ABSTRACT:
A process is provided for controlling the emission of nitrogen dioxide from, and the growth of living organisms in, steam condensate cooling towers and catch basins used in conjunction with a condensate of steam derived from an ammonia containing geothermal brine. The process comprises contacting the condensate, in a substantially continuous manner, with a less-than-stoichiometric amount of an oxidizing agent, which results in the oxidation of nitrite in the condensate to a nitrate. The process optionally provides for periodically introducing a biocide into the condensate in an amount which controls organism growth in the cooling tower and catch basin. To prevent system corrosion, the process may include treating the condensate with a non-organic, phosphate-based corrosion inhibitor and scale dispersant.
