<p>A composition and method for controlling corrosion in aqueous systems with multiple metallurgies such as industrial cooling equipment is disclosed. The composition generally includes: 1) a triazole chose from the group consisting of tolyltriazole and benzotriazole, 2) an aliphatic mono- or di- carboxylic acid having from 8-38 carbon atoms this is capable of controlling corrosion of mild steel, and 3) a nonionic wetting agent. In an alternate embodiment, the composition also includes a scale inhibitor chosen from the group consisting of polyol esters, 1-hydrixyethylidene-1,1-diphosphonic acid, amino tri(methylene phosphonic acid), and 2-phosphono-butane-tricarboxylic acid-1,2,4. The method of the invention entails the use of the above compositions in aqueous systems at dosage levels of at least 10 ppm.</p> |
