Critical Ion Exchange Technology for Steam Generation

Steam generators in Nuclear Pressurized Water Reactors (PWR) electric generating stations are vital components in the power generation cycle. In addition to high-purity condensate, many steam generators are used to blow down demineralizers to help maintain quality for efficient operation and extended steam generator life. Graver Technologies has worked with several utilities to evaluate and develop specialty products to maintain an optimum generator and cycle performance. Several special cation-to-anion ratio mixed beds are quite useful, providing additional cation capacity to extend run length. One Gravex® mixed bed is made with a macroporous cation in the amine form. This particular morpholinium form cation resin is selective for sodium, thus maintaining high purity levels. Our Ultra-Low-Chloride anion can be utilized to help keep chloride at the lowest level possible in a high pH environment. Although developed for condensate, the low ppt chloride Gravex is beneficial for steam generator performance. Graver Technologies has the right product for your steam generator blow-down demineralizers.
