Natural-gas processing in the future will encounter significantly more raw sour gas, i.e., gas containing 15--20 mol % H[sub 2]S or greater. Deciding whether to make the significant investment to build a sour-gas treating and sulfur-recovery plant involves many considerations. An operator selecting the optimum gas treating, sulfur recovery, and tail-gas cleanup processes must choose each carefully because each upstream step can affect design and operation of subsequent downstream steps. Reviewed here are current gas treating and sulfur-recovery processes in use today. For this purpose, plants that process sour gas and recover 50 long tons/day (ltd) or more of sulfur will be considered. Sample plants employing major technologies are listed in a table. Such other sulfur recovery, removal processes as Lo-Cat, SulFerox, Stretford, Iron Sponge, SulfaTreat, and Sulfa-Scrub are available to industry. But these processes are normally considered only when the total sulfur to be handled is 15--20 ltd or less. Additionally, many are troublesome to operate and have relatively high operating costs.
