“…Water flux also increased slightly from 330.8 to 353.3 g/m 2 h, while the separation factor showed a slight fluctuation between 33.2 (5 g/L) and 35.8 (15 g/L). PSI increased with increasing feed concentration, in accordance with the prediction by Maxwell–Stefan model 44 . The highest PSI of 21.85 kg/m 2 h was attained with 25 g/L feed butanol.…”

In this study, spray-coating was used to prepare dihydroxypolydimethylsiloxane (PDMS) composite membranes with high flux and separation factor for biobutanol recovery from aqueous solution. A thin, smooth, and defect-free PDMS layer was prepared by spray-coating on polyvinylidene difluoride ultrafiltration membrane with little PDMS penetration. The effects of process parameters for membrane fabrication and pervaporation on membrane performance were investigated. A membrane with 2 μm active layer was obtained with a high flux of 1306.9 g/m 2 h. The optimal membrane with the highest pervaporation separation index (PSI) (19.15 kg/m 2 h) showed a total flux of 530.6 g/m 2 h and a separation factor of 36.1 at 37 C, and a PSI of 65.61 kg/m 2 h and a flux of 1927.0 g/m 2 h at 70 C. Membrane performance was affected by feed composition and temperature. Acetone-butanol-ethanol solution and fermentation broth gave lower butanol fluxes and separation factors compared to butanol model solution.

“…In another work, the mass transfer through a PDMS commercial membrane for pervaporation separation of the butanol from aqueous solution has been studied by Ebneyamini et al [126]. A semiempirical approach on the Maxwell-Stefan model was extended to consider the effect of membrane swelling and the operating temperature on the diffusion coefficient and sorption properties.…”

Pervaporation is a suitable technique for butanol recovery from aqueous solutions especially ABE fermentation broths. The performance of the membrane, in terms of permeation flux and modelling of the mass transfer through membranes provides a deeper understanding, which may assist to orient the research and the development of pervaporation processes. Modelling of the mass transport through the membrane is based on sorption and diffusion of the components into and across the membrane. In this study, an overview of the different models used for the pervaporation separation of butanol is presented. Up to now, the solutiondiffusion based models were the main methods used and the Maxwell-Stefan theory was very limited. In addition, to our knowledge, the pore-flow model was not applied for the modelling of butanol pervaporation separation. Moreover, the Maxwell-Stefan theory seems to be the most accurate mass transfer model to be used for the pervaporation separation method in comparison to the other models.

“…Among the models used to describe the membrane -assisted separation, Maxwell-Stefan theory has been shown practical to describe and predict the diffusion of multicomponent mixtures. The theory relies on irreversible thermodynamics, giving relationship between the driving force and the frictional resistances [29,33,34]. Maxwell-Stefan models have successfully been applied in analysis of pervaporation fluxes to describe multicomponent diffusion through various types of membranes [29,[34][35][36][37][38].…”
