Abstract:
A carbon dioxide separation system (10) comprises a first flow path (12) for directing a fluid comprising carbon dioxide (14) therethrough, a second flow path (16) for directing a sweep fluid (18) therethrough, and a separator (20) comprising a material with selective permeability of carbon dioxide for separating the first and the second flow paths (12, 16) and for promoting carbon dioxide transport therebetween. A carbon dioxide separation unit (22) is in fluid communication with the second flow path (16) for separating the transported carbon dioxide (24) from the sweep fluid (18).
Abstract:
A system (10) includes a gas turbine unit (12) configured to generate a combustion gas by combusting a mixture of compressed air and fuel and generate electric power by expanding the combustion gas. A separator (32) is coupled to the gas turbine unit (12) and disposed upstream of the gas turbine unit (12). The separator (32) is configured to reduce sulfur content in the fuel before being fed to the gas turbine unit (12). A portion of an exhaust gas from a gas turbine (18) is recirculated to the gas turbine unit (12).

Abstract:
Disclosed herein are systems and methods for reducing power plant (6, 8) CO 2 emissions. In one embodiment, a method for reducing emissions in a combustion stream, comprises: combusting a gaseous stream to produce an exhaust stream comprising carbon dioxide, and separating CO 2 from the exhaust stream by passing CO 2 through a membrane to produce a CO 2 product stream and a CO 2 lean exhaust stream.
