摘要:
精油及其挥发性组分在化妆品、食品和药品工业、农业及食品保鲜等领域有着广泛的应用潜力。目前挥发性精油的分离主要采用的是分段蒸馏技术,该技术存在成本高、能耗大且容易造成精油组分破坏等缺陷,因此其应用受到了极大的限制。渗透汽化(pervaporation,PV)是一种用于液体混合物分离的新型膜分离技术,具有高效节能、环境友好和容易操作等优点,特别是能够实现热敏性物质的高效单级分离,因此在挥发性精油的分离和挥发性芳香化合物组分精制等方面具有巨大的应用潜力。本文系统总结了渗透汽化技术在挥发性精油分离领域的最新进展,综述了用于分离挥发性精油的渗透汽化膜材料、分离工艺及其应用现状,并对渗透汽化用于大规模分离挥发性精油过程中面临的挑战进行了讨论。
