ABSTRACT:
A process for reducing the hydrogen sulfide content of steam, such as steam produced from a subterranean geothermal reservoir, in which the steam is contacted with an aqueous, alkaline solution having a temperature approximating that of the steam to absorb hydrogen sulfide from the steam which is thereafter discharged or utilized in a power generation plant. Hydrogen peroxide is introduced into a cooled portion of the aqueous, alkaline solution to reduce the hydrogen sulfide content thereof and then the aqueous alkaline solution is heated to about the temperature of the steam and recycled into contact with the hydrogen sulfide-containing steam. The temperature of the cooled portion of the aqueous, alkaline solution into which hydrogen peroxide is introduced is such that thermal decomposition of hydrogen peroxide is substantially prevented.
