Vapour liquid equilibrium data for the 1,1,1,2 tetrafluoroethane (R134a) + dimethyl ether (DME) system at temperatures from 293.18 to 358.15K and pressures up to about 3 MPa up to about 3MPa
Isothermal vapour liquid equilibrium data have been measured for the binary system R134a +DME at five temperatures between 293.18 and 358.15 K, and pressures between 0.4899 and 2.9442MPa. The peculiarity of this system is the existence of an azeotrope with a minimum pressure, which disappears at 358.15 K. The experimental method used in this work is of the static-analytic type, taking advantage of two pneumatic capillary samplers (RolsiTM, Armines patent) developed in the CENERG/TEP Laboratory. The data were obtained with uncertainties within +-0.02 K, +-0.0001MPa and +-1% for molar compositions. The isothermal P, x, y data are well represented with the Redlich and Kwong equation of state using the Mathias Copeman alpha function and the Huron Vidal mixing rules involving the NRTL model.
