Corrosion and material Selection in desalination Plants

This presentation discusses the corrosion behavior of materials in environments surrounding the desalination plants with special reference to the different sections of the plant which are vulnerable to corrosion failures.

Furthennore, the occurrence of various forms of corrosion during the operation of a desalination plant is described,and the role of local attack is emphasized. The presentation also encompasses the criteria for the selection of materials for different sections of the desalination plant which basically depend upon the nature of the corrosive environment and operating conditions.

The short-comings of some of the materials currently employed are highlighted and the introduction of new materials either in the existing plant as the possible replacements or in future plants is discussed.
