ABSTRACT:
A corrosion control composition and method for boiler/condensate steam systems is provided. Corrosion is controlled by the addition to the feedwater of a relatively high molecular weight amine. The high molecular weight amine is formulated so that at the conditions of temperature and pressure in the boiler/condensate steam system, partial degradation into more volatile amines occurs. The resulting blend of neutralizing amines provides the superior corrosion control of a blend of neutralizing amines from a single amine feed. The preferred high molecular weight amine is dimethylaminopropylamine which will partially degrade into dimethylamine, trimethylamine, methylamine, and dimethylaminopropanol.
