ABSTRACT:
A process for treating and deriving useful energy from a two-phase geothermal brine containing non-condensible gases, including hydrogen sulfide, and also containing heavy and/or transition metals in solution, wherein the non-condensible gases are separated from the geothermal brine. Substantially all of the hydrogen sulfide contained in the non-condensible gas is converted to sulfur dioxide and at least a portion of the sulfur dioxide is removed from the non-condensible gas thereby rendering the same environmentally acceptable for discharge. The separated geothermal brine is flashed to a high quality steam utilized for energy derivation. The portion of sulfur dioxide removed from the non-condensible gas is added to the remaining brine for reinjection into the subterranean geothermal reservoir.
