This study reports the analysis and design of a liquid phase esterification process to convert acetic acid with isoamyl alcohol into acetate via reactive pervaporation, in presence an Amberlite IR-120 ion exchange resin catalyst. To accomplish this, catalytic reactor is coupled separation membrane unit (Pervaporation Membrane Reactor (PVMR)). In proposed unit, chemical reaction equilibrium favo...

Lignin, a biomass material, is employed as the effective material for building up separative layer of thin-film composite membranes pervaporation desalination.

A graphene oxide (GO) membrane is supported on a ceramic hollow fiber prepared by a vacuum suction method. This GO membrane exhibited excellent water permeation for dimethyl carbonate/water mixtures through a pervaporation process. At 25 °C and 2.6 wt % feed water content, the permeate water content reached 95.2 wt% with a high permeation flux (1702 g m(-2) h(-1)).

the effects of operating parameters such as feed temperature and permeate-side pressure on the performance of a commercial pva membrane in the dehydration of toluene by a pervaporation (pv) membrane system is studied in the present work. the results obtained indicate that increasing temperature in the range of 40 to 70 °c and reducing permeate pressure in the range of 1 to 10 mmhg increase memb...

Recent advances in membrane-based separations include chiral separations, nanofiltration, ion-permselectivity, gas separation and pervaporation. Novel chiral separations using enzymes and chiral surfactants as carrier have been achieved using facilitated-transport membranes. Graft-copolymeric membranes have been constructed that possess pH-controlled ion selectivity, and membranes have been mad...

BACKGROUND Butanol is regarded as an advanced biofuel that can be derived from renewable biomass. However, the main challenge for microbial butanol production is low butanol titer, yield and productivity, leading to intensive energy consumption in product recovery. Various alternative separation technologies such as extraction, adsorption and gas stripping, etc., could be integrated with aceton...

Hybrid separation systems have recently been hailed as one of the inost promising alternatives to conventional capital and energy intensive separation processes. Hybrid separation systems are able to effectively separate inixtures commonly encountered in the fine chemical and pharmaceutical industries that are difficult or impossible to separate by conventional distillation processes due to aze...
