Cooling Water Monitoring Using Coupled Multielectrode Array Sensors and Other On-Line Tools

Abstract

Abstract Real-time coupled multielectrode array sensors (MAS) and other monitoring tools were used to evaluate a complex corrosion phenomenon on carbon steel in a large industrial cooling water system. The design and implementation of the monitoring system, and monitoring results are discussed in this paper. Characterization of the degree and depth of attack from the MAS probe showed excellent correlation with characterization of underdeposit attack on corrosion coupons that were exposed simultaneously with the MAS probe.
