Abstract
Disclosed is a method of creating a real-time oxidation-reduction potential signature in a hot water system to detect REDOX stress and inhibit corrosion in the hot water system. The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which analyzes and interprets the transmitted potential to create an oxidation-reduction potential signature for the hot water system. If the signature does not conform to an oxidation-reduction potential setting, the controller is operable to feed one or more active chemical species into the hot water system.
