Pressure Swing Reforming: A novel process to improve cost an efficiency of CO2 capture in power generation

As applied to CO2 capture, PSR's syngas product is shifted and separated to yield hydrogen and a sequesterable CO2 stream. The hydrogen is used to fuel a gas turbine for power generation, and is also used to fuel the PSR. The power turbine is further integrated by borrowing compressed air from the turbine to use as a combustion source within the PSR. Recovering CO2 from high pressure syngas can reduce separation cost, just as in IGCC. But unlike IGCC, PSR is a low-cost reactor system that uses air at the conditions provided by the GT compressor and returns air at conditions appropriate for the expander. Integrated as such, the PSR enables lower cost production of power with CO2 capture.
