineering evaluations of technologies for the capture, use, and disposal of carbon dioxide (CO{sub 2}). This project emphasizes CO{sub 2}-capture technologies combined with integrated gasification combined-cycle (IGCC) power systems. Complementary evaluations win address CO{sub 2} transportation, CO{sub 2} use, and options for the long-term sequestration of unused CO{sub 2}. Commercially available CO{sub 2}-capture technology will provide performance and economic baselines for comparing innovative technologies. The intent of this research is to provide the CO{sub 2} budget, or an ``equivalent CO{sub 2}`` budget associated with each of the individual energy-cycle steps, in addition to process design capital and operating costs. The value used for the ``equivalent CO{sub 2}`` budget is 1 kg CO{sub 2}/kWh{sub e}. The base case is a 458-MW IGCC system using an air-blown Kellogg Rust Westinghouse (KRW) agglomerating fluidized bed gasifier, Illinois No. 6 bituminous coal feed, and in-bed sulfur removal. Three commercial CO{sub 2} recovery technologies are under study: Amine scrubbing, Selexol, and Rectisol. Three emerging CO{sub 2} recovery technologies are also being evaluated: High-temperature CO{sub 2} separation with calcium- or magnesium-based sorbents, high-temperature molten-carbonate membranes for acid-gas removal, and ambient-temperature facilitated-transport membranes for acid-gas separation.
