Control of calcium carbonate polymorphism in the CO2 mineralization process |
| 초록 |
Chemical absorption using aqueous amine solution is considered to be the most applicable technology for CO2 capture. Even though the technology is already mature, it’s a major challenge that this technology estimate 70-100% electricity cost increment, mainly because of high energy consumption in the regeneration process. To help offset the electricity cost of conventional CCS technology, novel technologies propose to mineralize CO2 absorbed in amine solution instead of regeneration process. In this work, different polymorph crystals of calcium carbonate were prepared by CO2 mineralization process with different experimental condition such as feed rate of calcium ion source, mixing rate, and temperature. The effect of experimental parameter on the structure of CaCO3 in the mineralization process was investigated. |
