- Abstract
- Ceramic membranes are highly promising for application in organic solvent nanofiltration (OSN). Unfortunately, the governing molecular transport mechanisms are not yet fully understood. To study the importance of different transport mechanisms, we analyze transport through these membranes using Maxwell-Stefan theory. We show that the total flux is dominated by the viscous contribution, when using Poiseuille's law. Cross-coupling of the order of magnitude observed in liquids, leads to changes in reten-tion of up to 20%. Finally, it was shown that non-ideal thermodynamics in the external liquid phase can explain changes from positive to negative retention when using the same solute in different solvents. This work opens perspectives to choose simpler mass transfer models for process modelling, as well as pro-vides physical insight into which mass transfer mechanisms are important in OSN with ceramic membranes. @2022 Elsevier Ltd.
