NIST Hydrocarbon Mixtures (SUPERTRAPP)

This powerful database (also known as SUPERTRAPP) predicts thermodynamic properties of pure fluids and fluid mixtures of up to 20 components. The components are selected from a database of 116 components, mostly hydrocarbons. Liquid natural gases can easily be modeled. SUPERTRAPP performs phase equilibria calculations and gives the thermodynamic properties of all phases and the feed.

Thermodynamic properties include:

  • density
  • compressibility factor
  • sound speed
  • Cp
  • Cp/Cv
  • enthalpy
  • entropy
  • Joule-Thomson coefficient
Transport properties include:
  • viscosity
  • thermal conductivity
SUPERTRAPP allows the user to:
  • perform bubble point pressure calculations
  • perform dew point pressure calculations
  • perform isothermal flash calculations
  • obtain properties of pure components along the saturation boundary
  • produce tables of properties along isobars or isotherms
  • change units
  • add a new component not in the current database
  • enter data from the keyboard or from data files
