     electrolyte cubic square-well equation of state, ecsw eos, based upon the helmholtz free energy consists of the one non-electrolyte term and the two electrolyte terms. the non-electrolyte term is cubic square-well equation of state (csw eos) and the two electrolyte contributions consist of a born energy and the mean spherical approximation terms. in this work, ecsw eos is coupled with the van der waals-platteuw model and applied to predict the hydrate dissociation pressures of the methane+ ionic liquid+ water systems. ferthermore, the adjustable paramers of the imidazolium based ionic liquid solutions calculated by using experimental data in litreture.a good agreement between the results of the model with the experimental data indicates the reliability of this model to predict the hydrate equilibrium conditions.
