Carbon Dioxide Thermodynamic tables

  1. Aug 24, 2010 #1

    In my old papers, I could find a nice P-T diagram for Carbon Dioxide.
    I am interrested in liquid-gas equilibrium data, specially enthalpy and internal enery.
    Unfortunately, the diagram doesn't fit very well my current purpose.
    Moreover, I would like to make more use of my computer and less use of my nice diagram.

    Would you know where I could find the equations describing the CO2 phase diagrams,
    specially the thermodynamic function for liquid-gas equilibrium?
    As you may guess, a source code would be even more attractive (if for free).

    Thanks a lot for you suggestions,

    I usually use programs like EES or Refprop, but EES does cite it's source for CO2 properties:

    R. Span and W. Wagner, A New Equation of State for Carbon Dioxide Covering the Fluid Region from the Triple-Point Temperature to 1100 K at Pressures up to 800 MPa, J. Phys. Chem, Ref. Data, Vol. 25, No. 6, 1996.

    Thanks a lot, Yeti08 !

    I could find your reference on Nist.
    In addition, by googling further I could find "Propath" there:

    http://www.fkm.utm.my/~mohsin/sme1413/property.tables/propath/ [Broken]

    It is based on the Span and Wagner formulas.
    It took me less than an hour to solve my problem in Excel/VBA, thanks to your initial reference.

    By the way, are you using Propath, or another library or your own programming?
    The Propath source code is in good old Fortran, which is not my preferred language any more.
    I would be interrested in source code in Java or in C#.
    Fortran to Java is not really an easy translation.
    Would you eventually know where such source code would be available?

    Thanks again,
