摘要
,工艺采用连续精馏的方式,使用四个精馏塔,将来自400#%的苯乙烯产品以及循环乙苯、循环苯、甲苯副产品和苯乙烯焦油。
本设计主要以中国石油吉林石化公司苯乙烯车间的工艺参数做参考,并根据吉林市的自然环境、原料来源、交通工具、电力供应等实际情况,对T0403塔所给各个组分的质量分数并经过PROⅡ软件模拟,得出各个塔的理论板数和回流比以及工艺条件,得出本套工艺装置的初试数据。同时本设计完成了苯乙烯精馏工序的物料衡算、热量衡算、并对苯乙烯回收塔(T0403)进行了严格的设备计算。对塔顶冷凝器、塔顶回流罐、所有精馏塔的管进行了详细计算和选型,同时对进料泵也进行了计算和选型。绘制了带控制点的工艺流程图、物料图、设备布置图及管道布置图。

Abstract
The design of the content is million tons of styrene distillation process design, this process using continuous distillation methods, with four distillation columns and a film evaporator, the mixture of dehydrogenation from 400# section distillation of styrene into purity more than % of production, and cycle of ethylbenzene, the cycle of benzene, toluene and styrene by-product of tar.
The design's main basis is Jilin Chemical pany Limited 104 - styrene plant parameters, and according to the natural environment of Jilin City, the source of raw materials, transport, power supply, and so on the actual the simulation of its PRO Ⅱ software obtained the set of process equipment design .plete the entire process of the material balance, the styrene separation tower (T0403) for the strict terms of equipment,.The top condenser carried out a detailed calculation and selection, then a preliminary product design of bottom reboilers, pumps and the backflow cans. Drawing craft process diagrams, equipment layout, and layout of pipes.
Key Words:Styrene; Technology of Distillation; PRO Ⅱ
