Hydrogen sulfide generation by reaction of natural gas, sulfur, and steam. Report of investigations/1981
One Bureau of Mines goal is to minimize the undesirable environmental impacts associated with industrial plants emitting waste gases containing SO/sub 2/. To help meet this goal, a regenerable flue gas desulfurization process was developed. This process, known as the citrate process, uses a buffered weak acid solution to absorb SO/sub 2/ from the waste gas. The absorbed SO/sub 2/ is reacted with H/sub 2/S to precipitate elemental sulfur and regenerate the solution for recycle. The H/sub 2/S feedstock for the process, if not otherwise available, may be produced by reacting two-thirds of the recovered elemental sulfur with natural gas and steam. Laboratory investigations and pilot plant operations were conducted by the Bureau to determine if H2S from the natural gas, sulfur, and steam reaction was suitable for the citrate process. The laboratory investigations, in which an H2S generator was integrated with other citrate process operations, provided a basis for design and operation of the pilot plant. The objective of the pilot plant was primarily to provide H2S for the citrate process pilot plant at the Bunker Hill Co. lead smelter in Kellogg, Idaho.
