What does CPP stand for?

Condensate Polishing Plant

A Condensate Polishing Plant (CPP) is a water treatment system used in power plants, particularly in steam-powered electrical generation facilities, to remove impurities from the condensate stream before it is recycled back into the boiler. The condensate stream is the water that has been condensed from steam after it has been used to drive turbines in the power plant.

The condensate contains impurities, including dissolved minerals, salts, and other contaminants, which can cause corrosion and scaling of equipment, reducing the efficiency and lifespan of the power plant. The CPP uses a series of physical and chemical treatments, such as ion exchange, activated carbon filtration, and chemical dosing, to remove these impurities and produce high-quality water that can be reused in the power generation cycle.
