This work presents experimental data and a model for the initial kinetics of CO 2 into 3-(methylamino)propylamine (MAPA) solutions. MAPA has been tested as an activator for tertiary amines with encouraging results. The measurements were performed in a string of discs contactor and, since no initial kinetics data is available in literature, additional measurements were carried out and in a wetted wall column. The obtained overall mass transfer coefficients from both apparatuses are in reasonable agreement. To obtain values for the observed kinetic constant, obs k , the experimental results were interpreted using a two-film mass-transfer model and invoking the pseudo first order assumption. Needed experimental values for density, viscosity and Henry's law coefficient for CO 2 were measured and are given. The results indicate that MAPA is almost twice as fast as PZ, 8 times faster than AEEA, and 15 times faster than MEA, when comparing unloaded 1M solutions at 25ºC. The observed kinetic constant was modelled using the direct mechanism. The final expression for obs k can be applied for any concentration and temperature within the experimental data range, and, together with the presented physical data, comprises a complete model for calculating absorption fluxes.

“…Thus, for the development of new cost effective CO 2 capture processes, many research groups have focused on the reduction of regeneration energy by suggesting mixture solvent systems such as mixed amine systems (Aronu et al, 2010;Austgen et al, 1991;Barzagli et al, 2011;Bishnoi and Rochelle, 2002b;Bougie and Iliuta, 2010;Brúder et al, 2012;Dubois and Thomas, 2012;Seo and Hong, 1996).…”

Abstract2-(Diethylamino)ethanol (DEEA) and 3-(Methylamino) propylamine (MAPA) in combination may represent a promising absorbent system for CO 2 capture due to high CO 2 loading capacity, high equilibrium temperature sensitivity, low energy requirement for regeneration and relatively high reaction rate.Three different systems: DEEA-CO 2 -H 2 O; MAPA-CO 2 -H 2 O and DEEA-MAPA-CO 2 -H 2 O were studied quantitatively by NMR spectroscopy and the data are reported in the present work. The main products quantified for these systems are: carbonate-bicarbonate for the DEEA-CO 2 -H 2 O system; primary, secondary carbamate, dicarbamate for the MAPA-CO 2 -H 2 O system, and primary/ secondary carbamate, dicarbamate, carbonate/bicarbonate in blended DEEA-MAPA-CO 2 -H 2 O. The speciation data of the three systems were measured and reported in the present work. The blended system of 5M DEEA-2M MAPA can form two liquid phases after being loaded with CO 2 and both phases were analyzed quantitatively by NMR spectroscopy. The experimental data shows that the lower phase is rich in CO 2 and MAPA while the upper phase was lean in CO 2 and rich in DEEA. The ratio DEEA-MAPA in the lower phase increases with increasing partial pressure whereas for the upper phase the opposite is true.

“…11.5 Results of Multi Scale Design 299 MAPA is also an interesting option because it combines a primary and a secondary amine group, which enables increased reaction rates. In this context, it has been combined with N,N-dimethylaminoethanol (DMMEA) (Bruder et al, 2012) and N,N-diethyl-2-aminoethanol (DEEA) (Hartono et al, 2013). MAPA-DEEA mixtures form two liquid phases upon CO 2 loading, one rich and the other lean in CO 2 .…”
