“…Comparison of the results obtained using MDE with our previous work based on GA (Vatani et al 2012) shows that MDE is a very reliable algorithm in parameter estimation problems which can give more accurate results compared to GA. Abbreviation, full names and list of ternary ionic liquid systems used in this study is given in Table 1.…”

“…They also reported their data and compared their data for various systems (including vapor liquid equilibrium, vapor-liquidliquid equilibrium, and liquid-liquid equilibrium) form the literature. In some other studies, GA was successfully applied for estimation of interaction parameters of other complex models for systems of LLE containing ionic liquids and also for modeling of viscosity of crude oil binary blends (Vatani et al 2012;Vakili-Nezhaad et al 2013;Vakili-Nezhaad et al 2014;Al-Maamari et al 2015).…”

A modified differential evolution algorithm (MDE) has been used for solving different process related design problems (namely calculation of the NRTL and Two-Suffix Margules activity coefficient models parameters in 20 ternary extraction systems including different ionic liquids and reactor network design problem). The obtained results, in terms of root mean square deviations (rmsd) for these models are satisfactory, with the overall values of 0.0023 and 0.0170 for 169 tie-lines for NRTL and Two-Suffix Margules models, respectively. The results showed that the MDE algorithm results in better solutions compared to the previous work based on genetic algorithm (GA) for correlating liquid-liquid equilibrium (LLE) data in these systems. MDE also outperformed DE algorithm when tested on reactor network design problem with respect to convergence and speed.

Parameter estimation problems for liquid-liquid equilibrium data modeling are challenging due to the nonlinearity of thermodynamic models. In this work, the stochastic global optimization technique, namely Genetic Algorithm is applied to calculate the interaction and non randomness parameters of NRTL model. Forty ternary extraction systems containing benzene, hexane and different ionic liquids as solvent at various temperatures reported in literature are selected. The parameters of NRTL model are calculated and the global rmsd value of 0.0076 for 357 tie-lines shows that these parameters can be considered as the global parameters of NRTL model in the studied ternary systems. The global parameters are applied in all systems and rmsd values for them are reported. The results showed that Genetic Algorithm as a powerful and effective tool can be used to optimize highly nonlinear problems in phase equilibrium modeling.
