Removal of CO2 from natural gas by Zeolite Membranes; Modeling aspects

In this study a general model was developed using a combination of extended Longmuir and Maxwell-Stefan formulation to describe the separation of CO2 from natural gas by silicalite-1 membrane. The developed model is fully coupled model in which the thermodynamic and kinetic interactions between different diffusing components have been taken into account. The unique advantage of the present model is its capability in prediction of mixture separation performance in terms of permeability and selectivity using only pure component adsorption and permeation data. The results indicated that the different interactions have a major effect on the separation performance and should be properly considered in the transport model via the zeolite membrane
