Sea Water Corrosion Test Program
From Introduction: "The first demonstration plant sponsored by the Office of Saline Water was located in Freeport, Texas, and came 'on stream" in 1961. The incoming sea water was deaerated since both Speller (6) and Uhlig (7) recognized that dissolved oxygen was usually the controlling factor in the corrosion of iron stream condensate at temperatures even as high 400 degrees F. The water was acidified prior to daeration with H2SO4 to decompose the carbonates which subsequently would cause scale when the water was heated. After the carbonates were removed, the pH was raised to the neutral point, again to provide a less corrosive environment."
