Abstract:
1. A method for demineralizing condensate in a nuclear power plant by using a condensate demineralizer comprising a mixed bed of a strongly acidic gel-type cation exchange resin and a uniform particle size strongly basic porous anion exchange resin, said method comprising: passing the condensate through the mixed bed, wherein the mixed bed is regenerated when the ion exchange resins of the mixed bed are consumed to a certain extent, and the regeneration comprises at least one of the following steps (i) and (ii): (i) separating the cation exchange resin from the anion exchange resin, and subjecting only the cation exchange resin to air scrubbing; and (ii) filling a tank for receiving the resins with water prior to transferring the resins to the tank.
