Vapor-side corrosion in thermal desalination plants

This article reports the results of vapor-size corrosion monitoring studies carried out in multistage flash (MSF) desal unit No. 100 of Al-Khafji power and Desalination Plant in Saudi Arabia. Corrosion behavior of 70/30 Cu-Ni alloy, carbon steel (CS), and type 316L stainless steel (SS) was studied in vents and in the vapor size of distillers for 2,000, 4,000, and 9,000 h. Analyses of the experimental data indicated that in addition to O{sub 2}, S-containing compounds evolved during flashing of seawater reacted more with Cu-Ni alloy than with CS and type 316L SS. Explanations for comparatively higher corrosion of alloys exposed to the vapors of the first three (1 to 3) and middle (11 to 13) stages of the MSF plant are given with experimental results. Type 316L SS was found to be the alloy most resistant to vapor-side corrosion in all stages of distillers.
