随着石化企业加工技术的发展,特别是高硫原油的加工,介质腐蚀性愈加严重,其中硫化物对设备的腐蚀常见于炼油和石油化工设备中。有关研究表明:20世纪80年代中期前投用的设备70%以上是因为设计选材不当,结构不合理,焊接缺陷引起的失效;而90年代末投用的设备70%以上是由各种腐蚀引起的失效。本文结合H_2S在各种不同条件 With the development of processing technology in petrochemical enterprises, especially the processing of high-sulfur crude oil, the corrosion of the medium becomes more and more serious. The corrosion of the sulfide in the equipment is common in the refining and petrochemical equipment. The research shows that more than 70% of the equipment put into operation before the mid-1980s was due to improper design, improper structure and failure caused by welding defects. More than 70% of the equipment put into use in the late 1990s was caused by various kinds of corrosion The failure. This article combines H 2 S in various conditions
