Condensate-Return-Systems-Chemtreat
High quality condensate is a valuable component of boiler feedwater. Carbon dioxide and subsequently carbonic acid are typically present in condensate from the breakdown of bicarbonate alkalinity in the feedwater. Carbon dioxide lowers the condensate pH, and carbonic acid corrodes metals. If left untreated, acidic condensate will corrode lengths of condensate return piping, pipe threads, nipples, and elbows, and result leaks and in the deterioration and failure of process equipment. To assure that returned condensate has the proper pH and the lowest possible level of iron, it needs to be treated to achieve acceptable quality.
