Continuing studies relative to the utility of anodic protection as a means of minimizing corrosion have provided data pertaining to new application areas and additional information concerning previously established applications. New application areas include protection of mild steel vessels containing various monoethanolamine solutions, the prevention of stress corrosion as well as general corrosion reduction of various stainless steels exposed to high temperature dilute sulfuric acid, reduction of iron pick-up in mild steel pipe-lines transporting concentrated sulfuric acids. Additional data affecting the previously considered applications to mild steel vessels storing nitrogen fertilizer solutions include vapor space protection and a method of circumventing the high current requirements associated with the critical current peak. Data from a field evaluation of a mild steel heat exchanger containing high temperature concentrated sulfuric acid is presented as well as data from other investigations.
