does the data regression procedure in Prode Properties allow to calculate/optimize BIPs for Vapor-Solid Equilibria ?

Which thermodynamic models / packages should I select for mixtures of natural gas plus carbon dioxide and a few other components ?

Thanks !

[serra]

you may follow the procedure and examples in manual (examples are provided for vapor-liquid and liquid-solid),

 

http://www.prode.com/docs/pppman.pdf

 

simply select SVE (Solid-Vapor Equilibria) instead of VLE / LLE /  SLE ...

 

for natural gas + CO2 and similar fluids probably a EOS (Peng Robinson) is Ok,

for solid model (CO2) I would consider a pure solid phase but 

other fluids may require different settings...

[mrbabu]

ah, thanks,

and (for pure solid phase) I set  molar fraction 1.0 (as for liquid-solid),  correct ?

Yes, for pure solids you can set phase fraction to 1
