| 제목 | Comparative Study on Physicochemical Properties of Novel CO2 Absorbents |
| 초록 | Wet amine scrubbing using alkanolamine has been thought to be the most feasible method for the capture of CO2 from coal-fired power plant flue gases. Korea Electric Power Research Institute (KEPRI) has developed highly efficient CO2 absorbent solution named KoSol. It was proven that the recently formulated solution, KoSol-3, has superior performance in solvent regeneration energy, metal corrosivity, and thermochemical degradation than does 30 mass % monoethanolamine (MEA). The 2 ton CO2/day (0.1 MW)-scale pilot plant has been installed at Boryeong Power Plant and the field tests are ongoing using KoSol-3 as CO2 absorbent. In the present study, the characterization experiments were conducted on the candidates for the novel CO2 absorbents. Physical properties, such as density, viscosity, gas diffusivity, surface tension, heat capacity, and gas solubility, were measured. Overall reaction kinetic constant (kov), under the pseudo-first order reaction regime, was measured using stirred-cell reactor. From the measured data, the performances of the candidates were comparatively discussed. The data will be utilized for the design and optimization of the CO2 capture pilot plant. |
