Special Issue Information

Dear Colleagues,

Polymeric hollow fiber membranes have become exceedingly important in different fields of application, including waste-water treatment, desalination, gas separation, pervaporation, agriculture, medicine, tissue engineering, etc. A number of research and development projects have been carried out by researchers in industry and academia, as well as in government sectors since its invention during the 1960s. In the initial stage, although the development of hollow fiber membranes is primarily focused on reverse osmosis desalination applications, commercial implementation in other fields has been well established and the hollow fiber membrane markets now exceeds a billion dollars annually. The aim of this Special Issue is to capture the recent scientific and technological advances in the development of polymeric hollow fiber membranes (PHFMs), and their potential applications. The Special Issue will also seriously consider the challenges and future research directions.

Considering your extensive knowledge and experience in polymeric hollow fiber membranes, I would like to invite you to contribute original research articles, as well as review articles, to this Special Issue, which will increase the basic and cutting-edge subject knowledge on hollow fibers and may lead to the development of new technologies and innovations for their efficient and economic utilization. I am particularly interested in articles describing theoretical and experimental works related to PHFMs and their applications. Review articles on recent developments, in terms of fabrication and applications of these materials, are also welcome.

Only nonwetted porous membranes can be used in membrane distillation. The possibility of application in this process the capillary polypropylene membranes manufactured by thermally-induced phase separation was studied. The performance of a few types of membranes available commercially was presented. The resistance of the membranes to wetting was tested in the continuous process of water desalination. These studies were carried out for 1000 h without module cleaning. The presence of scaling layer on the membranes surface was confirmed by Scanning Electron Microscope observations. Both the permeate flux and distillate conductivity were almost not varied after the studied period of time, what indicates that the used membranes maintained their nonwettability, and the negative influence of scaling was limited. The role of surface porosity on the pore wetting and influence of membrane wettability on the quality of the distillate obtained were discussed. Full article

Membrane separation for helium extraction from natural gas gained increased interest recently. Several vendors offer membrane elements for helium extraction, although data on their performance and operating experience are unpublished. The aim of this work was to obtain and study the separation performance of asymmetric hollow-fiber membrane element from commercial polyamide-imide Torlon®, in conditions close to the industrial process of helium extraction from natural gas. A membrane element with an active area of 0.177 m2, a helium permeance of 100 l(STP)/(m2·h·bar), and a selectivity α(He/CH4) = 340 was produced. This corresponds to a selective layer thickness of 82.3 nm, which was confirmed by SEM and resistance model calculations. The obtained membrane element was employed to decrease the concentration of helium in its binary mixture with methane from 0.4% to 0.05%. A relationship of separation characteristics from transmembrane pressure is also presented. At 70 bar and a stage cut of 2.7%, the feed flow rate was 0.16 m3(STP)/h, which yielded a helium permeate concentration of 14.7%. At 80 bar, a decrease in permeance to 60 l(STP)/(m2·h·bar) and in selectivity to 240 was observed. It was shown that the main reason for aging was the increased support resistance, due to a partial compaction of pores with a radius of less than 15 nm. Full article

Gas-liquid membrane contactors that were based on hollow fiber membranes are the example of highly effective hybrid separation processes in the field of membrane technology. Membranes provide a fixed and well-determined interface for gas/liquid mass transfer without dispensing one phase into another while their structure (hollow fiber) offers very large surface area per apparatus volume resulted in the compactness and modularity of separation equipment. In many cases, stated benefits are complemented with high separation selectivity typical for absorption technology. Since hollow fiber membrane contactors are agreed to be one of the most perspective methods for CO2 capture technologies, the major reviews are devoted to research activities within this field. This review is focused on the research works carried out so far on the applications of membrane contactors for other gas-liquid separation tasks, such as water deoxygenation/ozonation, air humidity control, ethylene/ethane separation, etc. A wide range of materials, membranes, and liquid solvents for membrane contactor processes are considered. Special attention is given to current studies on the capture of acid gases (H2S, SO2) from different mixtures. The examples of pilot-scale and semi-industrial implementation of membrane contactors are given. Full article
