ABSTRACT:
The invention provides a method for removing transition metal oxides and soluble cation species from condensate at a relatively high removal efficiency. The method includes hydrating a strongly acidic dual morphology cation exchange resin in a macroeticular, desiccated morphology to produce a macroreticular, hydrated morphology. Condensate which is brought into contact with the resin when it is in a hydrogen form is purified. The condensate may, optionally, also be contacted with an anion exchange resin.
The invention additionally provides a method for selecting cation exchange resins which are particularly suited for use in removing metal oxides from a condensate stream. The method serves to narrow the field of condidates for pilot-scale resin testing with industrial condensate.
