“…Membrane wetting can occur for various reasons, including non-optimal material properties such as inadequate hydrophobicity, wrong pore size, low chemical resistance, and operational issues such as liquid evaporation and condensation 21 . As a result, wetting of membrane pores is a significant technical challenge for membrane contactors, as it can significantly increase mass transfer resistance 22 , 23 . While some efforts have been made to improve material hydrophobicity and increase permeability by using asymmetric membrane structures to reduce pore wetting, it is still an ongoing issue.…”

The release of excessive carbon dioxide (CO2) into the atmosphere poses potential threats to the well-being of various species on Earth as it contributes to global working. Therefore, it is necessary to implement appropriate actions to moderate CO2 emissions. A hollow fiber membrane contactor is an emerging technology that combines the advantages of separation processes and chemical absorptions. This study investigates the efficacy of wet and falling film membrane contactors (FFMC) in enhancing CO2 absorption in a monoethanolamine (MEA) aqueous solution. By analyzing factors such as membrane surface area, gas flow rate, liquid inlet flow rates, gas–liquid contact time, and solvent loading, we examine the CO2 absorption process in both contactors. Our results reveal a clear advantage of FFMC, achieving an impressive 85% CO2 removal efficiency compared to 60% with wet membranes. We employ COMSOL Multiphysics 6.1 simulation software and finite element analysis to validate our findings, demonstrating a close agreement between predicted and experimental values, with an average relative error of approximately 4.3%. These findings highlight the significant promise of FFMC for applications in CO2 capture.

“…The application of membrane absorption for CO 2 capture has encountered challenges related to membrane wetting (Park et al, 2017). To address this issue, Fu et al (2023b) undertook hydrophobic modification of Al 2 O 3 ceramic membranes by grafting 1H,1H,2H,2H-perfluorodecyltriethoxysilane. The modification led to a substantial enhancement in the wettability of the ceramic membranes.…”

Carbon capture, utilization and storage (CCUS) technologies play an essential role in achieving Net Zero Emissions targets. Considering the lack of timely reviews on the recent advancements in promising CCUS technologies, it is crucial to provide a prompt review of the CCUS advances to understand the current research gaps pertained to its industrial application. To that end, this review first summarized the developmental history of CCUS technologies and the current large-scale demonstrations. Then, based on a visually bibliometric analysis, the carbon capture remains a hotspot in the CCUS development. Noting that the materials applied in the carbon capture process determines its performance. As a result, the state-of-the-art carbon capture materials and emerging capture technologies were comprehensively summarized and discussed. Gaps between state-of-art carbon capture process and its ideal counterpart are analyzed, and insights into the research needs such as material design, process optimization, environmental impact, and technical and economic assessments are provided.
