Integrated operation of a pressurized fixed bed gasifier and hot gas desulfurization system
The primary objective of this contract continues to be the demonstration of high fuel gas desulfurization of high temperature fuel gas desulfurization and particulate removal using a moving bed process with regenerable metal oxide sorbent. The fuel gas source for test operation is a fixed bed, air blown gasifier located at GE Corporate Research and Development in Schenectady, New York. The demonstration project also includes the design, construction, installation and test operation of a gas turbine simulator which includes a modified GE MS6000 type gas turbine combustor and a film cooled, first stage LM 6000 nozzle assembly. The hot gas cleanup (HGCU) system and the gas turbine simulator have been designed to operate with the full 8000 lb/hr fuel gas flow from the gasification of 1800 lb/hr of coal at 280 psig and 1000 to 1150 F. An advanced formulation of zinc ferrite as well as zinc titanate have been used as the regenerable metal oxide sorbents in testing to date. Demonstration of halogen removal as well as characterization of alkali and heavy metal concentrations in the fuel gas remain objectives, as well. Results are discussed.
