Abstract
This Bureau of Mines report contains experimentally determined vapor- liquid equilibria data for a helium-nitrogen-methane mixture with a nominal composition of 15, 60, and 25 mole-percent, respectively. Measurements of the equilibrium phase compositions were obtained by means of a windowed cell, in conjunction with an automated chromatograph and a special analyzer for low helium concentrations. The data presented include a comprehensive table and eight graphs depicting phase compositions, vaporization ratios, and correlations with a previous study of two helium-nitrogen-methane mixtures of different compositions.
