do you have an idea of accuracy of solid (mixture) models to predict pour point ?

I utilize the wax model to predict cloud point, 

can I adopt the same (model) for both ?

Thanks.

the solid models in Prode Properties are accurate within a few degrees

but final results will depends (mainly) from the methodology utilized to characterize the mixture,

(you should adopt the procedure included in Prode),

 

for petroleum fractions I would use two (separate) models.

thanks Paolo,

do you know if Prode models can account for solvents ?

[PaoloPemi]

yes, if you know how to model these components,

for example with a EOS,

for chemicals you may need to tune the model,

for  the details see the SLE data regression example in the manual.
