WebMar 7, 2011 · Similarly, anion resin would be fully regenerated with NaOH and exhausted with acid to make the capacity measurement. Total capacity can be expressed as meq/ml (volumetric) or meq/gm (based on weight). The lab determinations are actually in meq/ dry gm but once the moisture content of the resin is measured, it is converted to meq/ml. If … WebSulfuric acid can cause calcium sulfate fouling of the cation resin. Potassium Hydroxide can be used for regeneration anion resin, but typically costs more than Sodium Hydroxide. …

In condensate systems, after regeneration, the cation exchange resin may optionally be converted to ammonium or amine form.
WebDuring settlement, the cation resin drops to the bottom of the vessel first and the anion resin settles on top. Separation of the two resins is extremely important. If any anion resin remains trapped within the cation resin, the residual anion will regenerate into the Chloride or Sulphate form.
