Abstract

Liquid-liquid extraction and membrane separation are well-known separation method of extensive industrial application. Their incorporation into liquid membranes has the potential of several advantages, some of which are of particular interest for the recovery of carboxylic and amino acids: selectivities higher than those attainable by current separation methods, saving on energy costs for final concentration of separated products, high fluxes, compact installation, and low capital and operation costs. Stability of the liquid advantages, can be secured by utilizing extractant blocking polymeric membranes, Applicability, process consideration, and economic implications for recovery for carboxylic and amino acids by various extractant/membrane combinations are discussed.

摘要

液-液萃取和膜分离是广泛应用于工业的知名分离方法。将它们合并到液膜中具有多种优势，其中一些对于回收羧酸和氨基酸特别有吸引力：选择性高于当前分离方法所能达到的水平，节省最终浓缩分离产物的能源成本，通量高，设备紧凑，资本和运营成本低。通过利用萃取剂阻隔聚合物膜可以确保液膜的稳定性。本文讨论了各种萃取剂/膜组合回收羧酸和氨基酸的适用性、工艺考虑因素和经济意义。
