“…Our previous work [12] shows that, among the derivatives of PZ, 1MPZ is an outstanding solvent in terms of cyclic capacity and rough energy requirement. Therefore, this work aims at developing a rigorous thermodynamic model for the 1MPZ/CO 2 /H 2 O system to give an accurate calculation of the energy consumption in the capture process.…”

This work studies the potential of using the tertiary amines 3-dimethylamino-1-propanol (3DMA1P), 3-diethylamino-1-propanol (3DEA1P) and 1-(2hydroxyethyl)pyrrolidine (1-(2HE)PRLD) as an alternative to 2-(diethylamino)ethanol (DEEA) in the blend with 3-(methylamino)propylamine (MAPA). Vapour pressure of the three tertiary amines and vapour-liquid equilibrium (VLE) of the binary mixtures 3DMA1P/H2O, 3DEA1P/H2O and 1-(2HE)PRLD/H2O at T = (353, 363 and 373) K were measured in a modified Swietoslawski ebulliometer. The vapour pressure of the pure amines was fitted to the Antoine equation , and the P-T-x-y data were fitted to NRTL equations. VLE of the CO2 loaded blended amines were measured in the temperature range of T = 313 to 393 K, and speciation data of equilibrated samples at different CO2 loadings were obtained by NMR spectroscopy. The study showed that the tertiary amines 3DMA1P, 3DEA1P and 1-(2HE)PRLD in the binary amine/ H2O system were less volatile than DEEA in aqueous solution. The CO2 loaded blended amines showed comparable VLE behaviour, as well as speciation, and obtained a cyclic capacity higher than that of 30 wt% MEA but similar to most of the blended amines studied in the literature. The overall results indicated that the tertiary amines studied in this work can be used as an alternative to DEEA.

In energy industry as petrochemicals and electricity generation, absorption technology is looked as the main one for CO 2 capture from flue gases. In this work, absorption solubility of CO 2 in aqueous solutions of four branched polyamines were determined at 313.15 K and 393.15 K using the constant-volume method combined with gas chromatography analysis. The relationship between molecular structure of these polyamines and absorption performance is discussed. It is found that the capture performance is affected by the number of amino groups, the carbon number between the amino groups and the chain length of polyamines. The corresponding values of CO 2 absorption heat were also estimated using the Gibbs-Helmholtz equation and were analyzed from the view of molecular conformation.
