A simple and potentially inexpensive method for removal of H/sub 2/S from noncondensible gases evolved in geothermal flash processes has been successfully tested on a small scale in the field. The method consists of scrubbing the noncondensible gases of H{sub 2}S with brine effluents which contain relatively high concentrations of Pb, Zn, and Fe such as those of the Salton Sea and Brawley Geothermal Fields in the Imperial Valley, California. For plant applications, noncondensibles including H{sub 2}S would be ejected from a surface steam condenser (necessary to minimize the volume of liquid in contact with H/sub 2/) and scrubbed with effluent brine just prior to preinjection clarification. The metal sulfide precipitates are removed in the clarification step and the noncondensibles, less H{sub 2}S, are vented as usual.
