Air was injected into simulated geothermal brines to determine if the costs and hazards of the hydrogen sulfide oxidation process could be substantially reduced. Oxygen was injected into a two-phase flow of simulated geothermal brine. The data obtained was to identify: the optimum oxygen to hydrogen sulfide mole ratio to remove the H/sub 2/S and still avoid the corrosion problem resulting from excess oxygen, the effect of varying sulfide levels on the effectiveness of oxygen injection and the optimum mole ratio, and the effect of varying the silica, carbonate, and calcium levels on the effectiveness of the process.
