摘要(Abstract)：

为了解决乙酸乙酯生产过程中转化率低的问题，提出渗透汽化-酯化反应耦合技术。首先利用Aspen Custom Modeler (ACM)软件建立内置式连续性渗化膜反应器(PVMR)模型并进行验证，然后利用Aspen Plus考察反应温度、进料酸醇比、膜面积与反应液体积比对PVMR过程性能的影响。结果表明，乙醇转化率增量与反应温度之间呈正相关性；随着进料酸醇比增大，乙醇转化率增量呈先增大后减小趋势；增加膜面积与反应液体积比能促进PVMR性能。在反应温度90 ℃，进料酸醇比为2，膜面积与反应液体积比为100 m^-1时，PVMR过程乙醇转化率为82.4%。研究结果为PVMR生产乙酸乙酯节能集成工艺开发提供基础和参考。
