Kinetic Separations of CO2/C2H6 Mixtures

The separation of CO2/C2H6 is relevant in the context of natural gas processing. Current technologies for CO2/C2H6 separations use extractive distillation because of CO2/C2H6 azeotrope formation. Another alternative is to combine distillation technology with membrane separations; for this purpose cross-linked polyethylene oxide (XLPEO) membranes have demonstrated to have good separation potential. I suggest the possibility of diffusion-selective purification of ethane by selective removal of CO2 present as impurities in mixtures with ethane using DDR zeolite. I also examine the influence of three separate factors that influence kinetic separations: (a) diffusional time constant, (b) gas-crystal contact time, and (c) Ratio of Maxwell-Stefan diffusivities.
