Results for the experimental determination of vapor-liquid equilibrium data in argon, oxygen, and nitrogen mixtures are presented. The experimental apparatus and procedures are described. The experimental data at 26, 23, 20, 18, 16, 14, 12, 10, 8, 6, 4, 2 and 1 atmosphere levels are presented. A correlation of our experimental data is made. Plots and tables of equilibrium constants, relative volatilities and activity coefficients are presented. Experimental and calculated results are compared and a comparison of the data to the literature is made. Analytical enthalpy data is presented. The correlation reproduces the experimental data with an error less than 2.5 being worst at 20 atmospheres and best at 6 atmospheres.
