Today, in the oil and petrochemical industries, deep eutectic solvents are used as a new generation of green and efficient solvents for separating azeotropic compounds. These solvents are biocompatible and economically viable. In this separation method, the deep eutectic solvent has a higher solubility power for the target compound (the extractable component) compared to other components in the mixture. In this study, the separation of the azeotropic compound benzene + heptane as aromatic and aliphatic hydrocarbons using synthesized deep eutectic solvents (choline chloride/urea, choline chloride/glycerol, choline chloride/ethylene glycol, choline chloride/propane diol) has been investigated. Thermodynamic modeling of the extraction process has also been performed using the NRTL thermodynamic model. The results of the benzene extraction from heptane showed that the selectivity of deep eutectic solvents is larger than the unit and economically suitable for industrial extraction units. Additionally, the modeling results showed that the NRTL model accurately matches the equilibrium data of the mentioned binary systems.
