Abstract Fatty acids (FAs) are a very important group of raw materials for chemical industry, and the technology of separating or purifying the FAs from the reaction product mixture has always been the hotspot of research. Membrane processes for separation of FAs are being increasingly reported. Compared with conventional FAs separation methods, membrane separation has the advantages of low energy consumption, system compactness, high separation efficiency, easy scale-up, high available surface area per unit volume and low working temperatures, thereby attracting considerable attention of many researchers. In this regards, this paper critically reviewed the developments of methods for FAs separation and purification, and the future prospects of coupling membrane technology with hydrolysis for enhanced production of FAs.
