Abstract
To describe gas transfer through a bilayer membrane with a thin selective layer on the surface of a highly permeable gutter layer, it was first proposed to take into account the interlayer resistance arising at the boundary of this membrane layers and a model of gas transfer through a bilayer membrane was developed. An analytical expressions for permeability and selectivity of such a membrane taking into account this resistance is obtained. It is shown that the interlayer resistance can noticeably affect the transport characteristics of the membrane. It is found that even in the case of small diffusion resistance to gas permeation of the gutter layer, its sorption and kinetic parameters influence the permeability and selectivity of the membrane as a whole.
