AmberLite™ Ion Exchange Resins


DuPont™ AmberLite™ IRN99 H


AmberLite™ IRN99 H Ion Exchange Resin is Nuclear-grade, Uniform Particle Size, Gel, Strong Acid Cation Exchange Resin for Water Treatment Applications in the Nuclear Power Industry. It is designed specifically for use in nuclear loops where highest resin purity and stability are required, and where the "as supplied" resin must have a minimum of ionic and non-ionic contamination. These high standards of resin purity enable plants to achieve reliable and safe production whilst reducing the need for equipment maintenance and minimizing the impact of unscheduled outages. AmberLite™ IRN99 H is recognized as the premier cation resin in nuclear power applications due to its exceptionally high capacity and outstanding physical and oxidative stability, all resulting from its very high level of DVB crosslinker. The very high total cation exchange capacity can produce a 15 – 30% increase in operating throughput in the intended applications. Since the nuclear-grade resins from these applications are generally disposed of as rad waste, high capacity and long resin bed life are critical to minimizing rad waste disposal cost and volume. For most users, rad waste disposal cost will often exceed resin purchase cost, so high resin capacity directly translates into savings in these non-regenerable nuclear applications. Furthermore, longer bed life means fewer bed change-outs, less work, less resin handling, and less chance for radiation exposure. In BWR condensate polishing, AmberLite™ IRN99 H can help to achieve the lowest possible reactor water sulfate levels. The exceptionally high 16% DVB crosslinker level gives it the best oxidative stability of any gel cation resin available, thus minimizing the release of sulfonic acid leachables. It is sold in the fully regenerated hydrogen form and intended for use in non-regenerable single bed or mixed bed nuclear systems which demand the ultimate in effluent purity, operating capacity, and resin life. The particle size of AmberLite™ IRN99 H is specifically designed to give an optimized balance of pressure drop, exchange kinetics, and resistance to separation from the anion exchange resin, AmberLite™ IRN78 OH Ion Exchange Resin, when used in a mixed bed.
