LIQUID-VAPOR EQUILIBRIUM IN MIXTURES OF NEON WITH KRYPTON OR XENON

Equations describing the experimental data of the liquid-vapor equilibrium in binary mixtures of neon with krypton or xenon have been worked out. These equations represent the dependence of liquid or va-por pressure from temperature and composition. The proposed form of the equation satisfies the limit condition and is suitable for the description of phase equilibrium in binary mixtures. At their compiling the program selected the most significant coefficients of the equation. The coefficients of the equations were determined from the experimental data obtained for these mixtures. This program provides a selec-tion of the most important factors of the equation. Standard deviations of the experimental values of the pressure from calculated are equal from 3.8 to 4.5%. Equations permit to determine the composition or temperature of phases at known values of the phase equilibrium other parameters.
