Chemical filtration for steam purity
Few industrial process systems are as vulnerable to corrosion as the steam generating loop of an electric power plant. Impurities inevitably migrate into the steam cycle, and must be removed to prevent turbine blade corrosion. It is critical to understand the behavior of the condensate polishing resins used to remove the impurities. The Electric Power Research Institute (EPRI) participated in investigations involving ion chromatography which identified chloride as a problem in studies of regeneration and polishing procedures. A modified regeneration procedure consists of ammonium sulfate treatment of the resin before and after ammonia recirculation, followed by a dilute ammonia rinse. A joint study with Southern California Edison also simulated condenser leaks to find the effect of cooling water intrusion.
