博士 === 國立清華大學 === 化學工程學系 === 105 === 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.
