HYSYS Selection of Property Package

[PetroBob]

Can anyone post a link to a website with a detailed explanation of which HYSYS property package is recommended for which types of fluids? My google search bogs down with a large number of sites showing how to select a property package (and not much explanation of which one to select). I'm personally only familiar with Peng-Robinson & ASME Steam.

My simulation has following components: Water, N2, CO2, CO, H2, H2S, O2, ethanol, minor organic solids

Thanks!

process simulators are quite complex tools to initialize and run, if you are not familiar with those models or the operating of your software I would suggest to consult a process engineer, read a good book or the operating manual where there is a good explanation...
For these reasons and simple problems (as those related to a design/rating of a valve) I prefer simple tools as Prode Properties which includes all the models you mentioned and are very easy and immediate to use...

if the CO2 is say over 20%, modified peng robison might be a good choice.

For the records I did find a more detailed explanation of property package selection in Appendix A of the Simulation Basis Guide:

Also I didn't intend to post this in valve engineering forum - whups! It should be in Chemical Plant Design or Process Engineering Forum.

I think what Paolo meant was - that in order to select property package you will benefit from a background in chemical engineering. Not to say that you cant get the knowledge otherwise - but there is a risk when using computer software as "black boxes" - your chances of spotting obvious and less obvious erroneous results becomes lower.
