Performance of a nanofiltration membrane for removal of ethanol from aqueous solutions by pervaporation

Performance of PDMS membranes in pervaporation: Effect of silicalite fillers and comparison with SBS membranes

“…The dead-end pervaporation unit used in the experiments is described elsewhere [7]. During pervaporation, vacuum was applied on the permeate side and maintained constant (1 mbar) to ensure driving force for the separation.…”

“…Among them the most studied process is pervaporation with hydrophilic membranes, which involves either dehydration of organic compounds or water extraction from a mixture [2][3][4]. On the other hand, hydrophobic pervaporation could be of potential use in the industry, as an easy and economical method of either organic solvents recovery, removal of alcohol form alcoholic beverages, or recovery of aroma compounds from fruit juices [5][6][7][8]. Typical applications of organophilic pervaporation include separation of organic compounds mixtures, such as benzene/cyclohexane and methanol/methyltert-butyl ether (MTBE) [9,10].…”

Recent Advances in Techniques for Flavor Recovery in Liquid Food Processing

“…This technique can be an alternative to conventional separation processes such as steam distillation, liquid solvent extraction, and vacuum distillation and has been successfully applied during the last years, for recovery of aroma compounds from fruits and fruit juices [11,39,47,70,73,78] and subsequent addition to the same juice after concentration by evaporation [41,51,92]. Pervaporation technique has also been applied for ethanol removal over the last few years [18,97,102] and aroma recovery from alcoholic beverages [14,17,19,50]. The most recent studies for the application of this technique, conducted by different researchers in food industry, are summarized in Table 1.…”

Pervaporation performance of unfilled and filled PDMS membranes and novel SBS membranes for the removal of toluene from diluted aqueous solutions

“…These operation conditions can be decoupled from permeant-specific intrinsic membrane properties by the use of permeabilities and selectivities as suggested by Wijmans [42]. In this way, the contribution by nature of the membrane to the separation performance can be clarified and quantified as done by Verhoef et al [43].…”
