Abstract
The present invention relates to a method for purifying aqueous solutions or condensate in a three component resin system comprising a mixed bed of a strongly basic anion exchange resin, a strongly acidic cation exchange resin and a weakly acidic cation exchange resin. According to the present method, aqueous solutions can be treated to remove metal ions and corrosion products along with ammonia and other volatile amines so that metal ion leakage is substantially reduced and the run length of the resin system is increased. A method for separating and isolating the resins of the three component system is also described.
