TL;DR: In this paper, a comprehensive model is developed for the absorption of carbon dioxide into aqueous mixtures of primary or secondary alkanolamines with tertiary alkanolamines, which incorporates an extensive set of important reversible reactions and takes into account the coupling between chemical equilibrium, mass transfer and chemical kinetics.

TL;DR: In this paper, the diffusion coefflclent and freegas solubllity of carbon dloxlde In aqueous methyldlethanol ammonne (MDEA) were also measured.

TL;DR: In this paper, a wetted-sphere absorption apparatus was used to measure the liquid-phase diffusion coefficients for hydrogen sulfide, carbon dioxide, and nitrous oxide over the temperature range 293-368 K. The experimental results obtained in this work are compared with values in the literature and with predictions from the Wilke-Chang equation.

TL;DR: In this paper, the partial pressure of carbon dioxide above a 50 mass % aqueous solution of methyldiethanolamine was measured as a function of the amount of CO 2 absorbed in the solution.

TL;DR: In this article, a wetted-sphere absorber was used to acquire kinetic data for the aqueous phase reaction between CO2 and N-methyldiethanolamine (MDEA), and three different mathematical models were developed and used to estimate the forward rate coefficient of the MDEA-catalyzed hydrolysis of CO2 reaction.
