“…The observed enhancement factors appeared to decrease with decreasing driving force. This phenomenon might be related to the phenomena reported by Littel et al (1991) for gas absorption into nonaqueous solutions in a stirred cell absorber. As yet the assumption of a thin toluene layer appears to explain most of the observed phenomena for gas absorption into toluene/water emulsions.…”

Abstract:The aim of this paper is to present a brief review of the determination methods of reaction kinetics in gas-liquid systems with a special emphasis on CO2 absorption in aqueous alkanolamine solutions. Both homogenous and heterogeneous experimental techniques are described with the corresponding theoretical background needed for the interpretation of the results. The case of CO2 reaction in aqueous solutions of methyldiethanolamine is discussed as an illustrative example. It was demonstrated that various measurement techniques and methods of analyzing the experimental data can result in different expressions for the kinetic rate constants.

“…Therefore, we concluded that the CO 2 absorption process was liquid-phase-controlled. To estimate the liquid-side mass transfer coefficient k L , a procedure earlier outlined by Littel et al [31] was used. For the case of physical absorption in a stirredcell reactor, a solute mass balance for both the gas and the liquid phase yields the following expression:…”

The polyethyleneamines ethylenediamine (EDA) and diethylenetriamine (DETA) can be considered as promising CO 2 -capturing solvents, producible from renewable resources. In the present work, kinetics of CO 2 reactions with EDA and DETA was investigated by using a stirred-cell reactor. The molarities of EDA and DETA in the aqueous solutions were varied from 0.1 to 0.4 and 0.1 to 0.5, correspondingly. The observed pseudo-first-order reaction rate constants were measured at 303, 308, and 313 K. The zwitterion and termolecular mechanisms were used to correlate the rate constants. DETA was found to have higher reactivity with CO 2 than EDA. Second-order rate constants for the reactions with EDA and DETA were equal to 15770 and 21480 m 3 /(kmol s) at 303 K. The activation energy values for EDA and DETA were found to be 57.7 and 30.2 kJ/mol, respectively.
