apetri,
thanks for the information,
I agree that GERG models are preferable due to "wired" parameters (while in other cases some VLE points and data regression may be required),
in my case I suppose that differences (PR vs GERG models) may be due to PR parameters,
I load the Kij from Prode...
we have a realtime control on dew point specs based on Prode Software,
our gas includes C1-C6+ .. CO2, N2, H2S ... 0.005 H2O (no free water)
actually GERG 2008 is selected for VLE indicating water and some C6+ fractions as first components to condense,
comparing results with Peng Robinson...
thanks all for the help,
delittle, I know Prode but I was not aware of the link with Mathcad 15,
seems a interesting stuff, hoping it will be available soon.
IRstuff, I need to solve iteratively, a table doesn't give the required accuracy, I could calculate the properties with a equation os...
can you recommend a Mathcad resource for calculating thermophysical properties and phase equilibria of mixtures with different fluids ?
I need the values of properties as enthalpy, entropy and others,
actually I enter the data manually which is tedious,
with Google I have found many resources...
