제목 Kinetics of Carbon Dioxide in Aqueous Sodium Glycinate Solution
초록 In the present work, the reaction between CO2 and sodium glycinate has been studied by using wetted wall column apparatus at various temperature. These results would be applied in the basic absorption process related to design of acid gas treatment equipment for acid gas removal in our future work.
The physical solubility of N2O and CO2 aqueous sodium glycinate solutions of various concentrations at T = (303.15 to 323.15) K were recorded. It was found that while physical solubility increases with increase in sodium glycinate mass fraction, it decreases with decrease in temperature. The diffusivity of N2O and CO2 in aqueous sodium glycinate solution of various concentrations at different temperatures was also recorded. It was found that diffusivity decreases with increase in sodium glycinate mass fraction and decrease is more severe at higher temperature. Based on the pseudo-first order for the CO2 absorption, the overall pseudo first-order reaction rate constants were determined. The second-order rate constant of CO2 with sodium glycinate was found to be as k2 (m3 kmol-1 s-1) = 1.95×1013 exp[-7670/(T/K)].
