コジェネレーション向けCCSを対象とした化学吸収法での物質移動係数に及ぼすバブリングの影響

抄録

CO₂ overall mass transfer coefficient in a reactor plays a key role in CO₂ capture rate of CCS. This work has investigated the overall mass transfer characteristics of the packed bubble absorber column in the amin-based CCS for exhaust gas from the cogeneration system. The results have indicated that the overall mass transfer coefficient is more enhanced with increasing the bubble layer formed in the lower part of the absorber than the liquid film formed in the upper part. It has been also revealed that the bubble layer height was the most sensitive factor in design variables for increasing of not only the overall mass transfer coefficient but also the CO₂ capture rate.
