Vapor-Liquid Equilibria and Dielectric Constants for Helium-Carbon Dioxide System

Details

• Description:
  Phase equilibria data are presented for the helium-carbon dioxide system at 253 deg, 273 deg, and 293 deg K, and pressures to 139 atm. Equilibrium is established under flow followed by nonflow conditions, and liquid and vapor samples are isolated without disturbing equilibrium. Liquid- and vapor-phase compositions are monitored with miniaturized capacitors, and compressibility factors are computed from resulting dielectric constants. The data are internally consistent and compare favorably with available literature values. [Description provided by NIOSH]
