Alkanolamines are the most popular absorbents used to remove CO 2 from process gas streams. Therefore, the CO 2 reaction with alkanolamines is of considerable importance. The aim of this article is to provide an overview on the kinetics of the reaction of CO 2 with aqueous solutions of alkanolamines. The various reaction mechanisms that are used to interpret experimental kinetic data -zwitterion, termolecular and base-catalyzed hydration -are discussed in detail. Recently published data on reaction kinetics of individual amine systems and their mixtures are considered. In addition, the kinetic behavior of several novel aminebased solvents that have been proposed in the literature is analyzed. Generally, the reaction of CO 2 with primary, secondary and sterically hindered amines is governed by the zwitterion mechanism, whereas the reaction with tertiary amines is described by the base-catalyzed hydration of CO 2 .

The process of pure carbon dioxide absorption is analyzed in aqueous solutions of N-methyldiethanolamine (MDEA). The experiments were made in a stirred tank reactor with a plane and known interface area. The variables considered were the MDEA concentration within the range 0.1-3.0 M and the temperature in the interval 288-313 K. From the results, we deduce that the process takes place under isothermal conditions and moderately fast regime, with second-order kinetics. We determined a reaction order of one with respect to the amine, and an expression for the kinetic constant valid throughout the entire range of temperatures and concentrations assayed ln k = 22.4 − 6243.5/T .

“…Mitigation technology such as chemical absorption is the widely used solution to reduce greenhouse gas emissions from thermal power plants in a short period [15][16][17][18][19][20]. In search of a new absorbent, we are studying sodium glycinate (SG) solution as an absorbent for CO 2 .…”

In this paper, density, viscosity, surface tension and vapor pressure of aqueous sodium glycinate solutions of different mass fractions (0.1-0.5) at different temperatures (20-100 o C) were simulated using Pro/II (version 6.01), a commercial process simulator, and compared with corresponding experimentally measured data. It was found that simulated data of physicochemical properties compared well with corresponding experimental data. We have also predicted concentration of CO 2 with each ideal stage in an absorber/stripper tower.
