Equations describing the experimental data on liquid-vapor equilibrium in binary mixtures of methane with argon, carbon dioxide and helium have been compiled. The equations describe the dependence of pressure of liquid or vapor on temperature and composition. When compiling them, the program selected most significant coefficients of the equations. The standard deviations of experimental values of pressure from the calculated values range from 1.8 to 5.0%. The equations make it possible to determine the composition or temperature of the phases at known values of other parameters of phase equilibrium.
