ABSTRACT
Vapor-liquid equilibrium (VLE) data for the ethane (R170) + hexafluoroethane (R116) system were measured at temperatures of (199.64, 213.06, 228.28, and 242.93) K. The measurements were carried out with an apparatus based on the recirculation method. The measured VLE data for this binary system of R170 + R116 show azeotropic behaviors at certain compositions. The experimental results were correlated with the Peng-Robinson equation of state using the Panagiotopoulos-Reid mixing rule.
