Hydrate dissociation conditions for the systems of CO2 + water + {NaCl or CaCl2 or MgCl2} + cyclopentane (CP) were investigated at various salt molalities of (1.041-4.278) mol.kg(-1) in different temperature ranges of (261.1-287.2) K and in different pressure ranges of (0.813-3.239) MPa. The dissociation conditions were measured by means of an isochoric pressure-search technique. The main challenge is limited information on the utilization of hydrate technology for industrial wastewater treatment and desalination processes, mainly with a water-immiscible promoter. A promoter is a substance that is used to increase hydrate dissociation temperatures or lower dissociation pressures. The main aim of this study was to produce hydrate dissociation data for the design/optimization wastewater treatment and desalination processes using gas hydrate technology. The measured hydrate dissociation data were successfully modeled using the Hydrate Electrolyte-Cubic Plus Association (HE-CPA) equation of state-based model.
