Abstract

Research Subject: natural gas sweetening is one of the conventional and vital processes in gas industry, in which the CO2 and H2S separation is considered. A traditional methods such as absorption is employed for natural gas sweetening. High operational cost and also high energy consuming caused that these methods replaced by novel ones. Gas separation using membrane processes is one of the new methods that can be used in gas industry. Research Approach: In this study, the three phase Mixed matrix membranes comprising Pebax® 1657, PEG-200 and MIL-53(AL) nanoparticles were evaluated for CO2 Gas separation. The effect of various PEG-200 and MIL-53(AL) concentration within the Pebax polymeric matrix on the structure, gas permeability, and selectivity of the membranes was investigated. To study the cross-sectional morphology, crystallinity and thermal properties of the synthesized membranes, scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were utilized, respectively. Fourier transform infrared (FT-IR), was also carried out to identify the formation of the chemical bonds in the membrane. Main Results: SEM images demonstrated a uniform cross-section and admissible dispersion of nanoparticles. The results of the thermal analyses indicated an increase in crystallinity and Tg in presence of MIL-53 particles. Permeation of pure gases (i. e., CO2, CH4) through the prepared neat Pebax® 1657, the blended Pebax/PEG-200 and the Pebax/PEG-200/MIL-53(AL) Mixed matrix membrane was measured at the pressure of 10– 2 bar and temperature of 30 ° C. The results showed that at the pressure 10 bar, the CO2 gas permeation from 133. 36 Barrer in pure membrane increased to 311. 7 Barrer (%134) in a membrane containing %10wt MIL-53.
