ABSTRACT
This chapter expands the incorporation of J-factor into other two-phase models and investigates its impacts on the predictive performances of the models. It provides a good platform for future research works on developing an improved mixed matrix membrane (MMM) permeability model and its applications in gas separation using MMMs. These models were mostly derived for two-phase and three-phase scenarios. Lewis-Nielsen permeability model has its roots from an elastic modulus model proposed by Lewis and Nielsen and thermal conductivity model developed by Nielsen both for particular composite materials. The Chiew and Glandt model takes into account the variations of polymer-particle and particle-particle interactions on gas permeability. Similar to the Maxwell, Bruggeman, Bottcher, Higuchi, Lewis-Nielsen and Pal models which can be applied for liquid-liquid mixture and gas permeability, this model is also adopted for estimating gas permeability in MMMs. Accurate and simple permeability models are essential for evaluating the separation efficiency of gas sep.
