ADVANCED INTEGRATION FOR IMPROVED INTEGRATED GASIFICATION COMBINED CYCLE EFFICIENCY

摘要

A system and method for increasing the efficiency and/or power produced by an integrated gasification combined cycle system by increasing the integration between the air separation unit island (200) of the integrated gasification combined cycle system and the remainder of the system. By integrating one or more of the nitrogen and oxygen gas product streams (220, 205) from the air separation unit (200) in the remainder of the integrated gasification combined cycle system, heat may be utilized that helps to increase the efficiency of the combustion reaction and/or the gasification reaction used to produce the syngas utilized in the system.
