Improve corrosion and deposition control in alkaline cooling water systems
- Betz Water Management Group, Horsham, PA (United States)
Utility operators can use a calcium carbonate inhibitor to improve corrosion control and meet environmental discharge limits for phosphorus on cooling water systems. Due to volume, maintaining cooling towers` operating parameters such as pH, Cl{sub 2}, cycles, etc., are a huge endeavor to balance water chemistry. The goal of a cooling water system is to provide a reliable heat-transfer medium--water--to numerous exchangers without impairing the energy transfer efficiency. Traditionally, alkaline phosphate and alkaline-zinc based programs have been used to control corrosion and minimize scaling of heat-transfer surfaces. However, restrictions on phosphate discharges for water systems are requiring utility operators to seek other water treatment programs. Two case histories show how hydrocarbon processing industry facilities used a calcium carbonate inhibitor to reduce phosphate discharges, control corrosion and maintain heat-transfer efficiency on affected exchangers.
