Abstract
This invention provides a method of preventing corrosion in industrial water systems. The method includes maintaining a real-time oxidation-reduction potential at a set point, wherein the system is at operating temperature and pressure. A nonlinear equation is derived based upon theoretically derived or empirically collected data. The equation is then used to determine an inflow of active chemical species to the water system.
