INTEGRATED AIR SEPARATION PLANT - INTEGRATED GASIFICATION COMBINED CYCLE POWER GENERATOR

摘要

An integrated cryogenic air separation unit power cycle system has a cryogenic air separation unit (1), a fuel gasification unit (2) and a gas turbine (3). The air separation unit (1) provides oxygen (48) to the gasifier unit (2) and nitrogen (104) to the expander (210,212) of the gas turbine (3). Feed air (18) to the air separation unit (1) is supplied via a compressor (12) independent of the compressor (202) used to supply air (204) to the combustion zone (208) of the gas turbine (3). Preferably, nitrogen (104) is supplied to the combustion zone (208) and the air separation unit is operated at 8 to 20 bar (0.8 to 2.0 MPa).
