Control system for monitoring localized corrosion in an industrial water system

Abstract

A control system is disclosed for monitoring and controlling localized corrosion in an industrial water system, comprising: measuring quantitative localized corrosion rate and at least one controllable water chemistry variable; identifying mathematical correlations between the quantitative localized corrosion rate and the at least one controllable water chemistry variable; establishing mathematical correlations between the controllable water chemistry variable and at least one chemical treatment feed; defining an index derived from current and future values of the localized corrosion rate and an index derived from current and future values of the at least one chemical treatment feed; utilizing a processor to minimize the index of the localized corrosion rate and the index of the at least one chemical treatment feed and determine current and future values of the at least one chemical treatment feed; and implementing only a current value of the at least one chemical treatment feed within the water system.
