“…The presence of CO 2 in natural gas causes pipeline corrosion, increases the volume of gas transported through pipelines, and decreases the calorific value of the natural gas [2,[7][8][9]. Methods commonly used for CO 2 removal from CH 4 include absorption, adsorption, cryogenic distillation, and membrane technology [10]. All these methods are relatively complex and require high costs as compared to membrane technology [2,3,[10][11][12].…”

Removal of CO 2 from natural gas is necessary to purify the gas and to enhance its calorific value. Membrane technology is an efficient technique for CO 2 removal due to its ease of operation and low cost. Polymeric membranes exhibit excellent separation performance which is affected by plasticization and swelling in the membrane. Recent technological advancements and major problems in polymeric membranes are reported in this review. Separation performance of polymeric membranes is highlighted in terms of permeability and selectivity. Moreover, techniques to overcome the major problems in polymeric membranes are reviewed. Commonly, cross-linking and thermal treatment are used to minimize the effect of plasticization and swelling in the membrane. For future perspectives, there is a need to find more efficient methods to overcome these problems.

“…Moghadassi et al functionalized a CA membrane using multiwalled carbon nanotubes, providing an increase in perm-selectivity compared to pristine CA membranes. Moreover, the addition of organic additives, such as polyethylene glycol (PEG), improved the flexibility of the membrane, implying an increase in permeability and aging In this scenario, membrane technology has been selected as one of the efficient technologies to reduce CO 2 emissions in the atmosphere by separation/capture processes from the flue gas, such as natural gas and synthesis gas, achieving sustainable development goals with the creation and utilization of sustainable energy sources [9,10] The most important properties of membranes to perform this separation are: (1) high CO 2 permeability, (2) high CO 2 /CH 4 selectivity, (3) stability of the material, (4) good resistance to aging and plasticization, (5) sustainability and reproducibility of the manufacturing to levelize the fabrication cost upon up-scaling [11]. The most matured membranes for CO 2 separation are based on polymeric materials.…”

Biopolymer-Based Mixed Matrix Membranes (MMMs) for CO2/CH4 Separation: Experimental and Modeling Evaluation

Alternative materials are needed to tackle the sustainability of membrane fabrication in light of the circular economy, so that membrane technology keeps playing a role as sustainable technology in CO2 separation processes. In this work, chitosan (CS)-based mixed matrix thin layers have been coated onto commercial polyethersulfone (PES) supports. The CS matrix was loaded by non-toxic 1-Ethyl-3-methylimidazolium acetate ionic liquid (IL) and/or laminar nanoporous AM-4 and UZAR-S3 silicates prepared without costly organic surfactants to improve CO2 permselectivity and mechanical robustness. The CO2/CH4 separation behavior of these membranes was evaluated experimentally at different feed gas composition (CO2/CH4 feed mixture from 20:80 to 70:30%), covering different separation applications associated with this separation. A cross-flow membrane cell model built using Aspen Custom Modeler was used to validate the process performance and relate the membrane properties with the target objectives of CO2 and CH4 recovery and purity in the permeate and retentate streams, respectively. The purely organic IL-CS and mixed matrix AM-4:IL-CS composite membranes showed the most promising results in terms of CO2 and CH4 purity and recovery. This is correlated with their higher hydrophilicity and CO2 adsorption and lower swelling degree, i.e., mechanical robustness, than UZAR-S3 loaded composite membranes. The purity and recovery of the 10 wt.% AM-4:IL-CS/PES composite membrane were close or even surpassed those of the hydrophobic commercial membrane used as reference. This work provides scope for membranes fabricated from renewable or biodegradable polymers and non-toxic fillers that show at least comparable CO2/CH4 separation as existing membranes, as well as the simultaneous feedback on membrane development by the simultaneous correlation of the process requirements with the membrane properties to achieve those process targets.

“…A membrane is a thin semipermeable layer that separates two phases by selectively allowing the transport of one chosen component under a specific driving force 25, 26. The main characteristic of the membrane is to permit certain species to pass through it while blocking the rest of components, hence this way it controls the permeation of different molecules across the membrane 27.…”

A comprehensive overview of membrane technology used for natural gas purification and other gas separation applications including methods, materials, and results described in previous studies is presented. Different membrane categories are elaborated thoroughly followed by comparisons made between glassy and rubbery polymeric membranes. Various approaches to improve membrane separation performance, such as incorporation of inorganic fillers and blending technique, are discussed. Gas separation in different membranes, e.g., glassy/rubbery polymer blend membranes, mixed matrix membranes, and polymeric blend mixed matrix membranes, are considered. Adopted techniques by researchers to solve existing issues in membrane fabrication and performance are explained in detail.
