摘　　要：采用Petlyuk模块对SiH_2Cl_2、SiHCl_3和SiCl_4的三元氯硅烷组份采用隔壁塔精馏进行了计算,得到了DWC塔的气液相负荷和组份浓度分布。并分析了回流比、进料位置、副塔采出位置、隔板位置以及Connect streams流量等因素对产品纯度的影响。结果和方法可为DWC精馏三元氯硅烷的工艺设计提供参考。The research investigated the separation of the mixture of SiH2Cl2,SiHCl3 and SiCl4 with the DWC instead of conventional tow towers distillation sequences.The influentces of reflux ratio,feeding location,side-draw location,divided wall location and liquidvapor split flow on the purities of the products are simulated by ASPEN plus using Petlyuk model.
