“…The contact angle of a water drop on a dry membrane surface sample was found to be 110°and 112°for the Pervap 4060 and Pervatech PDMS membrane, respectively, which is a typical value observed for PDMS-based membranes (Chovau et al, 2010), and indicates a high hydrophobicity degree.…”

a b s t r a c tPervaporation is claimed to be a promising separation technique for the purification of ethanol from fermentation broths during bio-ethanol production. In this study, influence of fermentation by-products on the purification of ethanol from water during hydrophobic pervaporation was investigated.Sugars and salts were found to increase the membrane performance. Reason for this was a change in vapor/liquid equilibrium. 2,3-Butanediol decreased the ethanol flux and selectivity factor, while glycerol exhibited no effect. This was explained by a strong sorption of butanediol into PDMS and no sorption of glycerol. Due to the presence of carboxylic acids, hydrophobicity degree of the Pervap 4060 membrane decreased, which resulted in an irreversible increase in water flux and decrease in separation performance. These observations suggested the presence of silicalite-based fillers in the membrane. When the pH was raised to a value above the dissociation constant, no changes in hydrophobicity degree and membrane performance were found.

“…The PV processes reported are the recovery of volatile organic compounds, such as 1,1,1–trichloroethane (TCA) and trichloroethylene (TCE), and the removal of toluene and ethanol from diluted aqueous solutions. The obtained results are compared in terms of selectivity and flux with commercial membranes with particular emphasis on the performance and on the nanostructures 23–26…”

The preparation and characterization of new, tailor-made polymeric membranes using poly(styrene-b -butadiene-b -styrene) (SBS) triblock copolymers for gas separation are reported. Structural differences in the copolymer membranes, obtained by manipulation of the self-assembly of the block copolymers in solution, are characterized using atomic force microscopy, transmission electron microscopy, and the transport properties of three gases (CO 2 , N 2 , and CH 4 ). The CH 4 /N 2 ideal selectivity of 7.2, the highest value ever reported for block copolymers, with CH 4 permeability of 41 Barrer, is obtained with a membrane containing the higher amount of polybutadiene (79 wt%) and characterized by a hexagonal array of columnar polystyrene cylinders normal to the membrane surface. Membranes with such a high separation factor are able to ease the exploitation of natural gas with high N 2 content. The CO 2 /N 2 ideal selectivity of 50, coupled with a CO 2 permeability of 289 Barrer, makes SBS a good candidate for the preparation of membranes for the post-combustion capture of carbon dioxide.
