Abstract
Underdeposit corrosion is a phenomenon which has historically been the source of many equipment failures. Often, metal oxides represent the source of the deposits; and therefore the control of these foulants is an important part of cooling water corrosion control programs. Additionally, metal oxides can impede the film-forming process of many corrosion inhibitors. This paper describes the use of a combination of sequesterants developed to minimize metal oxide fouling. Laboratory data are provided to illustrate the impact these sequesterants have on a variety of cooling water corrosion inhibitor programs and their efficiency in cleaning fouled surfaces. Information is included on the stability of the formulation and environmental impact.
