在石化工业中，通过石蜡的蒸汽裂解，然后反复压缩和蒸馏以分离复杂的蒸气混合物来生产烯烃。第二步被认为是一个高度能源密集的过程，并且已经对可能的替代方案进行了广泛的研究。由于其较低的操作和资本成本，膜作为烯烃/石蜡分离的新方法的使用一直是研究的焦点。本文对聚合物膜在轻质烯烃/石蜡分离中的应用进行了全面的综述。它涵盖了从传统聚合物到更先进的膜材料（例如聚酰亚胺和共聚酰亚胺膜）的所有类型的膜材料。详细总结和讨论了所有聚合物膜的渗透和分离特性。 (C) 2011 Elsevier B.V. 保留所有权利。
Olefins are produced in the petrochemical industry by steam cracking of parrafins, followed by repeated compression and distillation to separate the complex vapour mixtures. The second step is considered to be a highly energy-intensive process and have been extensively studied for possible replacements. The use of membranes has been the focal point of research as a new means of olefin/paraffin separation due to its lower operating and capital costs. In this article, a comprehensive review is presented for the application of polymeric membranes in light olefin/paraffin separation. It covers all types of membrane materials starting from the conventional polymers to more advanced ones such as polyimide and copolyimide membranes. Permeation and separation characteristics of all polymeric membranes are summarized and discussed in great details. (C) 2011 Elsevier B.V. All rights reserved.
