Abstract
AbstractCarbon dioxide separation from methane using membrane technology is getting attraction, and polymeric membranes are the most prominent polymer membrane materials. However, the existing polymeric membranes performance is inadequate due to trade‐off limitation open new windows to explore. Therefore, in this study, amine polymeric membrane (APM) has been fabricated by the addition of different concentration (5 wt.% and 15 wt.%) of diethanolamine (DEA). The developed amine polymeric membranes have been characterized in term of morphology and thermal analysis using field emission scanning electron microscope and thermogravimetric analyzer, respectively. The permeance and selectivity have been determined by using pure carbon dioxide (CO2) and methane (CH4). Also, the effect of amine concentration on permeance and selectivity has been studied. The results confirmed the symmetric and homogenous structure and thermal stability of membranes up to 490 °C. The maximum percent increase by the 15 wt.% addition of diethanolamine is 102.08 % at 10 bar pressure.
