Anti-Corrosion Building Blocks for Open Recirculating Loop Cooling Systems

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 galvanized steel.  VpCI materials discussed in this paper are environmentally friendly, biodegradable, and can be made from sustainable resources.  Laboratory test results, pilot test results, and field results will be presented.
