In this chapter, we present and explain the most powerful approaches currently available for the modelling of vapour permeation in membranes, focusing the attention on polymeric and mixed matrix membranes and on the solution-diffusion transport mechanism. After a brief general introduction on permeation modelling and on the peculiarities of vapour permeation, the attention will be focused on the solution-diffusion approach. In such a framework, one can use a separate model for the solubility and diffusivity contributions to the permeability. In particular, for the sake of conciseness, we will focus on the equation of state models, for the solubility, and on the free volume theory, for the modelling of diffusivity
