“…Density, sound velocity and refractive index values obtained for pure water and pure DME are shown in Table 1 and compared with literature data [9][10][11][12][13][14][15][16][17][18] while, in Table 2, experimental values for these quantities in water + DME mixtures are shown. In all cases, subscript 1 corresponds to water and subscript 2 is attached to DME.…”

Density, sound velocity and refractive index of binary mixtures of water + 1,2-dimethoxyethane mixtures were measured over the whole composition range and at the temperature interval from 293.15 to 323.15 K. Obtained density data for the pure components agree, within experimental error, with published values. However, in the case of binary mixtures, strong discrepancies with values calculated from the equation proposed in the literature for this system are found. Excess functions, isentropic compressibility coefficients and thermal expansion coefficients were calculated from experimental data. Partial molar volumes were obtained employing the exponential representation previously proposed by us which shows better results than the usual polynomial approach. Results are discussed on the grounds of the molecular characteristics obtained from Raman and NMR spectroscopy determinations on this system.

“…Figure 5 shows the evolution of this parameter during the experiments. 16,17 The AP (primary) solvent has shown, in a previous work, 18 that the main reaction product is bicarbonate ion thought in the first part of experiment the existence of carbamate was detected. Taking into account the different reaction pathways between carbon dioxide and amines, it is possible to conclude that the main reaction product is the bicarbonate ion.…”

Present work includes research about the influence of the type of amino group using one or two amine molecules on carbon dioxide chemical absorption using aqueous solutions of alkanolamines and diamines. A comparison of chemical absorption processes using aqueous solutions of two individual diamines (3‐(dimethylamino)propan‐1‐amine and 1,3‐diaminopropane) and a mixture of amines (3‐amino‐1‐propanol and 3‐(dimethylamino)propan‐1‐ol) is reported including absorption rate curves, carbon dioxide loading, reaction mechanism or solvent regeneration to obtain useful information about the quality of each solvent for carbon dioxide separation. In general, amines blend of 3‐amino‐1‐propanol and 3‐dimethylamino‐1‐propanol, have shown a better behavior than their individual amines. Diamines and mainly 3‐dimethylamino propylamine that presents primary and tertiary amine groups in its structure, have led similar results. After these studies, 3‐dimethylamino propylamine, can be considered an appropriated amine to industrial carbon dioxide absorption process. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2702–2710, 2018

Accurate representation of the physical properties of a solvent is essential for design and simulation of processes. Density and viscosity, for instance, have an important role in modelling and designing absorption and desorption towers. In the present work, a model to accurately calculate the density of aqueous amine solutions used in CO 2 capture was developed as a function of temperature and composition. The model is based on excess Gibbs energy functions, and in this work the functional form of the non-random two-liquid (NRTL) model was used. The model is able to accurately represent the density of the tested systems with deviations below 0.2% for most cases. The pure component density was calculated using the modified Rackett equation with the parameter Z RA as a function of the temperature and pressure of the system. The calculated deviation (AARD) for pure component density was below 0.09%.
