| Abstract: | The corrosion mechanism and material selection of high sulfur and high acid crude oil in an oil refinery is an ongoing research topic.Continuous updating of relevant standards and specifications guarantees the rationality and suitability of equipment and pipeline material selection,which can effectively inhibit the damage of corrosion to the materials,and thus ensure the long term safe operation of the refining unit.According to the standards and specifications published by API(American Petroleum Institute)and NACE(National Association of Corrosion Engineers),the latest research data at home and abroad,and practical operation experience of the refinery,new viewpoints on corrosion mechanism,influencing factors as well as material selection in the corrosive environment of processing high sulfur and high acid crude oil were summarized and analyzed,which provided reference for the related designers,operators and researchers. |
