急冷油塔是乙烯装置的重要组成部分，在生产过程中由于污垢不断沉积而易产生堵塞现象。通过分析确定了燕山石化乙烯生产过程中的急冷油塔装置污垢成分主要为醇、炔烃、芳烃以及烷烃等重油垢；进行了清洗剂成分的选择与复配；通过正交试验和极差分析法得出最佳清洗剂配方：在100℃温度下，以重柴油为基液，其他表面活性剂AEO-3（15%）、JFC（5%）和快速渗透剂T（10%）为辅助试剂；用调配好的清洗剂对填料环进行清洗，清洗效果非常好。该清洗剂配方可应用于化学在线清洗急冷油塔实际作业。

Quench oil tower,an important part of an ethylene cracker,is easy to be clogged due to accumulation of dirt in the production process,which affects the ethylene production.Through analysis by Fourier infrared,the dirt samples from the quench oil tower in the ethylene cracker of Sinopec Yanshan Petrochemical Company contains mainly heavy oil dirt such as alcohol,alkyne,aromatic hydrocarbon and alkane.On the basis of a brief discussion of the fouling scale mechanism,a chemical online cleaning method is adopted,and the selection and compounding of the cleaning agent components are carried out.The reagents are compounded by orthogonal test and analyzed by the range analysis method to obtain the best reagent formulation that at 100℃,with heavy diesel as the base fluid,other surfactants such as AEO-3 (15%) and JFC (5%) and fast penetrant T (10%) are used as auxiliary reagents.The packing ring in the tower is cleaned with the prepared cleaning agent,achieving a very good cleaning.This cleaning reagent formula can be applied to the actual operation of chemical online cleaning a quench oil tower.
