Abstract
A process cooling water (PCW) system and method for an iron or steelmaking application, the PCW system and method including: sampling a plurality of characteristics of PCW using a plurality of sensors; calculating one or more of Langelier Saturation Index (LSI) and Ryznar Stability Index (RSI) based on the plurality of characteristics using a LSI/RSI measurement unit coupled to the plurality of sensors; and injecting one or more anti-scalant chemicals into the PCW responsive to the calculated one or more of the LSI and the RSI in real time using an anti-scalant injection system to thereby control scale formation in the PCW.
