Cooling systems are crucial components of many processing and manufacturing plants.
It is important to maintain these systems and keep them in good working condition. One
problem faced during maintenance is corrosion. Corrosion mitigation is often time consuming
and costly. The goal of this paper is to show the effectiveness and advantages of Vapor
Phase Corrosion Inhibitors (VpCIs) in the protection of different metals of open recirculating
loop cooling systems including copper and galvanized steel. VpCI materials discussed in this
paper are environmentally friendly, and can be made from biodegradable and sustainable
resources. Laboratory test results, pilot test results, and field results will be presented.
Key Words: Corrosion, Cooling, Open Recirculating Loop, Water Treatment
