The facilitated transport of propylene through immobilized liquid membrane with $Ag^+$ as a carrier was investigated.
Propylene/methane was used as a model system to study the degree of separation between Olefin and Paraffin through this immobilized liquid membrane. Highly efficient liquid membranes were prepared by soaking the microporous Milipore filters in $AgNo_3$ solution.
Experiments were performed to find the influence of propylene partial pressure, ($Ag^+$) and membrane thickness on the propylene facilitation and the separation of methane/propylene. Also algebraic equations of equilibrium limit were tested to match the experimental data. It was found that under experimental conditions facilitation ratio and selectivity of propylene were decreased as propylene partial pressure increased. Also capacity of unit ($Ag^+$) was decreased as ($Ag^+$) was increased.
It could be concluded that Ag-propylene system is equilibrium limit because there was no significant changes in facilitution with the changes of membrane thickness.
Permeabilities on the order of 1.1 - 2.6 × $10^{-6}$cc-cm/㎠·sec·cmHg and selectivities on the order of 50-100 were obtained under experimental conditions, which could be regarded as a desirable results.
