“…The partial molar differences in enthalpy and entropy between the two states can be obtained by calculating the corresponding partial derivatives of the Gibbs free energy with respect to temperature The pressure range considered in this work is not too high to cause Henry's law constant to be a strong function of pressure and Henry's law is weakly dependent on pressure under the specified conditions. Therefore, it does not give rise to large errors if one ignores this pressure dependency [18,[21][22][23]. By means of this approximation and using equations (9)-(11), we estimated the thermodynamic functions of solution at infinite dilution for H 2 S and CO 2 in the IL.…”

“…diffusion coefficients of gases at various temperatures and pressures. In the past few years, a growing number of measurements reporting solubility and diffusion of CO 2 in various ILs have become available [5][6][7][8][9][10][11][12][13][14][15][16][17][18]. However, experimental data for the solubility and diffusion of hydrogen sulfide in ILs are scarce.…”

Alcohol amine solutions have a high absorption capacity and rate for CO 2 capture, however, there are some shortcomings such as high energy-consumption and low stability. To enhance CO 2 capture performance of aqueous MEA, a functional ionic liquid ([NH 2 e-mim][BF 4 ]) was introduced based on the advantages for CO 2 capture. Absorbents were prepared with the molar concentration ratio of [NH 2 e-mim] [BF 4 ] to the 30 vol% aqueous MEA of 0 : 10, 1 : 9, 2 : 8, 3 : 7, 4 : 6 and 6 : 4. The density and the viscosity of the investigated absorbents were measured and the effects of the molar fraction of [NH 2 e-mim][BF 4 ] (n I ) and temperature on CO 2 absorption performance were investigated. CO 2 desorption performance of the solvent at different temperatures was discussed. The stability performance of the absorbent with n I of 2 : 8 (I/M 2:8 ) was examined by five consecutive cyclic tests. The results showed that for pure CO 2 , the I/M 2:8 displayed the highest absorption performance at 303 K under 1 bar: a comparable CO 2 absorption capacity of the 30 vol% aqueous MEA and a higher CO 2 absorption rate at the later absorption stage.Moreover, with the increase of temperature, CO 2 absorption capacity and rate decreased, while CO 2 desorption efficiency and rate increased. 393 K was chosen as the optimum desorption temperature with the desorption efficiency of 99.31%. The introducing of IL contributed to CO 2 desorption performance of the absorbents significantly. The properties (CO 2 absorption capacity, mass loss, density and viscosity) of the I/M 2:8 during the cycles suggested that the IL-MEA mixture had an excellent stability performance.
