    Abstract: A process for abating the emission of hydrogen sulfide from a condensate of steam, derived from a sulfide-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 to sulfate.
