Vapor-liquid equilibria data for 65-34-1 and 25-27-48 mole-percent helium-nitrogen-methane mixtures are presented for 12 temperatures from 76.5 deg to 164 deg k and pressures from 100 to 1,200 psia. These data were obtained in a windowed phase-equilibria cell equipped with a vapor recirculating pump. Isobaric and isothermal k- values are plotted for both mixtures. Two isometric plots are included.
