Experimental Measurement and Modeling of Phase Diagrams of Binary Systems Encountered in the Gasoline Desulfurization Process Using Ionic Liquids

Abstract

The aim of this work is to investigate phase equilibrium of binary systems encountered in the extractive desulfurization of gasoline and diesel using ionic liquids. This work is focused on two ionic liquids: 1,3-dimethylimidazolium methylphosponate [DMIM][Ph] and 1-ethyl-3-methylimidazolium thiocynate [EMIM][SCN]. Vapor-liquid equilibrium (VLE) measurements on binary systems of ionic liquids with various solutes including thiophene, pyridine, toluene, and water at pressures close to the atmospheric pressure were performed and correlated by the PC-SAFT equation of state. The molecular parameters of pure ILs were determined from experimental density data, whereas binary interaction parameters k(ij) were optimized on experimental VLE data. The eight binary mixtures: \thiophene+ILs\, \pyridine+ILs\, \toluene+ILs\, and \water+ILs\ studied in this paper were accurately described by the PC-SAFT equation of state.
