Solution-Diffusion Model for Single Gas Transport

Transient gap between chains in matrix allows penetrant to diffuse. 

The transport through CMSMs is often studied by using the solution (sorption)-diSusion model. Because of simplicity of the model, a brief description is given below for the transport involved in a single gas system. 

When the solubility of gas in the membrane follows the Henry s law relationship 

Combining Eqs. (2.1) and (2.2) arrd irrlegrating from the feed side to the permeate side of the membrane, we obtain 

Permeability, solubility and diffusivity can all be represented by Arrherrirrs type
