  abstract = {Abstract The critical lines (temperatures and pressures) for the three binary mixtures ethane + sulfur hexafluoride (SF6), SF6 + propane, and carbon dioxide (CO2) + SF6, and the critical surface for the ternary system CO2 + ethane + SF6 were determined experimentally by a flow method. The binary data were compared to predictions using the predictive Soave-Redlich-Kwong (PSRK) group contribution equation of state (EoS). For the system CO2 + SF6, where no phase equilibrium information is available, the critical points were used to optimize the required PSRK group interaction parameters. Using these binary parameters, the ternary critical plane was predicted reliably.},

  abstract="Sulfur hexafluoride is a colorless, odorless, nontoxic, nonflammable gas that has a high dielectric strength and serves widely as an insulating gas in electrical equipment. At atmospheric pressures it sublimes directly from the solid to the gas phase and does not have a stable liquid phase unless under a pressure of more than 32 psia (221 kPa abs). It is shipped as a liquefied compressed gas at its vapor pressure of 298 psig at 70{\textdegree}F (2055 kPa at 21.1{\textdegree}C).",
