Thermodynamic Method for H2SO4, NaOH etc.
Thermodynamic Method for H2SO4, NaOH etc.
(OP)
Hello There,
I am doing some simulation stuff (proII, chemcad) dealing with NaOH and H2SO4. After the simulations, I compared the viskosities of them with real values. They are both far away from the real values. In the column dynamics this could have a massive impact. NRTL is the most successful model until now, however not satisfactory.
My Question: Is there better methods available or is there a possibility to correct the original thermodynamic entry.
thanks.

However to just tweek some liquid viscosities, thermal conductivities, etc, can easily be done in any simulation package. Density is another one that can be fairly easy to tweek for use with NRTL.

I knew about the OLI Package but I am not sure the IT budget will allow that upgrade. Does ist really do its work?
and maybe anyone could tell me how to tweek the thermodynamics with which values?
