Coal gasification: the new energy source
This review of coal gasification describes processes available today and in the future. Winkler, Koppers-Totzek, and Lurgi processes are briefly described. The Lurgi Process has been applied extensively for practically all of the first-generation projects. Some new processes include Bituminous Coal Research's BIGAS Process, Consolidation Coal's CO/sub 2/ Acceptor'' Process, and the Institute of Gas Technology's HYGAS'' Process. All these processes use fine coal and employ fluid beds in which the coal particles are either suspended or carried along by the gases in the gasifier. They do not have moving parts inside the gasifier. The processes may allow scale-up to much larger sizes than the Lurgi gasifier and possibly reduce the capital cost for gasifiers. Initial engineering progress for commercial plants is being made on low-BTU gas projects for the power industry and high-BTU gas projects to produce synthetic natural gas. An illustration is described to show the size of the mine and coal preparation plant necessary to support a 250-MMscf/D gasification plant and to show some of the difficulties encountered in the materials handling for a commercial gasification plant.
