摘要
有机溶剂纳滤(OSN)是一种用于高效分离相对分子质量为200~1000的溶质和有机溶剂的新型膜分离技术。相比传统分离技术,OSN具有能耗低、污染少和分离效率高等突出优势.因此,OSN在石油化工中的溶剂回收、含油废水处理、油品纯化等方面得到了广泛应用.本文综述了近年来OSN膜分离技术在石油化工领域的应用及研究进展,包括典型膜分离工艺流程、膜选择与设计开发、膜分离性能等,分析了OSN所面临的挑战,并对未来的发展前景进行展望.
Organic solvent nanofiltration(OSN),a new membrane separation technology,is used for efficient separation of solute with molecular weight of 200~1000 from organic solvents.Compared with traditional separation technology,OSN has advantages of low energy consumption,less pollution,and high separation efficiency.Therefore,OSN has been widely used in petrochemical industry,such as solvent recovery,oil waste water treatment,and oil purification,etc.In this work,the recent applications and research progress of OSN membrane separation technology in petrochemical field were reviewed including,typical membrane separation processes,the selection and design development of membrane,separation performance of membrane,etc.The challenges faced by OSN and the future development prospects were also analyzed and anticipated.
