Abstract Liquid‐based CO 2 direct air capture (DAC) is a pivotal technology for mitigating climate change. Energy‐intensive desorption, high regeneration temperatures, and solvent degradation are key challenges. Here, low‐temperature catalytic membrane vacuum (C‐MVR) as promising approach sustainable energy‐efficient DAC developed evaluated. Noncatalytic experiments conducted using three commercial modules four green amino acid salts under varying conditions (e.g., temperatures flowrates). Based on transfer rates, ultra‐thin dense composite membranes aqueous potassium taurinate (TauK) the most MVR in applications. For C‐MVR trials, ion‐exchange resin improves desorption fluxes by up to 64.4% reduces thermal energy requirements 39.1%. TauK demonstrates highest flux lowest consumption. Parametric analysis of catalyst performance amount, concentrations also performed. To minimize any potential precipitation TauK, carbonate (K 3 ) added, showing minimal impact kinetics improvement. The findings this study highlight practical applicability boost rate reduce input.

Solvent regeneration is a pivotal component in CO2 capture technology, primarily due to its high energy consumption, which constitutes the most significant cost factor. In present study, application of gas–liquid vortex reactor (GLVR) as new process intensification (PI) technology for solvent introduced. An experimental study 30-weight percentage (wt %) monoethanolamine (MEA) aqueous solution loaded with performed. The important conditions are studied experimentally, including gas flow rate (15 25 N m3/h), liquid (20–40 kg/h), and loading MEA (0.28–0.49 mol CO2/mol MEA). this operational range, desorption efficiency peaks at 74%. As first assessment use, work adopts release per unit volume key performance indicator compare GLVR other PI technologies. Our findings indicate that significantly surpasses benchmark demonstrating potential more efficient alternative technology.
