ABSTRACT:
A process for abating the emission of hydrogen sulfide and nitrogen oxide from a condensate of steam, derived from a sulfide- and nitrite-containing geothermal brine, comprising introducing an oxidizing agent into the condensate in an amount less than that which would be required to directly oxidize all the sulfide and nitrite to sulfate and nitrate. The process optionally provides for periodically introducing a biocide into the condensate to control the growth of organism therein.
