Hydrophobic pervaporation: influence of the support layer of composite membranes on the mass transfer

Mass transport of aliphatic alcohols and esters through hydrophobic pervaporation membranes

“…The molecular weight of the polymer repeat unit, M pol , and POMS density, ρ pol , were obtained from literature data [30]. The surface porosity, ε s , and the pore diameter, d pore , of the support materials were obtained from the literature [31].…”

Pervaporation performance analysis and prediction—using a hybrid solution-diffusion and pore-flow model

“…The resistance of the supporting porous layer is normally neglected. However, Lipnizki et al (2002) indicated that the overall mass transfer resistance depends on both physical and chemical properties of the supporting layer and the resistance of the supporting layer can have a significant impact on the total flux and selectivity. Recently, Jiraratananon et al (2002aJiraratananon et al ( , 2002b) used a complete model based on the solution-diffusion model for pervaporation, which utilize the resistance-in-series concept to include the mass transfer resistance of upstream feed liquid film and the vapor permeation resistance in the supporting porous membrane layer.…”

Application of thin film composite membranes to the membrane aromatic recovery system

“…The influence of the support resistance on K OV has rarely been investigated, especially for liquids [6][7][8]. In this study, the fluid inside the pores of the composite membrane support is a liquid, so it is expected that the support resistance will be of greater importance than for gaseous transport.…”
