But the attempts to use the electospun nanofiber mats, also known as electro-spun nanofiber membranes (ENMs), for filtration purposes began only recently. Among many membrane filtration processes, air cleaning by the removal of dust particles has already been commercialized and the product has been in the market for some time. On the other hand, the application of ENMs for liquid separation has a much shorter history and its commercialization has not yet been achieved. Since a large number of researches are reported in the open literature each year, its commercialization looks only a matter of time. For example, many papers are now available on the pressure driven membrane separation processes such as RO, NF, UF, MF by ENMs, and as many papers have been published on the other membrane separation processes including pervaporation, membrane distillation, forward osmosis and membrane adsorption. It is needless to say that EMFs have gained popularity within a short period due to the facile fabrication, interconnectivity and large area/volume ratio. Despite these advantages, ENMs’ pore sizes are intrinsically very large (fractions of micrometer to few micrometer), which makes modification of surface chemistry and especially reduction of the ENM pore size indispensable for wider applications of ENMs for membrane separation processes.https://www.msrjournal.com/article_32402_3856623d394513cc466756a0bafd314f.pdfFIMTEC & MPRLJournal of Membrane Science and Research2476-54065220190401Techno-economic evaluation of helium recovery from natural gas; A comparison between inorganic and polymeric membrane technology1261363409910.22079/jmsr.2018.87998.1196ENMay-Britt HaggDepartment of Chemical Engineering

A membrane separation process may offer a more efficient production system with smaller footprint and lower operational cost than conventional cryogenic system. Inorganic membranes with high mechanical strength are known to exhibit good stability at high pressure. In this work, two inorganic membranes, porous silica and carbon molecular sieve (CMS) were studied by simulation for their applicability in the He recovery process and compared against a Matrimid polymeric membrane. An in-house developed membrane simulation model (Chembrane) interfaced with Aspen HYSYS was used to simulate the membrane area and energy requirement for the He separation process. He was separated directly from a mixture containing methane (CH4) and 1-5 mole% He in the feed stream, and natural gas containing 1-5 mole% of He in a mixture of CH4 and N2. These streams were considered at 70 bar pressure and 25 °C. Single and two-stage membrane separation processes with and without recycle stream were simulated to achieve 97 mole % purity and 90% recovery of He. The simulation results showed that all three membranes can achieve required purity and recovery in a two-stage separation process. However, a recycle is required while using Matrimid membrane which adds cost and complexity to the system. The highest net present value (NPV) for silica, CMS, and Matrimid membrane was $M 2.5, 2, and 1.75 respectively when 5% He is present in feed gas and 15 years of plant life is considered.https://www.msrjournal.com/article_34099_d231759c06be4a6112a569fd7b4cbf19.pdfFIMTEC & MPRLJournal of Membrane Science and Research2476-54065220190401Investigation of the Improvement of Energy Generation by Pressure Retarded Osmosis1371463282410.22079/jmsr.2018.88969.1200ENEndre NagyReseaarch Institute of Biomolecular and Chemical Engineering, University of Pannonia0000-0002-3863-4194Monika MeiczingerResearch Institure of Bio-molecular and Chemical Engineering, University of PannoniaMarta VitaiResearch Institute of Bio-molecular and Chemical Engineering, University of PannoniaJournal Article20180628<span class="fontstyle0">Knowing the overall solute flux and the partial fluxes expressed by every single transport layer, the membrane internal interface concentrations can separately be expressed.

The membrane performance can also be improved not only by its characteristic properties, but by the operating conditions as well, e.g. by applying different solute concentrations instead of seawater-river water pair. The higher draw solute or lower feed concentrations can serve then much higher power density. The knowledge of the individual interface concentration of every single transport layer enables the user to do more deep, more precise study of the mass transfer process during pressure retarded osmosis. Finally, it is shown reasonable agreement between the measured and predicted data.</span>https://www.msrjournal.com/article_32824_0dd734c3576d3658d1aba8d07a62d6e3.pdfFIMTEC & MPRLJournal of Membrane Science and Research2476-54065220190401A Study on Neodymium Recovery from Aqueous Solutions for Designing a New Generation of Sandwich Liquid Membrane1471563279910.22079/jmsr.2018.93621.1214ENPietro ArgurioDepartment of Environmental and Chemical Engineering, University of Calabria, Via P.

