Condensate purification process by use of dilute clear lime solution |
摘要 |
There is provided an improvement in the method of regenerating the anion portion of a mixed anion/cation exchange resin bed used for purification of condensate water. The improvement comprises utilizing a clear dilute lime solution substantially free of non-hydroxylic anions. This solution is produced by passing a solution of calcium salt through a strong base anion exchanger in the hydroxyl form, and thus producing calcium hydroxide by salt splitting. The spent resin is regenerated with spent caustic regenerant from a condensate purification process or with fresh caustic. It is preferred that the calcium solution and the regenerant enter the ion exchanger in counterflow pattern to minimize leakage of non-hydroxy ions.
