摘　　要：对含硫原油的加工过程中常见且腐蚀严重的低温轻油部位腐蚀、湿硫化氢腐蚀、高温硫腐蚀多种腐蚀类型、腐蚀介质的形成过程、腐蚀状况、腐蚀机理,以及采取的工艺和材料防腐蚀措施进行了论述。同时对硫酸露点腐蚀和连多硫酸应力腐蚀开裂两种特殊的腐蚀类型,也从腐蚀机理和防腐蚀措施方面作了介绍。The sulfur content of crude oil processing common and serious corrosion of the low-temperature corrosion of naphtha site, wet hydrogen sulfide corrosion, high temperature sulfur corrosion of a variety of corrosion types, the formation of corrosive medium, corrosion, corrosion mechanism, as well as to take the process anti-corrosion measures and materials were discussed. At the same time, sulfuric acid dew point corrosion, and even many sulfuric acid stress corrosion cracking of two particular types of corrosion, but also from the corrosion mechanism and anti-corrosion measures were introduced.
