Abstract
A method of operating an integrated gasification combined cycle power generation system is provided. The method includes compressing air in an adiabatic air compressor to produce a compressed heated air stream, heating a nitrogen stream using the compressed heated air stream to produce a heated nitrogen stream and a cooled compressed air stream, and channeling the cooled compressed air stream to an air separation unit.

1-10. (canceled)
A integrated gasification combined cycle (IGCC) power plant comprising:
- a first heat exchanger configured to generate steam from a first condensate stream;
- an air separation unit configured to discharge a nitrogen flow and an oxygen flow;
- a second heat exchanger coupled in flow communication with said air separation unit, said second heat exchanger configured to heat the discharged nitrogen flow and the condensate stream;
- a third heat exchanger coupled in flow communication with said air separation unit, said third heat exchanger configured to heat the discharged oxygen flow and the condensate stream;
- 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 heated air flow comprising a first flow and a second flow, wherein said first flow is channeled to said first and second heat exchanger and said second flow is channeled to said first and third heat exchanger.
