Effect of Operating temperature on carbon dioxide and nitrogen permeabilities in nanocomposite membrane to prevent the greenhouse gases emission

Abstract The capture and storage of carbon dioxide has been identified as one potential solution to greenhouse gas driven climate change. A developing technology is membrane gas separation, which is more compact, energy efficient and possibly more economical than mature technologies, such as solvent absorption. Poly vinyl chloride/multi wall carbon nano tubes (PVC/MWCNTs) nanocomposite membranes (NCMs) were prepared for gas separation. functionalized MWCNTs (OH-MWCNTs) was utilized in membranes preparation. Gas permeation and transport characteristics of single gases for CO2 and N2 were investigated and analyzed using constant pressure method. The as-prepared PVC/MWCNTs was characterized by scanning electron microscopy(SEM). Trans-membrane temperature were varied from 298.15-308.15 K. The temperature dependency of permeability for both CO2 and N2 was increased with an increase in temperature.
