Abstract This paper reviews the factors that are hindering the development of models to predict corrosion due to sulfur compounds, naphthenic acids, or both, acting simultaneously on steels within the temperature range typically from 230°C to 400°C. These factors are identified as data scattering that do not distribute normally, variables or factors that do not exert their influence in a gradual manner but as a threshold behavior, and the interactions between the factors of sulfidic and naphthenic acid corrosion; exposure time, temperature, and velocity (shear stress); and the chromium and molybdenum content of the steels (Si content is not discussed). Not dealing with the interactions is probably the largest obstacle, followed by data scattering.

Main Factor

Naphthenic acid corrosion is a kind of corrosion state that occurs frequently in the high temperature locations of the petroleum distillation and secondary processing units. It is the main factor influencing the long-cycle safe operation of petrochemical plants, and also one of the hottest issues to be solved urgently in the petroleum refining industry. This paper overviewed the research progress related to high temperature naphthenic acid corrosion including the mechanisms, influencing factors, test and controlling methods; analyzed the engineering problems in the processing of high acid crude oil, pointed out the shortcomings of current research methods, and proposed the future research suggestions on the corrosion rules and prevention methods.
