本研究主要為探討CO2與混合醇胺DEA/AMP水溶液的反應動力學,其濃度範圍為DEA (0.1-0.4 kmol·m-3) / AMP (1.0 kmol·m-3)及DEA (0.1-0.4 kmol·m-3) / AMP (1.5 kmol·m-3),溫度是30、35及40C。對於CO2,本研究以pseudo-first-order的模式來描述反應動力,而對於DEA、AMP則用兩性離子機構來描述。同時也量測N2O在混合醇胺DEA/AMP水溶液中之亨利常數及擴散係數。由實驗結果可發現,本研究的實驗符合先前的假設,且兩性離子機構可以用來解釋DEA、AMP與CO2的反應。
另外,本研究也測量N2O在DIPA水溶液中的亨利常數及擴散係數,且將本研究所得的實驗值加上目前文獻上已發表的數據,整理出N2O在DIPA水溶液中亨利常數及擴散係數對於溫度及濃度的關係式。
The kinetics of the reaction between CO2 and diethanolamine (DEA) and 2-amino-2-methyl-1-propanol (AMP) aqueous solutions. The operation is at 30-40C. The concentrations are DEA (0.1-0.4 kmol·m-3) / AMP (1.0 kmol·m-3) and DEA (0.1-0.4 kmol·m-3) / AMP (1.5 kmol·m-3). The pseudo-first-order model and the zwitterion mechanism were used to describe the reaction of CO2 with DEA and AMP, respectively. The solubility and diffusivity of N2O in DEA/AMP aqueous solutions were also measured.
The solubility and the diffusivity of N2O in diisopropanolamine (DIPA) aqueous solutions were also studied.
The parameters of the calculations were determined from the literature values and the values obtained in this study.
