摘　　要：2007年对中国石油化工股份公司4套常减压装置进行了适应掺炼高酸原油的材质升级改造,并对其进行为期1年的腐蚀监测和数据分析,分析计算了不同操作条件下常用材质的腐蚀速率,并将其与API 581附录G中的腐蚀数据库进行了初步对比。监测分析的结果为炼油装置后续的材质升级及新建装置的设计选材提供重要参考。Material improvement for SINOPEC four CD/VD units was to accommodate blending high naphthenic acid crude oils in 2007,and corrosion monitoring of the refinery units was carried out once a month for one year. Some regularity and characteristics in refining high acid crude oils containing sulphur were introduced, then the corrosion rates of some common materials in different operating conditions were analyzed and calculated by means of yearlong monitoring data, and compared with the Appendix G-thinning technical module of API publication 581 standard. The analytical results of corrosion monitoring data could provide advices and references for the following material improvement and the material selection of new plant design.
