胜利炼油厂炼制含硫高、酸值大的胜利原油,由于原设计未考虑相应的防护措施(所用材质均为碳钢),在生产过程中,因腐蚀造成事故较多,见图1。图1可看出,1968年至1985年共发生腐蚀事故(设备及工艺管线的腐蚀穿孔、腐蚀泄漏、焊缝开裂、腐蚀爆破等,但并非所有的腐蚀事故都构成一定损失)299起。其中1968年~1970年腐蚀事故主要发生在低温轻油部位的常减压塔顶冷凝冷却系统,由于加强设备腐蚀与防护管理,逐步完善了“一脱
Victory refinery refining high-sulfur, acid value of the victory of crude oil, due to the original design did not consider the appropriate protective measures (materials are carbon steel), in the production process, due to corrosion caused by more, see Figure 1. As can be seen from Figure 1, corrosion accidents (corrosion, perforation, corrosion cracking, weld cracking, corrosion blasting, etc., of equipment and process lines) occurred from 1968 to 1985, but not all corrosion accidents constituted a certain loss. Including 1968 ~ 1970 corrosion incidents occurred mainly in the low-pressure gas oil condensate cooling tower system at the top and vacuum depressurization, due to enhance equipment corrosion and protection management, and gradually improve the "off
