Abstract

The present research provides data on the density (ρ), viscosity (η) and ability to absorb carbon dioxide of systems containing amine, molecular solvent (MS) and choline chloride (ChCl), with the investigation of the physical properties of both neat amine/MS/ChCl mixtures and their samples after complete CO2 saturation. The effect of the mixture composition was studied by varying amine from primary (monoethanolamine, MEA) to secondary (diethanolamine, DEA) and tertiary (triethanolamine, TEA) amine, and the degree of its substitution from a mono- (MEA, DEA and TEA) to a doubly-substituted (ethylenediamine, EDA) compound. The role of an MS was investigated via the exchange of ethylene glycol (EG) with water and dimethylsulfoxide (DMSO). In addition, the influence of the CO2 absorption promoters present in the ternary MEA/EG/ChCl mixture at an amount of 5 wt. % was also investigated. We show that an increase in ρ and η in the amine/EG/ChCl mixture affects the properties of neat amines. This suggests that in the studied ternary mixtures, the nature of the interspecies interactions is very similar to those in the previously studied MEA/EG/ChCl system. When EG was exchanged for H2O or DMSO, a decrease in ρ and an increase in η were observed. A comparison of the data with the corresponding properties of the systems composed of each pair of the mixture components indicates that the intensity and/or number of interspecies interactions in the present ternary mixtures were stronger than those in pure H2O, DMSO and MEA. While in the presence of promoters no significant changes in the studied properties were found, for the corresponding CO2-saturated samples, the ρ and η increased proportionally to the amount of absorbed gas. This was also the case for all the systems studied in the present research. The overall CO2 absorption of the EG-based mixtures decreased when going from primary to secondary and tertiary amines; it was 21% higher for the MEA/H2O/ChCl system compared to the mixtures containing EG and DMSO, which, in turn, showed similar absorption capacities. When the promoters were added to the MEA/EG/ChCl mixture, the highest capacity was found for the piperazine-containing system. [ABSTRACT FROM AUTHOR]

26. Development of Multifunctional Choline-Like Ionic Solvents for Ammonia and Carbon Dioxide Capture and Transformation of Latter

Author

Markin, Zakhar A., Golovacheva, Anna A., Otvagina, Ksenia V., Petukhov, Anton N., Markov, Artyom N., Logunov, Alexander A., Atlaskin, Artem A., Esipovich, Anton L., Vorotyntsev, Andrey V., and Kazarina, Olga V.

Abstract

This study developed two ionic solvents using chlorides from the choline (ChCl) family: ammonium salts with 2-hydroxyethyl groups, dimethyl-di(2-hydroxyethyl)-ammonium chloride (1) and methyl-tri(2-hydroxyethyl)-ammonium chloride (2) as the hydrogen bond acceptor (HBA) and glycerol (Gly) as the hydrogen bond donor (HBD) in a molar ratio of 1:2. The solubility of ammonia and carbon dioxide in these solvents and also solubility of carbon dioxide in glycelin (ChCl : Gly = 1:2) and pure glycerol were measured at temperatures ranging from 303.2 to 333.2 K and pressures from 100 to 813 kPa. From this, Henry’s law constants and the changes in thermodynamic functions during the absorption process were determined. We show that solubility of ammonia and carbon dioxide in these ionic solvents made from 2-hydroxyethyl-grafted hydrogen bond acceptors (HBAs) increases with the number of 2-hydroxyethyl groups compared to the glycelin comprising HBA with one 2-hydroxyethyl substituent only. Developed fluids also demonstrated catalytic activity in the cycloaddition of CO2to epichlorohydrin (ECH), producing chloropropylene carbonate (PC-Cl). Under reaction conditions of 100 °C, 650 kPa, and 2 mol % catalyst concentration, a 95% conversion of ECH was achieved within 6 h. The effect of various reaction conditions on the ECH conversion and PC-Cl yield was also investigated. Additionally, the densities (ρ) and viscosities (η) of both pure and gas-saturated fluids were measured, completing the comprehensive characterization of the ionic solvents.

Abstract

The present study is concerned with a complex theoretical and experimental evaluation of the effect of various distribution coefficients on the hydrate crystallization process retrofitted with/without membrane in the process of the capture of carbon dioxide from flue gas (N2(83.13 mol.%)/CO2(16.87 mol.%)) at the low-pressure. A batch reactor with a stirrer was used to perform experiments under isothermal conditions of 275.5 K and initial pressure of 3.1 MPa, the aqueous solution with a TBAB concentration of 5.0 wt% in the presence of the 1500 ppm Tween-80 were tested. The following modes were studied: the pressure-dropping separation, separation at the constant pressure, and the continuous hydrate separation. The continuous hydrate separation with/without a membrane was modeled, and its experimental verification was carried out. It was shown that using a two-stage hydrate membrane technology with an increase in the distribution coefficient, the CO2capture cost per ton decreased and could reach 35 $/ton, with a 92 % CO2recovery and a CO2residue flow of 0.4 mol.%.

31. Monoethanolamine + Ethylene Glycol + Choline Chloride: An Effect of the Mixture Composition on the CO2Absorption Capacity, Density, and Viscosity

Abstract

In the present paper, a systematic investigation of the influence of amine and salt concentration on the CO2absorption capacity (mCO2, moles of CO2absorbed by 1 kg of a solution) and amine efficiency (cCO2, moles of CO2absorbed by 1 mole of amine) of the ternary mixtures composed of monoethanolamine (MEA), ethylene glycol (EG), and choline chloride (ChCl) was carried out. We demonstrate that, in general, the presence of a fixed amount of ChCl in a mixed {MEA + EG} solvent cannot improve mCO2over an entire range of solvent composition and weakly decreases cCO2with the effect more pronounced for the mixtures containing greater amount of MEA. The influence of ChCl concentration on the above properties was analyzed for the mixtures with a fixed MEA/EG mole ratio but various ChCl concentrations. It was shown that a decrease in mCO2observed with an increase in ChCl, again, is rather caused by an overall decrease in MEA content in a mixture as its efficiency cCO2does not change when ChCl concentration increases. In addition, properties such as density (ρ) and viscosity (η) of the binary {MEA + EG} and ternary {MEA + EG + ChCl} mixtures were obtained within a wide range of temperatures for both neat and CO2-loaded samples. We show that regardless of the {MEA + EG} mixed solvent composition, the presence of ChCl increases both ρand η. For CO2-loaded samples, both properties increase significantly with a greater contribution for the mixtures containing greater amount of MEA.
