High temperature Naphthenic acid corrosion is a major problem for the safe and long-period operation of the refining units during high acid crude oils processing. because of the numerous and complex influence factors of naphthenic acid corrosion, and the complexity of engineering practice, it is more difficult to completely understand for mechanism, prediction and controlling of naphthenic acid. Low-temperature naphthenic acid corrosion, types and corrosivity of naphthenic acid, interactions of sulfidic and naphthenic acid corrosion have been summarized and analyzed. Prediction and selection material of naphthenic acid corrosion have been generalized and discussed. In addition, the study on mechanism and controlling of naphthenic acid corrosion in the future is suggested.
