摘要： 结合中国石油大连石化公司600kt/a连续重整装置的实际运行情况，分析了重整装置氯的来源，阐述了催化剂运转末期氯对重整装置产生的影响，提出了相应的解决措施,即操作中要根据重整产氢中的氯含量及时调整注氯量，保证再生供风干燥，控制好水氯平衡。对脱戊烷塔顶空气冷却器、海冷器等易发生腐蚀的设备加跨线、加阀，使其在泄漏的时候不影响正常生产。同时做好氢气脱氯后的氯含量分析，监控循环氢流量的变化，及时更换脱氯剂，为装置的长周期平稳运行提供保障。

Abstract: The sources of chlorine in the 600 kt/a continued catalytic reforming （CCR）unit of PetroChina Dalian Company and the effect of chlorine on the production at the last stage of the running cycle were analyzed and summarized. Some counter measures were proposed such as adjusting the amount of chlorine injected based on the chlorine content in reformer hydrogen, keeping good water-chlorine equilibrium, changing the dechlorination absorbent in time and adopting some physical anticorrosion measures to ensure long term stable running.
Key words: catalytic reforming, chlorine, salt fouling, corrosion
