摘　　要：乙烯装置停工检维修时,系统内大量的急冷油需要退料倒空至界外的储罐。急冷系统由于物料量大、油品粘度高、倒空步骤繁复,是乙烯装置停车过程中的难点和控制点。对某大型乙烯装置急冷区急冷油系统在停工检维修时急冷油的倒空量和退料时间进行了分析和计算,对急冷油退料和洗涤急冷系统汽油的操作路径和安全性进行了说明,并对乙烯装置急冷区的工程设计提出了优化建议。During shutdown maintenance,lots of quench oil needs to be retreated from quench oil system to storage tanks outside the battery limit.As a big system with high-viscosity oils and complicated retreating steps,quench oil system is one of the key control points during the shutdown maintenance of ethylene plant.This paper analyzes the retreating situation of a quench oil system in a large ethylene plant,calculates the retreating volume and time of quench oil during shutdown maintenance,introduces the operation path and safety of the retreating quench oil and the quench oil system washing gasoline,and gives some suggestions for the optimization of the engineering design of quench area in ethylene plant.
