Fabrication of Crosslinkable Hollow Fiber Membranes for Pervaporation Dehydration
Integrally-skinned asymmetric Polyetherimide/Poly (vinyl alcohol) (PEI/PVA) hollow fber membranes for pervaporation dehydration were fabricated by non-solvent induced phase inversion. PVA inside the PEI matrix could be crosslinked to provide membrane performance stability during long term operation. The effects of different PEI/PVA blend ratio, external coagulant type and...
متن کاملPervaporation Membranes for Biobutanol Production
Because of the emerging scarcity of oil resources and the demand for environmental protection, as a typical biofuel, biobutanol produced by biomass fermentation is critical for the development of renewable energy. Pervaporation is considered to be an attractive separation technology for both the recovery of butanol from fermentation broth and the dehydration of butanol from low-water content so...
متن کاملElectrostatic interactions of asymmetrically charged membranes
We predict the nature (attractive or repulsive) and range (exponentially screened or long-range power law) of the electrostatic interactions of oppositely charged, planar plates as a function of the salt concentration and surface charge densities (whose absolute magnitudes are not necessarily equal). An analytical expression for the crossover between attractive and repulsive pressure is obtaine...
متن کاملThe Isolation of Organic Compounds using Organophilic Pervaporation Membranes
Organophilic membranes provide a method of recovering organic compounds by pervaporation, which exploits the selective transport of the organic phase. The main application is in the extraction of bio-alcohols from aqueous solution. The effect of membrane composition on performance in transporting alcohols and not water at improved rates is the focus of this review. In th...
متن کاملManipulation of confined structure in alcohol-permselective pervaporation membranes
Article history: Received 14 December 2016 Received in revised form 12 May 2017 Accepted 14 May 2017 Available online 1 July 2017 Alcohol-permselectivity pervaporation has been arousing increasingly more attention in bioalcohol production due to the advantages of environmental friendliness, low energy consumption and easy coupling with fermentation process. With the intrinsic feature of larger ...
