Small Grants for Exploratory Research: Separation and Dehydration of Organic Compounds by Vapor Permeation

该项目研究了蒸汽渗透在有机化合物脱水或有机化合物混合物分离中的应用。将建立一个仪器来研究蒸汽渗透机制，确定几个操作变量（进料成分、渗透和保留压力以及温度）的影响，并将该方法与可比条件下的渗透蒸发进行比较。膜材料包括聚乙烯醇-聚丙烯腈复合材料。将研究异丁烯/水和醋酸水混合物的分离，因为它们具有科学和重大的工业利益。研究结果将引导经济、节能分离技术的发展。

The project examine the use of vapor permeation for dehydration of organic compounds or for separations of mixtures of organic compounds. An apparatus will be built for studying vapor permeation mechanisms determine the effects of several operating variables (feed composition, permeate and retentate pressures, and temperature), and compare the method to pervaporation under comparable conditions. Membrane materials include poly (vinyl alcohol) - poly (acrylonitrile) composites. Separation of mixtures of isobutylene/water and acetic acid water will be studied, because they are of scientific and substantial industrial interest. The results should lead to development of economic and energy saving separation technologies.
