Title: Selective CO[sub 2] separation from CO[sub 2]-N[sub 2] mixtures by immobilized carbonate-glycerol membranes

Abstract

Acid gases present in numerous industrial waste gas streams have caused increasing global environmental concerns. To alleviate the pollution problems, acid gases in such streams need to be removed. The increased demand for acid gas treating and the cost of purification by conventional processes suggest a need for energy-efficient and selective gas-treating technology. Recent application of membrane separation of CO[sub 2] has been attracting attention due to its inherent simplicity, ease of control, compact modular nature, and great potential for lower cost and energy efficiency compared to traditional separation methods. These attractive features have stimulated significant research in gas separation using polymeric as well as liquid membranes. Separation of carbon dioxide from a humid mixture of CO[sub 2]-N[sub 2] through membranes containing immobilized solutions of Na[sub 2]CO[sub 3]-glycerol in porous and hydrophilic poly(vinylidene fluoride) (PVDF) substrate was experimentally studied. The effects of Na[sub 2]CO[sub 3] concentration, CO[sub 2] partial pressure, and feed stream relative humidity (RH) were investigated.
