Condensate polishing is a process used to purify the steam condensate produced in high-pressure steam generation facilities[1][2][3][4] such as those in large thermal power plants.[5] Steam condensate is the water formed by condensing the exhaust steam from the steam-driven turbines in thermal power plants and which is recycled for reuse as the major part of the steam generation feedwater.
Condensate polishing is a unique application of ion-exchange resins that removes suspended and dissolved impurities from the condensate. It is essential for the very stringent quality required of high-pressure steam generation feedwater.
