I have to create several tables with values of liquid densities (for generic hydrocarbon mixtures) at different temperature and pressures,
I use PRODE PROPERTIES and Excel,
the method =StrLD(stream,t,p)
returns directly the calculated liquid density at specified temperature and pressure,
for liquid density PRODE allows to specify different models as Extended PR or SRK or a EOS with Peneloux correction,
which is the best to adopt for hydrocarbon mixtures (C1...C13) in a range of temperature and pressures ?
It would seem that Extended PR or Extended SRK are more accurate that equivalent versions with Peneloux correction, is that true ?
