Abstract
Phosphate based chemical treatment programs are used in several industrial applications in order to control corrosion on low carbon steel metal surfaces. In cooling systems, for example, phosphates are added to the cooling water to prevent corrosion on low carbon steel heat exchangers and pipes. Because there is a tendency to run cooling systems at higher cycles and process operation at higher temperatures, calcium phosphate scale has become more common in cooling water systems. A new terpolymer able to provide calcium phosphate scale control and dispersion of suspended solids has been developed. The inhibitor has been shown to be effective in highly cycled cooling water and at relatively high temperatures. The efficacy of the new terpolymer at different monomer ratios and molecular weight was also established.
