摘要
In this study, a reactive distillation column in which chemical reaction and separation occur simultaneously is applied for the synthesis of tert-amyl ethyl ether （TAEE） from ethanol （EtOH） and tert-amyl alcohol （TAA）. Pervaporation, an efficient membrane separation technique, is integrated with the reactive distillation for enhancing the efficiency of TAEE production. A user-defined Fortran subroutine of a pervaporation unit is developed, allowing the design and simulation of the hybrid process of reactive distillation and pervaporation in Aspen Plus simulator. The performance of such a hybrid process is analyzed and the results indicate that the integration of the reactive distillation with the pervaporation increases the conversion of TAA and the purity of TAEE product, compared with the conventional reactive distillation.
在这研究，化学反应和分离同时在发生的反应蒸馏柱被申请从乙醇(EtOH ) 和 tert 戊基酒精(TAA ) 的 tert 戊基乙醇醚(TAEE ) 的合成。Pervaporation，一种有效的膜分离技术，随为提高 TAEE 的效率的反应蒸馏是综合的生产。一个 pervaporation 单位的一个自定义 Fortran 子程序被开发，允许在白杨正模拟器的反应蒸馏和 pervaporation 的混杂流程的设计和模拟。如此的混杂流程的表演被分析，结果显示 pervaporation 增加的反应蒸馏 witfi 的集成 TAA 和 TAEE 产品的纯净的变换，与常规反应蒸馏相比。
