文摘
- •
Permeation across polymer membranes is influenced by diffusion and thermodynamics.
- •
Mixture diffusion is modelled with the Maxwell-Stefan formulation.
- •
Phase equilibrium thermodynamics is described by the Flory-Huggins model.
- •
Using matrix algebra explicit analytic expression are derived for the permeation fluxes.
- •
The model is verified by comparison with published experimental data.
