First Generation coal gasification continues to grow with the expansion of Lurgi process to make gasoline in South Africa and SNG in the United States. This moving-bed gasifier is no doubt the leading commercial application of coal gasification. This can probably be attributed to its operation at the elevated pressure that simultaneously increases coal throughput and broadens the utility of the raw Syngas product by lowering its coal. Other Second Generation processes also strive to achieve high pressure operation: Ruhrgas 100 to improve moving-bed gasification at 100 bars; Texaco, Shell, Koppers, and Saarberg-Otto to improve entrained-bed gasification at 20 to 40 bars; and U-GAS and Westinghouse and the pressurized Winkler to improve fluidized-bed operation at 10 to 40 bars. Operation at 20 to 40 bars greatly improves gasifier productivity and significantly broadens the use of the raw Syngas produced by all types of gasifiers. Future commercial trends will include the entrained- and fluidized-bed concepts at 20 to 40 bars while even higher operating pressures will be used for the Lurgi moving-bed concept.
