Insitu regeneration

Sulfate-Hydrogensulfate Hydrolysis If sulfuric acid is used as the cation resin regenerant, under insitu regeneration a portion of anion... 

Clearly, the following considerations detract from obtaining the ultimate performance from an insitu regenerated mixed bed on condensate polishing duty ... 

The treatment or service cycle occurs across a mixed bed contained in the operator vessel. Upon termination of the service cycle all the resin is hydraulically transferred to a separation-regenerator vessel for separation by backwashing. Instead of adopting insitu regeneration in this vessel the anion resin is further physically transferred to another column for separate regeneration, whilst the cation resin is separately regenerated in the separation vessel. Finally, the cation resin is transferred to the anion vessel, air mixed, rinsed, and returned to the operator.
