  • Sodium-selective cation exchange resins for ammonia-cycle condensate polishing
    Patent number: 4857202
    Abstract: Ion exchange resin beds used for ammonia-cycle condensate polishing show enhanced selectivity for sodium ions over ammonium ions when conventional, monosulfonated cation exchange resin is replaced with polysulfonated cation exchange resin. This enhanced selectivity results in a lower concentration of sodium ion leakage and longer bed life to critical leakage, compared with conventional, monosulfonated resins.
