A cyclic process for the removal of H2S from gas streams is disclosed, the process being characterized by reaction of the H2S to sulfur employing polyvalent metal reactant solutions, and by a novel sulfur recovery scheme. Sulfur recovery, either before or after regeneration, is accomplished by separation of the sulfur-containing admixture into lean and concentrated solutions, and by extracting the concentrated solution with a compound having the formula CnH2n+1OH, wherein n is a number from 4 through 18.
