摘　　要：介绍上游含氯助剂对加工塔河原油的装置造成的腐蚀问题,其对装置腐蚀的影响主要集中在轻组分系统,包括常顶系统以及石脑油系统。应对这一问题的根本措施是上游取消含氯助剂,控制进厂原油氯含量,此外可以通过优化"一脱三注"控制塔顶氯离子含量并做好监检测。The paper introduced corrosion problems caused by chlorine -containing addi-tives using in the upstream operation of the refining unit processing Tahe crude oil , the above mentioned corrosion problems mainly existed in the light components systems such as atmospher-ic tower top and naphtha system.The fundamental measures to solve the corrosion problems were canceling the usage of chlorine -containing additives in the upstream operation and con-trolling on the chlorine-containing of the incoming crude oil , furthermore , content of chlorine ion in the tower top could be controlled by optimization on the desalter and the three injection a-gents such as ammonia , water and corrosion inhibitor and supervision inspection .
