摘要
精细化工生产中存在产品浓缩纯化、溶剂回收和催化剂回收等分离工序,其操作费用占生产成本比重较高.有机溶剂纳滤(OSN)可替代或耦合精馏等传统工艺以节约大量生产成本,符合“双碳”战略,对精细化工的绿色发展具有重要意义.本文综述了近年来OSN在制药工程、食品加工、均相催化等精细化工领域的应用案例,针对不同分离任务讨论了传统分离工艺的不足和OSN的优势,介绍了各领域的典型OSN工艺流程,商业及高性能实验室自制膜的研发进展,分析了当前OSN应用研究所面临的难题及未来的发展方向.
In fine chemical engineering, the operating and equipment investment costs from product concentration and purification, solvent recovery, catalyst recovery and so on, account for a high proportion of production costs. To significantly reduce the production cost, the newly developed organic solvent nanofiltration(OSN) can replace or couple distillation and other traditional processes, which is of great significance to the development of green technology in fine chemical engineering. This article reviewed the application and research progress of OSN in fine chemical engineering, including pharmaceutical industry, food engineering, recovery of homogeneous catalyst. The disadvantages of traditional separation processes and the obvious advantages of OSN were discussed for different separation tasks in each field. The typical OSN process and separation performance of commercial and laboratory self-made membranes were introduced. The problems faced by the OSN application research and the development prospect were analyzed.
