摘要:  利用Aspen Plus化工模拟流程软件对甲苯-乙醇共沸体系进行了萃取精馏模拟分离研究。应用Flash 2模块来筛选出萃取精馏的适宜溶剂为正丁苯。确定了萃取精馏的工艺流程,并且通过灵敏度分析模块分别考查了萃取精馏塔和溶剂回收塔的进料板位置、回流比以及溶剂比对分离效果的影响。当溶剂质量比为2.2时,产品乙醇的质量分数可达99.9%,甲苯可达99.5%,溶剂回收率约为99.5%

Abstract: Toluene-ethanol azeotropic system was separated of the simulation and studied using Aspen Plus chemical simulation software. Butyl benzene was selected as suitable solvent for extractive distillation applying Flash 2 module. Process of extractive distillation was confirmed, and feed plate location, reflux ratio and solvent ratio of extractive distillation tower and solvent recovery tower on separation effect were researched using sensitivity analysis module. When the solvent ratio was 2.2, the product of ethanol mass fractiont is 99.9%, and toluene is 99.5%, solvent recovery rate is approximately 99.5%.
