Abstract:
1. An integrated gasification combined cycle (IGCC) power plant comprising: an air separation unit configured to discharge a nitrogen flow and an oxygen flow; a first heat exchanger coupled in flow communication with said air separation unit, said first heat exchanger configured to heat the discharged nitrogen flow; a second heat exchanger coupled in flow communication with said air separation unit, said second heat exchanger configured to heat the discharged oxygen flow; a third heat exchanger coupled in flow communication with a steam cycle, said third heat exchanger configured to heat a condensate stream received from the steam cycle, and a first adiabatic air compressor coupled in flow communication with said first, second, and third heat exchangers, said first adiabatic air compressor configured to discharge a compressed air flow comprising a first flow and a second flow, wherein said first flow is channeled to said first and third heat exchanger and said second flow is channeled to said second and third heat exchanger.
