摘要

The rapid increase in atmospheric carbon dioxide (CO₂) from industrial and energy-related activities has intensified global climate change and environmental degradation. Conventional carbon capture systems such as amine-based absorption, adsorption, and cryogenic separation, while effective, face limitations including high energy consumption, corrosion, solvent degradation, and complex regeneration processes. To overcome these challenges, this study presents the development of a Water-Based Carbon Capturing (WBCC) system an innovative, sustainable, and low-energy solution for CO₂ mitigation. The WBCC system uses a mild alkaline aqueous solution, typically containing sodium carbonate or hydroxide, through which CO₂-rich air is passed. The CO₂ reacts with the solution to form stable carbonate solids that are non-toxic and can be reused in fertilizers and construction materials. The system employs a rotating bubble diffuser plate that generates fine, uniform microbubbles to ensure maximum gas–liquid interaction, enhancing capture efficiency while preventing clogging from precipitate formation. The design integrates AI-enabled sensors that automatically regulate air flow, pH, and temperature, optimizing absorption in real time. Preliminary experiments indicate a CO₂ capture efficiency of 80–85% under low-energy and ambient conditions. The WBCC system demonstrates high potential for scalable industrial deployment, offering a practical pathway for reducing carbon emissions and contributing to global decarbonization efforts. The novelty of the proposed WBCC system lies in the integration of a rotating microbubble diffuser, intelligent process control, ambient-condition operation, and carbonate recovery for circular carbon utilization. The study showcases a conceptual design and preliminary performance evaluation of the system while identifying pathways for future pilot-scale validation and industrial deployment.
