A process for treating non-condensible gas streams containing H2S, and for treating steam containing H2S, is disclosed, the process being characterized by unique division of the non-condensible stream, or of a separated noncondensible H2S-containing stream derived from the steam, with diverse oxidative treatment of the separated portions. The invention is particularly suited to treating the exhaust steam from a steam turbine which utilizes geothermal steam as the working fluid. In a preferred aspect, disposal of sulfur produced as normal byproduct of liquid oxidative steps may be reduced or avoided altogether by reaction of the sulfur with bisulfite and/or sulfite produced in the procedure to produce soluble thiosulfate.
