Transmembrane gas transfer: Mathematics of diffusion and experimental practice
Abstract(#br)Transport parameters of gases and light hydrocarbons in polymeric membrane materials including their temperature and pressure dependencies are very important to know for estimation of perspective applications and optimal operating conditions of membranes and membrane modules in gas separation processes. Today, transport parameters of gases for more than 2000 polymers and copolymers have been accumulated systematically. Unfortunately, in most of cases only gas permeability coefficients under isothermal conditions have been measured.
