重整装置脱丁烷塔铵盐堵塞与腐蚀原因分析及对策

针对中国石化镇海炼油化工股份有限公司连续重整装置在长周期运行过程中出现的重整生成油脱丁烷塔塔盘和塔顶空气冷却（简称空冷）器铵盐堵塞与腐蚀的问题进行了分析。利用氯化铵盐易溶于水的特点，实际生产中采取了在脱丁烷塔空冷器前和进料中注水清洗的方法避免铵盐的沉积，取得了较好的效果，确保了装置长周期运行。

ANALYSIS AND COUNTERMEASURES FOR AMMONIUM SALT PLUG AND CORROSION IN DEBUTANIZER OF CATALYTIC REFORMER

The question that ammonium salt block-up and corrosion in trays and air cooler for the debutanization column of continuous catalytic reforming unit is analyzed, which occurs during the long-term operation of Zhenhai Refining & Chemical Company's continuous catalytic reforming unit. According to the water-soluble property of chlorination ammonium salt, in practical production we use the method water injection cleaning before air cooler for the debutanization column and during charge-in to avoid ammonium salt's deposition, and achieved good practical results, ensure long-term operation of the device.
