摘要
The present invention relates to a composition and method for inhibiting chloride-induced corrosion and limescale formation on ferrous metal surfaces and alloys in process systems in which aqueous solutions are concentrated, the composition containing a corrosion inhibiting amount of at least one polycarboxylic acid and/or its alkali metal or alkaline earth metal salts and a sufficient amount of a base to bring the water to a pH effective to inhibit both chloride-induced corrosion and limescale formation.
