采用响应面法（RSM）的设计和优化程序的改造传统的萃取精馏程序的热耦合萃取精馏方案（TCEDS-SR）。可以通过最少的模拟运行以实用的方式找到最佳的TCEDS-SR结构。此外，响应空间模型允许确定和量化变量之间的相互作用。对近沸点混合物和共沸混合物的分离进行了研究，以测试所提出的方法。这些预测与严格模拟的结果吻合得很好。结果表明，与传统的萃取精馏序列相比，将萃取精馏序列改造为TCED-SR可以实现显着的节能。© 2012美国化学工程师学会AIChE J，59：1175-1182，2013
Design and optimization procedures employing the response surface methodology (RSM) for retrofitting the conventional extractive distillation sequence to a thermally coupled extractive distillation scheme (TCEDS—SR) is presented. The optimum TCEDS—SR structure can be found in a practical manner with minimal simulation runs. Furthermore, the RSM allows the interactions between variables to be identified and quantified. The separation of close boiling point mixtures and azeotropic mixtures was examined to test the proposed method. The predictions agreed well with the results of a rigorous simulation. The results showed that a retrofit of the extractive distillation sequence to TCED—SR can achieve significant energy savings compared to the conventional extractive distillation sequence. © 2012 American Institute of Chemical Engineers AIChE J, 59: 1175–1182, 2013