One of the ways to produce fluoropolymer membranes is through surface fluorination. The modifcation of commercial polymers with membrane properties, poly(4-methyl-1-pentene) (PMP) in particular, is of special interest. PMP is widely used in the creation of protective coatings in microelectronics and it is used in membrane oxygenation. This paper presents new results for the gas-phase fluorination of PMP flms with improved gas separation characteristics. The fluorination is confrmed by infrared (IR) spectroscopy.

For operating pressures up to 12 bar the permeate flux increases linearly with the pressure. Then, with the increasing pressure, they deviate from linearity and reach a limiting flux of 8.79 l/(h∙m^2∙bar) at 30 bar. The slope of the asymptotic linear variation is 0.48 l/(h∙m^2∙bar).

This paper reports on progress toward development of a comprehensive model of the complicated physical-chemical processes occurring in spiral wound membrane (SWM) modules, that accounts for the temporal system variability caused by organic membrane fouling. To render the mathematical modeling-problem tractable, justifed simplifcations (retaining the physical parameter interdependencies) lead to a system of basic equations in two spatial planar coordinates, enabling to obtain a realistic temporal evolution of all process parameters at retentate and permeate flow channels of SWM modules. The developed flexible model structure, and process simulator, allow incorporation of sub-models (for phenomena occurring at small spatial scales during desalination) that account for a) feed-spacer effects on friction losses and mass transfer and b) membrane fouling. These sub-models, in the form of generalized expressions, are obtained for the former case through advanced numerical simulations, and for the latter by correlating experimental data of specifc fouling resistance with permeation flux. Typical parametric study results presented herein, for realistic combinations of design and operating system parameters, demonstrate the versatility and reliability of the new model/simulator and its potential to analyze the complicated interaction of mechanisms involved during fouling evolution. The new results warrant further model development that would include other types of fouling and scaling, thus leading to a comprehensive simulator useful for practical applications.</span>https://www.msrjournal.com/article_33957_d5571e4b73ede565973b4403bd77ce05.pdfFIMTEC & MPRLJournal of Membrane Science and Research2476-54065220190401Enzyme-Mediated Extraction of Limonene, Linalool and Linalyl Acetate from Bergamot Peel Oil by Pervaporation1871933293710.22079/jmsr.2018.95080.1221ENFrancesco GalianoInstitute on Membrane Technology National Research Council, ITM-CNR, Via P.

Nevertheless, there are some limitations for the separation of such compounds. In this framework, pervaporation (PV) technology was proposed as a tool for the separation of limonene, linalool, and linalyl acetate from bergamot oil by using two different commercial organophilic membranes (PDMS-1070 and POMSPEI). The use of an enzymatic pre-treatment was also investigated in order to enhance the performance of selected membranes. All PV experiments were carried out at different temperatures (ranging from 25-40 ºC) in order to analyze the temperature dependence by the Arrhenius relationship. Experimental data indicated that both investigated membranes did not present signifcant differences in terms of enrichment factor, independently from the enzymatic pre-treatment (at 25 ºC). However, the enrichment factors increased signifcantly at 40°C when enzymes were applied. The experimental results clearly indicate that PV is a viable approach for the recovery of such aroma solutes from bergamot peel oils as it yields good separations under mild operating conditions. The efciency of the pervaporative process is indeed enhanced if assisted by an enzymatic treatment.</span>https://www.msrjournal.com/article_32937_d241d6ef07dd37eb7103bbcf3950be3f.pdf
