It is an urgent act to limit greenhouse gas emissions to avoid the harmful effects of climate changes. In this work, the binary and ternary systems of guanidinium trifluoromethanesulfonate ([gua][OTf]) in N-methyldiethanolamine (MDEA) and/or water were examined as alternative solvents for gas treatment process. The thermodynamic properties including density, r, viscosity, h, thermal expansion, a p and physical solubility of CO 2 in the systems were measured as a function of molar composition with a temperature range of 293.2-333.2 K at 100-1000 kPa. The presence of [gua][OTf] accelerates CO 2 absorption process. The present study offers equations of correlation providing a reliable prediction of the binary and ternary systems as a function of concentration. The linear equation, quadratic equation, extended Arhenius equation and Henry's Law equation have been applied to assess the validity of the finding. The CO 2 solubilities in [gua][OTf] systems are found higher compared to other ILs in previous researches. Additionally, ANN modeling of the effective parameters was carried out and the composition of [gua][OTf] was proven as the key factor in maximizing the CO 2 solubility. 2014 Published by Elsevier B.V.

“…D w was obtained using an equation based on molecular volumes of the solutes and the solvent, as described in Othmer and Thakar (1953). This correlation was chosen because it was the only correlation able to predict the PZ diffusion with an acceptable error over the complete temperature range (Derks et al, 2008). In Table 4, it is possible to observe that for AHPD, the Hatta numbers are all greater than 2 and considerably lower than the corresponding infinite enhancement factor.…”

“…The influence of CO 2 on the viscosity and density is not considered in the model. The experimental viscosity of liquid phase is correlated by

\ln \frac{μ}{μ_{{normalH}_{2} normalO}} = a + M_{1} + M_{2} / T

with

M = b \cdot w_{MDEA} + c \cdot w_{PZ} + d \cdot w_{MDEA} \cdot w_{PZ}

where w is the mass fraction. Table lists the parameters for the viscosity correlation.…”

Numerical investigation on CO₂ absorbed in aqueous N‐methyldiethanolamine + piperazine

A multiphase and multicomponent mass transfer model of CO2 absorbed in aqueous N‐methyldiethanolamine and piperazine (PZ) was built in the study. In the model, a simple method of mass transfer between phases was proposed. Besides, the hydrodynamics, thermodynamics, and complex reversible chemical reaction were considered simultaneously. The model was validated by comparing with the previous experimental data which showed that simulated results can represent the experimental data with reasonable accuracy. Based on the model, the effects of gas velocity, liquid load and CO2 loading on the absorption rate, and enhancement factor were analyzed. Model results showed that the enhancement factor increased with a rising gas velocity while decreased with a rising liquid load or CO2 loading. The change of enhancement factor with CO2 loading was similar to that of equilibrium concentration of PZ which indicated that PZ was significant to the absorption process. Furthermore, the distributions of specie concentrations were discussed in detail. © 2016 American Institute of Chemical Engineers AIChE J, 63: 2386–2393, 2017
