“…In addition, Mohammaddoost et al 32 claimed that the CO 2 desorption rate of the rich water-based nanofluids exceeded 97%. Mohammed et al 14 simulated the CO 2 desorption process in SiO 2 −MEA nanofluids for the first time in the HFMC. It was noted that the gas-phase flow rate had a negligible effect on the desorption effect compared to the liquid-phase flow rate.…”

The emission of greenhouse gases, especially CO2, has become a major cause of environmental degradation, and carbon capture, utilization, and storage (CCUS) is a proposed solution to mitigate its impact. Nanofluids, a relatively new method for CO2 absorption, have gained attention in recent years. This review focuses on conventional methods for preparing nanofluids along with techniques to improve their stability and enhance the CO2 absorption and desorption mechanisms. Additionally, the influences of factors, i.e., nanoparticle and base solution types as well as nanoparticle concentration, on the CO2 absorption process are summarized. Furthermore, models that can predict the absorption of CO2 accurately are outlined. It is found that the types of both base liquids and nanoparticles have an important impact on the absorption by nanofluids. In-depth studies on the predictive capabilities of artificial intelligence (AI) models hold immense potential in this regard. This review also puts forth effective strategies to address prevailing challenges. This will provide a solid theoretical basis for this field and underscore the promising potential of nanofluids as CO2 solvents. There are still many unexplored aspects to be considered, such as the economic viability and energy consumption of this technology.

“…Using a solvent with higher surface tension could lower the possibility of membrane wetting. 18,19 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][23][24] Thus, recent research has focused on the use of other solvents such as amino acids (AAs), [25][26][27] ionic liquids [28][29][30] or ammonia [31][32][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.

Modeling and Simulation of the Impact of Feed Gas Perturbation on CO2 Removal in a Polymeric Hollow Fiber Membrane

A membrane contactor is a device that attains the transfer of gas/liquid or liquid/liquid mass without dispersion of one phase within another. Membrane contactor modules generally provide 30 times more surface area than can be achieved in traditional gas absorption towers and 500 times what can be obtained in liquid/liquid extraction columns. By contrast, membrane contactor design has limitations, as the presence of the membrane adds additional resistance to mass transfer compared with conventional solvent absorption systems. Increasing mass transfer in the gas and solvent phase boundary layers is necessary to reduce additional resistance. This study aims to increase the mass transfer in the gas phase layer without interfering with membrane structure by oscillating the velocity of the feed gas. Therefore, an unsteady state mathematical model was improved to consider feed gas oscillation. The model equation was solved using Comsol Multiphysics version 6.0. The simulation results reveal that the maximum CO2 removal rate was about 30% without oscillation, and at an oscillation frequency of 0.05 Hz, the CO2 percent removal was almost doubled.
