摘要
连续催化重整装置原设计未考虑脱除重整生成油中的氯,在装置运行过程中,油中的氯、氮化合物与氢、水结合反应生成盐酸、氯化铵。盐酸严重腐蚀脱戊烷塔空冷器和换热器;氯化铵在低温部位结晶导致回流泵、产品泵机械密封泄漏。通过增加油相脱氯罐脱除油相中的氯,解决了分馏系统的堵塞和腐蚀问题。
The chlorine in the reformate were not considered in the original design of continuous catalytic reforming. In the unit operation, chlorine, nitrogen compounds and hydrogen,H20 react to give hydrochloric acid and ammonium chloride.Then the hydrochloric acid seriously corrodes air-cooled condensers and heat exchangers of depentanizer.And ammonium chloride crystallizes at low temperature parts leads to mechanical seal leakage of reflux and product pump. By adding a tank with dechlorinating agent to removal the chlorine in oil,problems of blocking and corrosion were solved in fraction system.
