The solubility of carbon dioxide (CO 2 ) in three different ionic liquids (ILs):and 1-benzyl-3-methylimidazolium 1,1,2,2-tetrafluoroethanesulfonate ([BNMIM][TFES]) were measured. Measurements were done at temperatures ranging from 303.2 to 373.2 K (323.2 to 373.2 K for [BNMIM][TFES]) at pressures from 0.80 to 36.80 MPa. Measured data show that pressure, temperature, and characteristics of cation of ILs ([EMIM], [BMIM], and [BNMIM]) affect its CO 2 solubility. We determined the CO 2 solubility of fixed CO 2 mole fractions for three ionic liquids. Among the three ILs, CO 2 solubility intensity was ranked. The Peng− Robinson equation of state, the conventional van der Waals one-fluid mixing rule, and the modified Lydersen−Joback−Reid method were used to correlate the experimental data. The average absolute deviations of pressure were 0.0164 for CO 2 + [EMIM][TFES], 0.0361 for CO 2 + [BMIM][TFES], and 0.0251 for CO 2 + [BNMIM][TFES] systems.

“…In order to develop reliable models, it was crucial to use a large number of experimental data points representing a variety of conditions. In the current work, 744 experimental data points for carbon dioxide solubility in 13 different ILs (36 to 80 points for each IL) were collected from the literature [40][41][42][43][44]. Table 1 presents the references from where the data were gathered and the observed range of experimental measurements.…”

“…The current work aims at developing highly robust and easy-to-use machine learning models that can be applied for forecasting the solubility of CO 2 in 13 different ionic liquids at different temperature and pressure conditions. Two rigorous connectionist techniques, namely multilayer perceptron (MLP), and gene expression programming (GEP) are applied on a set of experimental data that was gathered from different literature sources [40][41][42][43][44]. The MLP method was optimized using either Levenberg-Marquardt (LMA) or Bayesian Regularization (BR) techniques.…”

Estimating the solubility of carbon dioxide in ionic liquids, using reliable models, is of paramount importance from both environmental and economic points of view. In this regard, the current research aims at evaluating the performance of two data-driven techniques, namely multilayer perceptron (MLP) and gene expression programming (GEP), for predicting the solubility of carbon dioxide (CO 2 ) in ionic liquids (ILs) as the function of pressure, temperature, and four thermodynamical parameters of the ionic liquid. To develop the above techniques, 744 experimental data points derived from the literature including 13 ILs were used (80% of the points for training and 20% for validation). Two backpropagation-based methods, namely Levenberg-Marquardt (LM) and Bayesian Regularization (BR), were applied to optimize the MLP algorithm. Various statistical and graphical assessments were applied to check the credibility of the developed techniques. The results were then compared with those calculated using Peng-Robinson (PR) or Soave-Redlich-Kwong (SRK) equations of state (EoS). The highest coefficient of determination (R 2 = 0.9965) and the lowest root mean square error (RMSE = 0.0116) were recorded for the MLP-LMA model on the full dataset (with a negligible difference to the MLP-BR model). The comparison of results from this model with Appl. Sci. 2020, 10, 304 2 of 18 the vastly applied thermodynamic equation of state models revealed slightly better performance, but the EoS approaches also performed well with R 2 from 0.984 up to 0.996. Lastly, the newly established correlation based on the GEP model exhibited very satisfactory results with overall values of R 2 = 0.9896 and RMSE = 0.0201.
