摘要： A process for the regeneration of loaded ion-exchange resin comprising (a) providing loaded resin for regeneration; (b) providing first stage and third stage regenerant suitable for regenerating loaded resin; (c) providing a plurality of regeneration vessels; (d) filling a regeneration vessel with a desired amount of the loaded resin before filling another regeneration vessel; (e) once a regeneration vessel has been filled, contacting the loaded resin within the vessel with first stage regenerant in a plug flow to provide a first stage regenerated resin; (f) contacting the first stage regenerated resin with third stage regenerant in a plug flow to provide regenerated resin and (g) removing and collecting third stage regenerant from a vessel containing regenerated resin and adding the collected regenerant to the first stage regenerant.
