Carbon dioxide capture with tertiary amines. Absorption rate and reaction mechanism

Present work analyzes the overall carbon dioxide chemical absorption process using tertiary amines in aqueous solution, taking into account absorption rate experimental data and 13C and 1H nuclear magnetic resonance. These studies try to detect the causes because different behaviors are obtained for absorption curves at different carbon dioxide loadings. The combined use of these techniques allows to evaluate the weight of different variables (chemical kinetics, mechanism, hydrodynamics, etc) upon the absorption overall process.
