摘　　要：利用化工流程模拟软件Aspen Plus,DMSO作萃取剂模拟分离苯-噻吩混合物,苯质量分数为80%,利用灵敏度分析工具对萃取精馏塔参数进行优化,利用正交设计和响应面对各参数进一步优化。Aspen Plus单因素优化得到的苯质量分数为99.823 7%,正交设计和响应面优化后的苯质量分数分别为99.900 3%和99.887 7%。响应面法比正交设计和单因素优化分别节省萃取精馏塔再沸器热负荷5.333%和11.140%,响应面法更适于DMSO作萃取剂分离苯-噻吩的模拟优化。The chemical process simulation software of Aspen Plus is used to simulate the separation of benzene and thiophene mixture in which the mass fraction of benzene is 80%. The parameters of the extractive distillation column are optimized by using the sensitivity analysis tool. On the basis of sensitivity analysis,orthogonal design and response surface method are used to perform a further optimization,respectively. The mass fraction of benzene optimized by single factor analysis with Aspen Plus is 99. 8237%. The mass fraction of benzene optimized by orthogonal design and response surface method is 99. 9003% and 99. 8877%,respectively. Response Surface Method（ RSM） can also save 5. 333% and11. 140% of the heat load of the reboiler,respectively. It suggests that the the response surface method is more suitable for the optimization of benzene-thiophene separation,compared with the orthogonal design and single factor methods.
