Process for treating condensate of steam derived from geothermal brine

摘要: A process is provided for controlling the emission of hydrogen sulfide from, and growth living organisms in, steam condensate cooling towers catch basins used in conjunction with derived from sulfide-containing geothermal brine. The comprises contacting condensate, a substantially continuous manner, small, less-than-stoichiometric amount an oxidizing biocide, such as trichloro-isocyanuric acid or 1-bromo-3-chloro-5,5-dimethyl-hydantoin, which results oxidation precursors ammonium bisulfide to water-soluble sulfite and/or sulfate, slows tower basin. additionally includes periodically larger amounts second dodecylguanidine hydrochloride isothiazalone, provides most control organism Still further, combining gas separated treatment therewith. To prevent system corrosion, may include treating non-organic, phosphate-based corrosion inhibitor scale dispersant.
