In this work an equation of state (EoS) based on Perturbed Chain SAFT has been used to correlate the phase behaviour of ionic liquid+hydrocarbon systems. Pure component parameters for ionic liquids have been adjusted using available experimental data in the literature, then liquid-liquid equilibrium experimental data were correlated just utilizing one binary interaction parameter. The results showed that the presented model can be useful for phase equilibrium calculations in a wide range of temperature and pressure.
