“…Therefore, those properties for ionic liquids have to be estimated. We used the modified Lydersen-JobackReid group contribution method proposed by Valderrama et al [41] to estimate the critical temperature and pressure and the acentric factor of the ionic liquids studied. The estimated values of the properties for the ionic liquids studied in this work are given in Table 2 along with those for CO 2 .…”

Solubility data of carbon dioxide (CO 2 ) in two pyrrolidinium-based ionic liquids: 1-butyl-1-methylpyrrolidinium dicyanamide ([bmpyr][dca]) and 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([bmpyr] [Tf 2 N]) are presented at pressures up to about 30 MPa and temperatures from 303.2 K to 343.2 K. The solubility was determined by measuring bubble or cloud point pressures of mixtures of CO 2 and ionic liquid using a high-pressure equilibrium apparatus equipped with a variable-volume view cell. The CO 2 solubility in the ionic liquid in terms of the mole fraction or the molality increased with the increase of the equilibrium pressure at a given temperature, but decreased with the increase of temperature at a given pressure. At a given temperature, the mole fraction of CO 2 dissolved in the ionic liquid increased rapidly as pressure increased. CO 2 solubility in the mole fraction almost reached saturation around 0.65 for [bmpyr][dca] and around 0.8 for [bmpyr][Tf 2 N], respectively. The experimental data for the CO 2 + ionic liquid systems were correlated using the Peng-Robinson equation of state (PR-EoS). The mixing rules of the WongSandler type rather than the classical mixing rules of the van der Waals type were coupled with the PR-EoS. The resulting modeling approach proved to be able to correlate the CO 2 solubilities in aforementioned ionic liquids over the aforementioned range of temperature and pressure within 5% average deviations.

The objective of this study is to develop a model to determine the thermal conductivity of pure ionic liquids and Ionanofluids. In order to estimate the thermal conductivity of pure ionic liquids, a group method of data handling model is proposed based on 23 ionic liquids corresponding to 216 experimental data points.The average absolute relative deviation for all studied systems was 1.81%, which is a satisfactory degree of accuracy for the proposed model. Furthermore, the Maxwell model is modified to correlate the thermal conductivity of Ionanofluids as a function of temperature and volume fraction of nanoparticles. The average absolute relative deviation for this model is 0.61%. Additionally, Maxwell and modified geometric mean (mGM) models are used to evaluate the models that * Corresponding predict the thermal conductivity of Ionanofluids. The results show that mGM is more accurate for prediction of thermal conductivity of Ionanofluids.
