摘　　要：应用Aspen Plus软件模拟计算一甲基三氯硅烷和二甲基二氯硅烷体系分离过程,考察了单塔精馏和三种双效精馏流程。在相同进料条件下,对比了不同流程的能耗与年度总费用。结果显示,对于所研究的一甲基三氯硅烷和二甲基二氯硅烷体系,双效并流流程是最佳精馏流程,年度总费用比单塔精馏降低了40.08%。Aspen Plus software was adopted to simulation the separation of methytrichlorosilane- dichlorodimethylsilane,and single column distillation with three types of double- effect distillation was researched. Compared the Energy consumption and the annual total cost of different process in the same feed condition. The results showed that,for the methytrichlorosilane- dichlorodimethylsilane separation system,the double- effect feed- split distillation was the optimum distillation process.Compared to single column distillation,the double- effect feed- split distillation saved 40. 08% of the annual total cost.
