Hydrate dissociation conditions for the refrigerants R116 (C(2)F6), R23 (CHF3), and their mixture R23/R116 (46:54 mass percent ratio) in the regions of hydrateaqueousvapor and hydrateaqueousliquid refrigerant equilibria were measured. The experimental measurements were performed within the pressure range of (0.45 to 9.2) MPa and the temperature range of (272.2 to 293.2) K. A thermodynamic model was developed for the prediction of the measured dissociation conditions. For this purpose, PRSV equation of state coupled with the MHV2 G(E)-EoS mixing rule along with the UNIFAC (original) activity coefficient and van der WaalsPlatteeuw (vdW-P) models were applied for the fluid and hydrate phases, respectively. The results show satisfactory agreement between the experimental and predicted values. The Kihara potential parameters for the refrigerants investigated were also obtained and are reported in this article.
