Abstract

A new process for ion exchange softening of water used in Once-Through Steam Generators (OTSGs) by recovering and using the salt content of the blowdown water from the OTSG to regenerate the softener resin is provided, thus eliminating the cost for commercial regenerant salt that would otherwise be needed. Further, the very high purity of the salt recovered in the blowdown inherently results in the production of softened water with hardness leakage levels that are an order of magnitude lower than can be attained using commercial salt, thus reducing scale deposit potential and improving operating efficiency and reliability of the OTSG.
