Embodiment Construction

[0061] Referring now to the drawings, like numerals in the drawings represent like elements throughout the various views.

[0062] pieces, figure 1 A schematic diagram of a known integrated gasification combined cycle system 100 is shown. For simplicity, only those elements relevant to the subject matter described herein are shown. The overall integrated gasification combined cycle system 100 may have many other configurations and use many other types of equipment.

[0063] Integrated gasification combined cycle system 100 may include one or more gas turbine engines 110 . As is known, gas turbine engine 110 may include compressor 120 for compressing an incoming airflow. Compressor 120 delivers a stream of compressed air to combustor 130 . Combustor 130 mixes the compressed air flow with the compressed fuel flow and ignites the mixture. Although only a single combustor 130 is shown, the gas turbine engine 110 may include any number of combustors 130 . In turn, the hot com...

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...
