ABSTRACT:
Elemental sulfur is recovered from acid gas containing hydrogen sulfide (H.sub.2 S). Such H.sub.2 S may be produced from any conventional source such as an amine desulfurization plant. The acid gas and the H.sub.2 S therein is contacted with oxygen (O.sub.2) or the oxygen in air in a stoichiometric amount such that one-third, by weight, of the flowing H.sub.2 S is oxidized (the H.sub.2 S is measured and the O.sub.2 thereby controlled). Oxidation takes place thus:
