10-17: Corrosion Protection of Concrete For Cooling Towers Cleaning Systems

10-17: Corrosion Protection of Concrete For Cooling Towers Cleaning SystemsThis paper will discuss the corrosion protection methodology for concrete as it relates to cooling tower structures. The paper will focus on the cementations repair materials, high build coatings, sacrificial corrosion methods, and impressed current corrosion technology. The paper will provide a basic overview of these technologies and will be focused on the needs of owners, operators, and facility managers of these types of structures.

While effective

Reynolds number sensitivity

the bulk of this paper will consider the exterior concrete shell of a cooling tower in our examples

Oil Company Wilmington Manufacturing Complex

Many benefits accrue to all segments of the industry when cooling towers are certified per CTI Standard STD-201

Nalco was awarded DOE grant to develop a cost-effective integrated solution (chemical and physical) for the use of impaired water and maximize the cycles of concentration

A temporary heat source was used

long-term storage is for an extended period of more than one year

This involved a multitude of factors

Initial attempts to use it as cooling tower makeup ere retarded by serious operating problems caused by excessive growth of bacterial slimes

Treated municipal sewage has been a source of industrial water for more than 25 years

We discuss training
