摘　　要：吩嗪是制备染料的主要中间体之一,也可以制备药物和其它化学品,因此吩嗪的分离备受关注。应用Aspen Plus模拟软件中的RadFrac精馏模型和NRTL模型,对RT培司生产废料物系进行优化模拟,得到最优的理论板数、回流比等工艺参数,并就相关参数进行了灵敏度分析。结果表明:精馏后吩嗪质量纯度达到99.5%,回收率达到98.0%以上,满足分离工艺要求。Phenazine is one of the main intermediate of dyes,and it can also preparate drugs and other chemicals.More and more attention has been paid to the Phenazine.Using RadFrac rigorous module and NRTL module of the simulation software Aspen Plus,the simulation were carried out for distillation process of waste from the production of RT Base system.The operation parameters,such as the theoretical stages,reflux ratio were obtained,and the sensitivity analysis was carried out too.The results showed that the mass purity of Phenazine reaches 99.5%,and the recovery rate of above 98.0%,which meet the requirement of products separation.
