ABSTRACT:
A process for removing calcium from an amine-water solution is provided by using a low calcium cationic exchange resin which preferably has large pores to avoid hydrocarbon coating of the resin. Preferably, the resin is pretreated to reduce calcium concentration of the resin to less than two parts per million prior to use for calcium removal.
