For efficient gas separation the membrane technology is rapidly growing day by day and it is more economical and effectual than past technologies. The main objective of this study is to synthesis polymer blend membranes (PBM) using glassy polysulfone (PSU) and rubbery polyvinyl acetate (PVAc) with the addition of methyl diethanol amine for removal of CO2 from CH4. The PBM were developed by varying the composition of PVAc ranging from 5 to 20 wt% with 80 to 100 wt% PSU in DMAc solvent. The amine composition was added to the blend and kept at 10 wt%. The present of MDEA in the PBM had increased the CO2 permeance as compare with the based polymer membranes. However as the operating pressure increased from 2 to 10 bar, the PBM (PSU95%/PVAc5%) with MDEA was found to increase significantly the permeance of CO2, hence increasing the separation factor from 9.980.02 to 30.190.49. EPBM was found a very promising to be used for CO2/CH4 separation.

Development of polymer blend membranes is gaining much attention especially for gas separation processes. This paper is primarily focused on synthesizing polymer blend membranes incorporated with titanium dioxide (TiO2) nanoparticles as inorganic filler to enhance its performances. Polyethersulfone (PES) and polyvinyl acetate (PVAc) were blended at ratio of 90/10, together with 5 wt.% of TiO2 in dimethylformamide (DMF). The morphological structure of the membrane was analysed via FESEM. It shows that a rigid/non-porous membrane with slight nanoparticles agglomeration was formed. As interpreted from TGA, incorporating TiO2 nanoparticles into the polymer blend reduces the degradation temperature, increases wt.% of leftover residual thus proves an enhancement in thermal stability of the membrane. Moreover, the presence of TiO2 nanoparticles in the developed membrane possesses some effect on the spectral analysis as observed via FTIR spectroscopy. The permeability of CO2 gas is improved with addition of TiO2 nanoparticles within the blend membrane and better selectivity of CO2/CH4 is observed.

In this research work, polyethersulfone (PES) and polyethersulfone/polyvinyl acetate (PES/PVAc) blend were incorporated with 10 wt.% of TiO2 nanoparticles to form mixed matrix membranes (MMM). FESEM and TGA were utilized respectively to scrutinize the morphology and thermal stability of the developed membranes. Permeation tests of ideal CO2 and CH4 gases were also conducted to assess the separation performance of resultant membranes. The PES/PVAc/TiO2 polymer blend MMM was found to be the most thermally resistant and has the highest CO2 permeability and CO2/CH4 selectivity as compared to the other membranes.
