Polymers are unarguably the most broadly used membrane materials for molecular separations and beyond. Motivated by the commercial success of membrane‐based desalination and permanent gas separations, glassy polymer membranes are increasingly being studied for hydrocarbon separations. They represent a class of challenging yet economically impactful bulk separations extensively practiced in the refining and petrochemical industry. This review discusses recent developments in membrane‐based hydrocarbon separations using glassy polymer membranes relying on the sorption‐diffusion mechanism. Hydrocarbon separations by both diffusion‐selective and sorption‐selective glassy polymer membranes are considered. Opinions on the likelihoods of large‐scale implementation are provided for selected hydrocarbon pairs. Finally, a discussion of the challenges and outlook of glassy polymer membrane‐based hydrocarbon separations is presented.

通过玻璃状聚合物膜分离烃

毫无疑问，聚合物是最广泛用于分子分离的膜材料。由于基于膜的脱盐和永久性气体分离的商业成功，越来越多的玻璃态聚合物膜被用于烃类分离的研究。它们代表了在炼油和石化行业广泛实践的一类具有挑战性但对经济有影响的散装分离。这篇综述讨论了依靠吸附-扩散机理的使用玻璃态聚合物膜的基于膜的烃分离的最新进展。考虑通过扩散选择性和吸附选择性玻璃态聚合物膜进行烃分离。对于选定的碳氢化合物对，提供了关于大规模实施可能性的意见。最后，
