| 摘 要： | 采用经验法与UNIFAC基团贡献法估算相结合,对一系列的溶剂进行了筛选.并根据筛选得的溶剂进行了萃取精馏实验,实验表明了采用萃取精馏分离的可行性.通过模型参数对萃取精馏与减压精馏进行了逐板计算,其计算结果与减压15 kPa(绝对压)条件下所需要的理论塔板数相当.

| Abstract: | Using the experience of law and the UNIFAC group contribution method to estimate the combination of a series of solvents were screened.And in accordance with a screening of the extractive distillation solvent for the experiments showed that the use of the feasibility of extractive distillation separation.Model parameters through the extractive distillation and vacuum distillation were calculated for each plate.Under the same conditions,the number of theoretical plates of the extractive distillation was appr... |
