Naphthenic acid corrosion has been a problem in the refining industry for many years. Recently interest in this problem has grown because crudes that contain naphthenic acid are being recovered from areas which were not known to produce this type of crude, such as china, India, and Africa. New techniques for identifying naphthenic acid corrosion and chemical treatments for preventing this attack are presented. Refinery case studies include stream analysis, failure analysis, and inhibitor use. Laboratory tests to show the effect of hydrogen sulfide and phosphorus-based inhibitors are discussed.
