Fundamental science of gas and vapour separation in polymeric membranes

Y. Yampolskii,     A.V. Topchiev Institute of Petrochemical Synthesis (TIPS), Russian Academy of Sciences Russia


This chapter discusses the principles of gas and vapour permeation and separation in non-porous polymeric membranes. The dependence of permeability, diffusion and solubility coefficients on the parameters of gaseous penetrants and properties of polymers are considered. Special sections deal with the effects of pressure and temperature on the transport parameters. A brief survey is given on membrane gas separation materials and the problems of gas separation that can be solved using membranes.
