Abstract

Membrane technology holds significant potential for augmenting or partially substituting conventional separation techniques, such as heat-driven distillation, thereby reducing energy consumption. Organic solvent nanofiltration represents an advanced membrane separation technology capable of discerning molecules within a molecular weight range of approximately 100–1000 Da in organic solvents, offering low energy requirements and minimal carbon footprints. Molecular separation in non-polar solvent system, such as toluene, n-hexane, and n-heptane, has gained paramount importance due to their extensive use in the pharmaceutical, biochemical, and petrochemical industries. In this review, we presented recent advancements in membrane materials, membrane fabrication techniques and their promising applications for separation in non-polar solvent system, encompassing hydrocarbon separation, bioactive molecule purification and organic solvent recovery. Furthermore, this review highlighted the challenges and opportunities associated with membrane scale-up strategies and the direct translation of this promising technology into industrial applications.

用于非极性溶剂系统分离的有机溶剂纳滤膜

膜技术在增强或部分替代传统分离技术（如热驱动蒸馏），从而降低能耗方面具有巨大潜力。有机溶剂纳滤是一种先进的膜分离技术，能够分辨有机溶剂中分子量范围约为 100-1000 Da 的分子，能耗低，碳足迹最小。由于甲苯、正己烷和正庚烷等非极性溶剂体系在制药、生化和石化工业中的广泛应用，这些溶剂体系中的分子分离已变得极为重要。在这篇综述中，我们介绍了膜材料、膜制造技术的最新进展及其在非极性溶剂系统中分离的应用前景，包括碳氢化合物分离、生物活性分子纯化和有机溶剂回收。此外，本综述还强调了与膜放大战略相关的挑战和机遇，以及将这一前景广阔的技术直接转化为工业应用的问题。
