In a process in which ZnO is used to absorb H2S and/or SO2 from Claus Plant tail gas, producing ZnS, and in which ZnS is regenerated using O2 producing regeneration effluent, the volume of regeneration effluent containing sulfur species which must be further processed is reduced or diminished in quantity by diluting the oxygen containing gas with water prior to regeneration of ZnS to ZnO and thereafter removing at least a portion of the added water.
