摘　　要：蒸馏装置塔顶冷凝冷却系统的"HCl-H_2S-H_2O"腐蚀会严重影响设备正常运行,塔顶冷凝冷却系统的主要防腐蚀措施是"一脱三注"防腐蚀工艺。全面提升"一脱三注"防腐蚀工艺管理水平,实现腐蚀安全管理已经成为石油行业迫切需要解决的问题。笔者引用一些腐蚀监测实例说明正确、及时地实施合适的"一脱三注"工艺可以有效地控制设备腐蚀,取得显著的腐蚀减缓效果,是确保设备长周期安全运行的重要条件,而在线腐蚀监测则能起到监控防腐蚀工艺的作用。HCl-H_2S-H_2O corrosion of the overhead system in crude distillation unit greatly impacts the normal operation of equipment,and the main corrosion prevention measure for the overhead system is called'One Removal and Three Injections'. This article introduces some corrosion control instances to show that proper and timely operation of'one removal and three in- jections'can effectively control equipment corrosion and re- markably inhibit the corrosion.On-line corrosion monitoring can effectively monitor the corrosion prevention technologies.
