摘要
针对醇解废液回收能耗高的问题,采用Aspen Plus化工流程模拟软件对共沸精馏塔TQ-501进行了模拟。在选取合适的热力学模型NRTL基础上,分别进行了单因素和多因素分析,得出了最佳操作参数组合:理论板数27、进料位置7、回流比1.55、馏出比0.341。最后,在回流比发生变化的情况下,对TQ-501塔进行了灵敏板分析,得出TQ-501塔第12块板为最佳灵敏板。
Large amounts of energy are needed in the recycling of the waste alcoholysis liquid produced during the manufacture of polyvinyl alcohol.An azeotropic distillation column TQ-501 has been simulated using the chemical process simulation software Aspen Plus to solve the above problem.Based on selecting appropriate thermodynamic non-random two-liquid（NRTL） models,the following optimum combination of operating parameters were obtained by univariate and multivariate analysis： number of theoretical plates 27,feed location 7,reflux ratio 1.55,distillate to feed ratio 0.341.Finally,when the reflux ratio was changed,the 12th plate was determined to be the sensitive plate.
