摘　　要：根据直接法合成苯基氯硅烷粗单体的特点,在原有分离序列的基础上,采用易分离度系数法,设计出了新的苯基氯硅烷粗单体分离序列,采用Aspen Plus模拟软件,选择NRTL物性方法,应用系统中的DSTWU及Rad Frac精馏模块对流程进行模拟优化,通过灵敏度分析,得到该新流程最优的工艺操作条件。对其精馏塔塔顶、塔釜物流进行夹点分析,利用Aspen Energy Analyzer进行了换热网络的设计,公用工程节能45.9%,为实际生产中的节能改造提供了理论依据。According to the characteristics of phenyl chlorosilane crude monomer,using easy separation coefficient method, the new chlorosilane monomer separation process is designed based on original separation order. The process is simulated and optimized by using DSTWU and RadFrac rectification module, and choosing NRTL physical method in Aspen Plus simulation software. The optimized operation conditions of the new process are determined by sensitivity analysis. The material flows of the top and bottom of the distillation column are analyzed by pinch point method, and the heat exchanger network is designed by Aspen Energy Analyzer. The utility con- sumption reduces by 45.9% after optimization, which provides theoretical basis for the actual production of energy saving.
