EXPERIMENTAL AND THEORETICAL INVESTIGATION ON MATERIALS, PREPARATION, PERFORMANCE AND STABILITY OF IMMOBILIZED LIQUID MEMBRANES FOR GAS SEPARATION

Abstract

The work at hand deals with Immobilized Liquid Membranes (ILM) for gas separation. In immobilized liquid membranes, the pores of a support are filled with a liquid. Poly-meric supports and organic liquids are often used for preparation of supported liquid membrane. Immobilized liquid membranes can be used for ion-liquid separations, liquid-liquid separations and gas-gas separations. A review on immobilized liquid membrane for gas separation comprising literature of the last 15 year, has been performed in this work. The literature review is focusing on the kind of supports and liquids, which are used for the preparation of immobilized liquid membranes. The performance of these membranes has been given in terms of permeability, selectivity and stability. A new membrane module has been designed and fabricated for insitu preparation of flat sheet immobilized liquid membranes. Novel immobilized liquid membranes have been developed with two different supports for the separation of propylene and propane gases. The results are shown in terms of permeabilities and selectivities of both gases for the respective membranes.
