The combination of a new PERVAPTM membrane and molecular sieves enhances the ethanol drying process

Modeling and simulation of pervaporation (PV) separation for alcohol dehydration

“…These composite membranes consist of poly (vinyl alcohol) (PVA) as a thin selective layer with a different degree of cross-linking and different thicknesses, cast on an asymmetric porous polyacrylonitrile (PAN) membrane as a support layer and coated onto a nonwoven fabric layer. The membrane characterization was described in our previous work [ 31 ].…”

“…The setup of the PV process for this study was described in our previous work and had an effective membrane area of 100.2 cm 2 [ 31 ]. The alcohol-water mixture was circulated across the membrane surface at a flow rate of 1.6 L/min.…”

A Review on the Separation of Volatile Organic Compounds from Wastewater by Pervaporation Processes

“…A bioreactor or reactor can additionally attach hydrophilic membranes to remove water produced as a byproduct [57][58][59][60][61]. Other research investigated the combination of PV and molecular sieves to enhance the ethanol drying process [62].…”

Polydimethylsiloxane (PDMS) Membrane for Separation of Soluble Toluene by Pervaporation Process

“…Extensive testing of PV is being performed on systems that are challenging for current separation techniques, such as distillation, adsorption, and extraction. As a matter of fact, PV is a strong contender for the separation of azeotropic and close-boiling liquids, heat-sensitive materials, and organic mixtures, as well as the removal of diluted volatile organic compounds (VOCs) from wastewater and the recovery of volatile aroma compounds from fruit juices [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ].…”
