ABSTRACT:
A process for the removal of H.sub.2 S and COS from gas streams containing high concentrations of H.sub.2 S is described, the process being characterized by close integration of absorption and reaction techniques. In particular, the bulk of the H.sub.2 S is first absorbed from the gas stream, the balance being removed by oxidation after treatment of the stream to hydrolyze the COS.
