Seawater is considered an attractive resource for utilities in many industries such as power plants, refineries, and chemical plants. Seawater cooling systems are used in heat exchangers, for once-through cooling water systems or for recirculating cooling water systems. The metallurgy and materials used in these facilities need to be compatible with seawater and allow good corrosion control. The seawater composition, and suspended solids can cause corrosion, scaling, fouling, microbiological growth and macrofouling problems. Adapted treatments mainly anti-scaling that are supplemented by a biocide are recommended to increase the heat exchanger's lifetime, to avoid unexpected shutdowns, and to control the overall operating costs and reliability. This treatment must also meet the local regulations in force regarding the discharge of seawater, often into the natural environment.

The evolution of practices in terms of sustainability, materials choice, treatment selection and changes to regulations have demonstrated the need to establish this new guide on recommended best practices to support the corrosion management and development of seawater heat exchangers.

Corrosion Management of Seawater Cooling Systems provides an overview of the main seawater heat exchanger systems; different forms of corrosion; biocide treatments, corrosion, and scale inhibitors; the materials used, coatings and cathodic protection and maintenance, and monitoring and control.

The book will be a valuable reference resource for academics, technicians, and engineers who are interested in the corrosion management of sea water cooling systems.
