摘　　要：氯丙基三氯硅烷精馏塔是γ-氯丙基三氯硅烷生产装置中的关键设备,直接影响系统目标产品的合格率。三氯氢硅和3-氯丙烯在反应器内进行硅氢加成反应制备γ-氯丙基三氯硅烷,经分离后得到丙基三氯硅烷和γ-氯丙基三氯硅烷的混合物,在设定塔顶丙基三氯硅烷和塔底γ-氯丙基三氯硅烷目标质量分数均为0.99的前提条件下,采用Aspen Plus软件进行精馏塔简捷设计、精馏塔严格设计和灵敏度分析优化。结果表明:塔板数为15块,进料位置为第9块塔板,回流比为5.09,是满足精馏塔设定分离目标较适宜的工艺设计,同时也是能源消耗和设备投资较少的方案。Theγ-chloropropyltrichlorosilane rectification tower is a key equipment in the production of γ - chloropropyltrichlorosilane, which directly affects the qualification rate of the target product in the system. γ-Chloropropyltrichlorosilane was prepared by hydrosiloaddition reaction of trichlorosilane and 3-chloropropylene in the reactor. After separation, a mixture of propyltrichlorosilane and γ - chloropropyltrichlorosilane was obtained. Under the premise that the target mass fractions of propyltrichlorosilane at the top and γ- chloropropyltrichlorosilane at the bottom of the rectification tower were both 0.99, Aspen Plus software was used to optimize the simple design of the distillation column, the strict design of the rectification tower and the sensitivity analysis of the distillation column. The results show that the number of plates is 15, the feeding position is the 9th plate, and the reflux ratio is 5.09, which is the most suitable process design to meet the separation goals set by rectification tower, and it is also a scheme with less energy consumption and equipment investment.
