“…For pure PEI membrane, a rise in feed pressure resulted a decrease in CH 4 permeability and an opposite trend of CH 4 permeability was observed in pure PVAc membrane. These trends were in line with the literature . For PEI/PVAc blend membranes, similar increasing trend was observed in Fig.…”

“…Its chemical resistance is good, but it may be attacked by halogenated hydrocarbons, dipolar aprotic solvents, cresol, and concentrated acids and bases . The aromatic imide units provide stiffness and heat resistance, while the swivel groups such as ‐O and ‐C(CH 3 ) 2 form flexible macromolecular chains that allow good processability . It has typically low CO 2 permeability and very high CO 2 /CH 4 selectivity .…”

This article presents fabrication, characterization, and performance evaluation of polyetherimide (PEI)/polyvinyl acetate (PVAc) blend membranes. Polymer blend membranes with various blend ratios of PEI/PVAc were prepared by solution casting and evaporation technique. Morphology and miscibility of polymer blend membranes were characterized by field emission scanning electron microscope (FESEM) and differential scanning calorimetry (DSC), respectively. The interaction between blend polymers was analyzed by FTIR analysis. Gas separation performance was evaluated in terms of permeability and selectivity. FESEM results revealed that pure polymer and blend membranes were homogeneous and dense in structure. A single glass transition temperature of polymer blend membranes was found in DSC analysis which indicated the miscibility of PEI/PVAc blend. FTIR analysis confirmed the presence of molecular interaction between blend polymers. The permeation results showed that the presence of PVAc (3 wt%) in blend membranes has improved CO2 permeability up to 95% compared to pure PEI membrane. In addition, CO2/CH4 selectivity was found to be 40% higher than pure PEI membrane. This study shows that blending a small fraction of PVAc can improve the gas separation performance of PEI/PVAc blend membranes. POLYM. ENG.

“…There were three types of membrane contactors observed across the 525 studies: flat sheet (FS) (n = 79, 15%) [90,93,98,117,127,137,180,181,187,193,199,212,218,222,230,[238][239][240][243][244][245]248,249,256,267,268,278,282,284,287,289,302,305,[312][313][314][315]317,321,323,324,326,329,333,336,338,[343][344][345]347,352,356,…”

With fossil fuel being the major source of energy, CO2 emission levels need to be reduced to a minimal amount namely from anthropogenic sources. Energy consumption is expected to rise by 48% in the next 30 years, and global warming is becoming an alarming issue which needs to be addressed on a thorough technical basis. Nonetheless, exploring CO2 capture using membrane contactor technology has shown great potential to be applied and utilised by industry to deal with post- and pre-combustion of CO2. A systematic review of the literature has been conducted to analyse and assess CO2 removal using membrane contactors for capturing techniques in industrial processes. The review began with a total of 2650 papers, which were obtained from three major databases, and then were excluded down to a final number of 525 papers following a defined set of criteria. The results showed that the use of hollow fibre membranes have demonstrated popularity, as well as the use of amine solvents for CO2 removal. This current systematic review in CO2 removal and capture is an important milestone in the synthesis of up to date research with the potential to serve as a benchmark databank for further research in similar areas of work. This study provides the first systematic enquiry in the evidence to research further sustainable methods to capture and separate CO2.

“…These types of polymeric membranes contain ether groups which strongly interacts with CO 2 due to dipole-quadrupole interactions. Thus, those materials exhibit high selectivity towards CO 2 over nonpolar gases (such as CH 4 ) which cause high permeability and permselectivity of CO 2 through the PEBAX membranes [15][16][17][18][19][20][21][22][23].…”
