Integrated gasification combined cycle system with vapor absorption chilling

Abstract

The invention relates to an integrated gasification combined cycle system with vapor absorption chilling. The present application and the resultant patent provide an integrated gasification combined cycle system (100). The integrated gasification combined cycle system (100) may include a gas turbine engine (110), one or more power plant components (335), one or more carbon dioxide compressors (210), and a vapor absorption chiller (240). The vapor absorption chiller (240) is driven by a waste heat source flow (270) from the carbon dioxide compressors (210) to produce a chilling medium flow (300) to cool the power plant components (335).

Description

technical field [0001] The present application relates generally to integrated gasification combined cycle systems, and more particularly to integrated gasification combined cycle systems using vapor absorption quenching driven by waste heat from a gas compression system. Background technique [0002] In general, carbon dioxide (“CO2”) produced in power generating equipment 2 ”) is considered a greenhouse gas. Therefore, carbon dioxide produced during the overall power generation process is typically sequestered and then recycled for other purposes or otherwise disposed of. In the current Integrated Gasification Combined Cycle (“IGCC”) In the system, pre-combustion capture of carbon dioxide is preferred. Once captured, the carbon dioxide can usually undergo compression prior to transport, disposal, or other use. Specifically, various integrated gasification combined cycle system designs require that the gas be recirculated to Carbon dioxide is compressed prior to, for examp...

Therefore, this type of parasitic load results in lower overall power device net output and efficiency

Also, using cooling tower water to cool CO2 compressors may be cost-prohibitive and impractical in areas where water may be expensive and / or scarce
