    natural gas VLE, thermodynamic model selection with Prode Software

    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...

    natural gas VLE, thermodynamic model selection with Prode Software

    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...

    thermophysical properties in Mathcad

    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...

    thermophysical properties in Mathcad

    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...
