Abstract

Compiled equations describing the experimental data of the liquid-vapor phase equilibrium in binary mixtures of carbon dioxide with methane and helium. Equations represents the dependence of liquid or vapor pressure from temperature and composition. At their compiling the program selected most significant coefficients of equation. Standard deviations of the experimental values of the pressure from calculated are equal from 3,0 to 4,1 %. Equations permits to determine the composition or temperature of phases at known values of  other parameters of the phase equilibrium.
