“…In addition, gas-liquid systems require attention to the choice of absorbent. At present, amine solvents are the most studied CO 2 absorbents [23][24][25][26][27]. Although the carbon capture rate of amine solvents is high, the amine desorption process has the problems of high cost, high energy consumption, and low economic efficiency [28,29].…”

A hybrid system combined with a non-contact membrane and bubbling absorption is proposed to capture CO 2 from flue gas. The non-contact way of membrane and liquid absorbent effectively avoids the reduction of gas diffusion flux through the membrane. High-porosity ceramic membranes in hybrid systems are used for gas-solid separation in fuel gas treatment. Due to the high content of H 2 O and cement dust in the flue gas of the cement plant, the membrane is hydrophobically modified by polytetrafluoroethylene (PTFE) to improve its anti-water, anti-fouling, and self-cleaning performances. The results show that the diffusion flux of CO 2 through the membrane is still higher than 7.0 × 10 −3 mol/m 2 s (20% CO 2 concentration) even under the influence of water and cement dust. In addition, slaked lime selected as the absorbent is cheap and the product after bubbling absorption is nano-scale light calcium carbonate. To sum up, the hybrid system combining non-contact membrane and bubbling absorption is expected to be used to capture carbon dioxide from the flue gas of the cement plant.

“…Presently, the technology widely used for CO 2 extraction in the natural gas industry is chemical absorption, which is accomplished by a reactor tower with an alcohol amine solution to CO 2 remove gas components. However, studies have found that this proven method has caused high economic costs and energy consumption in industry.…”

Covalent organic framework (COF) membrane materials are being increasingly utilized in gas separation processes due to their low-carbon, clean, and efficient properties. These materials are expected to have large-scale industrial applications in natural gas clean-up and separation processes. The separation effects of COFs materials vary for the CO2 membrane separation process, which has a significant impact on gas recovery. This paper aims to compare the mass transfer patterns of different COFs to separate CO2 and to expose the mechanism of separation. Employing a combination of Monte Carlo (GCMC) and molecular dynamics (MD) methods, this paper analyzes the mass transfer behaviors of CO2 separation from CH4/CO2. The study also examines the thermodynamic parameters, such as separation temperature, separation pressure, and gas components, to reveal the properties of CO2 separation from different COFs and the transport rules of gas molecules at the microscopic level. The findings suggest that pore size, CO2 concentration, and lower temperature environment contribute to the ability of CO2 adsorption. Additionally, COFs with oxygen-containing groups (NUS-2, COF-5, etc.) have better diffusion separation ability, and the AA stacking forms should be maintained during the process of completing the diffusion separation CO2. This paper could provide the essential basis for the design and adjustment of the structure of COFs and the enhancement of the gas membrane separation technology.

“…Conventional solvents such as monoethanolamine (MEA) and diethanolamine (DEA) have been used in membrane contactors due to their high reactivity toward CO 2 , low price and good biodegradability, 20,21 but they do not prevent wetting 22‐24 . Thus, recent research has focused on the use of other solvents such as amino acids (AAs), 25‐27 ionic liquids 28‐30 or ammonia 31‐33 in order to replace alkanolamines.…”

BackgroundCurrent technologies for carbon dioxide (CO2) capture are based on a variety of physical and chemical processes using absorption towers. Overcoming the high energy consumption of conventional absorption is essential to develop a process that makes sense in terms of CO2 captured versus CO2 emitted. In this work, we propose the use of a membrane contactor that allows an efficient gas–liquid contact and an aqueous alkaline solution with several amino acids (i.e. arginine, methionine, valine, serine, 6‐aminohexanoic acid) as the absorption liquid.ResultsResults show clear differences in absorption performance among the studied amino acids, with arginine as the best choice. Using arginine does not only lead to the highest mass transfer coefficient (ca 0.004 m3 m−2 min−1) in the membrane contactor but also a remarkable CO2 absorption capacity without the need for an alkaline component that enhances the reaction and the mass transfer.ConclusionThe use of membrane contactors with a green solvent is a promising step that needs further studies. As the results demonstrate, arginine has shown a great performance; thus, it has been chosen for further investigation. © 2023 Society of Chemical Industry.
