Method and system for reducing CO2 emissions in a combustion stream

摘要

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.
