A probabilistic model for the motion of gas molecules through pores of microporous membranes is proposed. The interaction energy between the gas molecules and the surface of membrane pores is investigated using molecular modeling and results are used as input to the probabilistic model. The proposed model was used to evaluate the effect of surface coating on gas permeation of air and ammonia through single- and double-layer microporous membranes. Gas transmission experiments were conducted on uncoated polyethylene terephthalate (PET), nylon and PP/PE, coated PET, and double-layer PET microporous membranes at different pressure levels. Model results were compared with experimental data and a reasonable conclusion was drawn.
