| titleOfInvention | Method for regeneration of cation-exchange condensate polishers |
| abstract | A method for treating boiler water condensate to remove undesirable cations which comprises providing a bed of cation-exchange resin, passing water to be treated through said resin bed, and regenerating said resin with an aqueous solution of a salt comprising a volatile amine and an anion selected from anions which do not form precipitates with any cation present in the water to be treated under operational conditions, and wherein the volatile amine is optionally not the same as that employed as the corrosion inhibitor in the boiler water system. The preferred salts include cyclohexylamine citrate, methoxypropylamine citrate, diethanolamine citrate and monoethanolamine citrate. The proposed method is particularly advantageous since the anion of the regenerant salt is selected to avoid the formation of insoluble calcium salts. |
