摘要:	The contributions of this dissertation are listed as following: • Developed a model of the carbon dioxide absorption by monoethanolamine and dilute ammonia solutions in a rotating packed bed based on two-film theory. • Found out that temperature bulge can be found in the rotating packed bed when a large amount of carbon dioxide was removed. • Found out that use of a modified expression for the apparent kinetic constant in the enhancement factor is necessary to predict experiment results using high amine concentrations. • Compared to the traditional packed bed and rotating packed bed by models for different throughput rates, ranging from bench scale to industrial scale. • Found out that the apparent intensification effect of the rotating packed bed is more significant for ammonia than for monoethanolamine solution because of the different operating of CO2 loading. • Found out that the Height of a Transfer Unit is inappropriate to be an indicator for intensification effect of volume. 此論文貢獻如下: • 建立醇胺與稀釋氨水溶液基於雙模理論之超重力轉床模型 • 發現溫度凸波存在於旋轉床之中當大量二氧化碳被移除 • 發現使用修正的表面反應常數在二氧化碳增強因子之中是必要的以增強在高濃度醇胺吸收劑之預測能力 • 使用傳統吸收塔與超重力旋轉床模型進行實驗及到工業級吞吐量的差異比較 • 發現使用氨水溶液，超重力旋轉床有較佳的表現，主要是因為CO2 loading 操作差異造成 • 發現單位質傳高度(Height of a Transfer Unit)不適合作為比較差異的指標 • 體積質傳速率(Volumetric mass transfer rate )為較適合的指標
