蒸汽渗透法是一种膜法气相脱水技术，与渗透汽化不同，在该过程中，进料的蒸汽与膜直接接触，在高于料液沸点的温度下进行操作，可以采用提高压力和温度等手段提高分离膜的透过通量，并可以与分馏过程集成使用，简化化工操作单元，要求所使用的膜具有更好的高温耐溶剂性能文章综述近几年２５篇有关文献，介绍蒸汽渗透过程的特点、与渗透汽化的对比、使用的膜以及其应用前景
Steam infiltration method is a membrane method gas phase dehydration technology, and pervaporation is different, in the process, the feed steam and the membrane in direct contact with the boiling point higher than the liquid temperature operation, you can use to improve the pressure and temperature Means to improve the permeate flux of the separation membrane, and can be integrated with the fractionation process to simplify the chemical unit, requiring the use of the film has better high temperature solvent resistance Article review 25 in recent years, the literature describes the steam infiltration The characteristics of the process, the comparison with pervaporation, the membranes used and their prospects of application
