Fabrication, Characterization and Performance Study of N-methyl-diethanolamine (MDEA)-Polyethersulfone (PES) Amine Polymeric Membrane for CO2/CH4 Separation

R. Nasir, H. Mukhtar and Z. Man    

Abstract: The polymeric membrane is a well-known membrane due to ease of processing and mechanical stability. These membranes extensively used for the separation of carbon dioxide from methane but the applications of these membranes are limited in order to achieve high permeability and selectivity. In this study the amine polymeric membrane has been fabricated by the addition of N-methyl-diethanolamine in polyethersulfone solution, the N- methyl-2 pyrrolidone used as solvent. The characterization of fabricated membrane has been carried out in order to investigate the morphology, thermal properties and identification of functional group by using field emission scanning electron microscope, thermo gravimetric analyzer and fourier transform infrared spectroscopy. The permeability and selectivity study were also carried out by using pure carbon dioxide and methane. The permeability and selectivity has been increased as compared to pure polyethersulfone membrane.
