Recent advances in pervaporation hollow fibermembranes for dehydration of organics

tPervaporation (PV) has been potentially identified as a candidate in replacing the conven-tional distillation since it possesses the ability to separate azeotropic solvent mixtures. Ata large scale, PV has been mainly involved within hybrid processes for the dehydration oforganics toward their purification. Considering that the membrane is the primary separationbarrier, "membranologists" are currently seeking for suitable membranes that can be effec-tive for industrial applications. In this regard, due to its minimal fouling and large effectivesurface area, hollow fiber configuration is recognized as the most advantageous geome-try in comparison with flat sheet or tubular modules. Therefore, the goal of this reviewpaper is to provide an outlook on the studies available so far focusing on the use of hollowfiber membranes for the dehydration of organics by PV. By fully reviewing the literature,the main attention is paid to such works that release relevant insights into new membraneconcepts and their performance, together with some brief fundamentals of PV technology.The concluding remarks, future trends and recommendations to the new researchers arealso given.
