Direct combustion of high-sulfur coal presents problems. An alternative is the production of low Btu gas from coal. Two advantages of this process are: that the gas is produced under reducing conditiona, with the result that sulfur is converted to H/sub 2/S, which can readily be removed by well-proven absorption processes: and aecondly, the gas can be generated under pressure, permitting some operating economies in an existing power plant, and more advanced power plant design for a new plant. Some diaadvantages exist due to the fact that the operation resembles chemical plant operation with controls of fiow and composition, etc. The Lurgi process is the only immediate commercial application, but the Texaco gasifier, Bamag-Winkler gasifier, Wellman-Galusha gasifier, B&W- DuPont gasifier, Westinghouse gasification process, Union Carbide gasification process, Bi-Gas process, and the Koppers-Totzek gasifier are discussed.
