ABSTRACT

Isothermal vapour-liquid equilibrium data have been measured for the RE170 + R3-1-10 binary system at nine temperatures between 313.28 and 392.83 K, and pressures between 0.57 and 4.9 MPa. The experimental method used in this work is of the static-analytic type, taking advantage of two pneumatic capillary samplers (ROLSI [TM], Armines patent) developed in the CEP/TEP laboratory. The data were obtained with accuracies within +-0.02 K, +-0.0006 MPa and +-0.009 for molar compositions. The particularity of this system is to present an azeotrope. The isothermal P, x, y data are well represented with the Peng and Robinson equation of state using the Mathias Copeman alpha function and the Wong-Sandler mixing rules involving the NRTL gE model.
