评估了微孔聚丙烯中空纤维在分离水中挥发性有机化合物（VOCs）方面的应用。水被泵入纤维的内腔，有机自由空气被逆流泵入纤维的外部。VOC去除率是基于已知的经验关联式建模的，实验数据与理论预测进行了比较。在气提过程中使用膜比传统的填料膜有几个潜在的优势- 塔式曝气，包括更高的总传质系数（KLa），减少KLa对气体流速的依赖性，对可使用的气体流速没有上限，无需除雾，无需高层结构。包括25个参考文献、图表和表格。

The use of microporous polypropylene hollow fibers for separating volatile organic chemicals (VOCs) from water was evaluated. The water was pumped through the lumen of the fibers, and organic-free air was pumped countercurrently on the outside of the fibers. The rate of VOC removal was modeled on the basis of known empirical correlations, and the experimental data compared favorably with theoretical predictions. The use of a membrane in the air-stripping process offers several potential advantages over conventional packed-tower aeration, including a higher overall mass transfer coefficient (KLa), a reduced dependence of KLa on gas flow rate, no upper limit on the gas flow rate that can be used, no need for mist elimination, and no need for tall structures.
