To develop an energy-efficient and available carbon dioxide (CO₂) capture technique with amine-based solvents and membrane contactors (MCs), an innovative technological route was proposed to remove CO₂ from industrial flue gas by coupling MCs with catalyst-aided solvent regeneration (MC-CR). A laboratory-scale experimental setup with ceramic membrane module was then designed and built to accurately estimate the performance of the MC-CR route, using aqueous monoethanolamine (MEA) and powder metatitanic acid [TiO(OH)₂] as the solvent and catalyst, respectively. The results indicated that the nanofluid effect of the catalyst reduced the mass transfer resistance and promoted a concentration change in the liquid film, resulting in a high CO₂ absorption rate.The surface acidic sites of TiO(OH)₂ boosted the process of proton transfer in the solvent, thus facilitating the decomposition of carbamate. The CO₂ capture efficiency increased by 9.48% and the energy consumption of solvent regeneration considerably decreased by 40.8% at dosage of 2 wt% TiO(OH)₂. In addition, matched pressure regulation for gas–liquid flow in the MCs effectively avoided membrane fouling and wetting after 180 min continuous operation. Industrial-scale simulation indicated that the MC-CR route achieved a low capture cost at $46.7/t CO₂, a decrease of 28% compared with the cost of the traditional route. This study established the groundwork for developing MC technology as an effective approach for low-cost industrial CO₂ capture.
