Simulation of Isopropanol-Water Azeotrope with Continuous Extractive Distillation Process
摘要
Abstract
This paper simulates and optimizes the continuous extractive distillation process for isopropanol-water azeotropic system by using Aspen Plus V7.3. By the pseudo-binary phase diagram,DMSO is selected as a suitable extractant. The process of continuous extractive distillation with two columns is confirmed. The optimal technological scheme is obtained by sensitivity analysis tool of Aspen Plus V7.3,as follows: with 100kmol/h of isopropanol-water azeotropic solution,the number of theory stages is 23,the mixture feed stage is 17st,the solvent feed stage is 3rd, the reflux ratio is 2.4,and the solvent ratio is 1.6. Under the technological condition: the separation effect of iso-propanol is up to 99.80%,the purity of water of the extractant-recovery column is 99.58%; Cyclic supplementation of DMSO is 0.0288 kmol/h,and the recovery rate of triglycol is up to 99.982%. The results are useful for the design and operation of continuous extractive distillation process for isopropanol-water azeotropic system.关键词
