摘要

为实现乙醇-水的高效分离，研究了混合蒸馏-渗透蒸发工艺。首先，在Aspen Custom Modeler中开发数学模型。然后，设计了四种节能配置：蒸馏-渗透蒸发（D-PV）、热泵辅助蒸馏-渗透蒸发（HPD-PV）、热泵-热集成辅助蒸馏-渗透蒸发（HPD-HENs-PV）和改性乙醇质量分数蒸馏-渗透蒸发（ZHPD-HENs-PV）。采用多目标遗传算法进行优化。结果表明，与共沸蒸馏（AD）相比，这些工艺的总能耗（TEC）显著降低，年总成本（TAC）也大幅降低。

Distillation-Pervaporation Hybrid Process for Ethanol Dehydration: Process Optimization and Economic Evaluation

To achieve energy-efficient ethanol-water separation, a hybrid distillation-pervaporation process was investigated. First, a mathematical model was developed in Aspen Custom Modeler. Then, four energy-saving configurations were designed: distillation-pervaporation (D-PV), heat pump-assisted distillation-pervaporation (HPD-PV), heat pump-heat integration-assisted distillation-pervaporation (HPD-HENs-PV), and modified ethanol mass fraction distillation-pervaporation (ZHPD-HENs-PV). A multiobjective genetic algorithm was applied for optimization. The results demonstrated that compared to azeotropic distillation (AD), the total energy consumption (TEC) of these processes was significantly reduced, while the total annual cost (TAC) was also substantially decreased.
