Abstract

Carbon capture and utilization (CCU) technology is receiving notable attention because carbon capture and storage (CCS) technology has some limitations. Using solid waste or natural minerals, CO2 capture can be achieved through the wet absorption-based CCU technology. This research proposes a novel process through which simultaneous and continuous carbon dioxide absorption, calcium component extraction, and production of calcium carbonate salt can be achieved. Also, recycling of the absorbent can be performed without requiring a thermal desorption step. The possibility of absorbent recovery was investigated, and the crystal structure of the produced calcium carbonate salt was proven to be vaterite. Based on the process, 0.566 tons of carbon dioxide was reduced per ton of CaO. The precipitated salt produced by carbonation reaction was determined to be vaterite by X-ray diffraction analysis and scanning electron microscopy images. To summarize, a continuous process using NH4NO3 is thought to have potential for application in industry. (Figure Presented).
