NIST Mixture Properties

The NIST Mixture Property Database calculates thermodynamic and transport properties of mixtures of fluids selected from any of 17 possible pure components. The emphasis of the database is on density prediction (especially for CO2-rich mixtures), but results for other properties and mixtures are also accurate.

All phase equilibrium calculations are performed with the Peng-Robinson equation of state, and coexisting phase properties are calculated with the NIST extended corresponding states model. Calculations can be performed for mixtures formed from any of 17 pure components. These include:

  • carbon dioxide
  • hydrocarbons
  • carbon monoxide
  • nitrogen
  • oxygen
  • hydrogen sulfide
  • argon
Calculated properties for any specified mixture include:
  • density
  • bubble point pressure
  • bubble point temperature
  • dew point pressure
  • dew point temperature
  • saturation properties
  • enthalpy
  • entropy
  • heat capacity
  • viscosity
  • thermal conductivity
