An Experimental and Modeling Investigation on Facilitated Transport Separation of Propylene-Propane Mixture

Immobilized liquid membrane, as one type of facilitated transport membranes, was used for the separation of propylene-propane mixtures. The effect of trans-membrane pressure and carrier concentration on membrane separation performance were evaluated in terms of propylene and propane permeation fluxes. Experimental results showed that for a 70:30 (vol.%) propylene-propane mixture, at trans-membrane pressure 120kPa and carrier concentration 20wt. %, a propylene permeation flux of 1.46*10-4 mol/m2.s was obtained. Mathematical results are in well agreement with experimental results. The average deviation between experimental and modeling results was found to be 5.3% for propylene permeation flux and 0.03% for propane permeation flux.
