Aspen plus HF modeling

[SanV]

I am currently modeling an acid flue gas cooling and cleaning process.

I am specially interested in the Fluoride removal. I wish to know in which extend is the Aspen integrated gas-phase equation of state for HF able to model the equilibrium behavior.

I am not sure about the use of the flue gas data package, or about the HF-H2O data package.

If anyone can lend me a hand it would be great

Thanks in advance

You mention gas cleaning.
If that would be wet scrubbing I would go for the EHF insert. It is good for concentrations as high as 70% in the gas phase.
I think, but have not checked that the HF <--> H2F2 dimerization is accounted for, not ny creating the H2F2 specie but by the parameters. I used the EHF for a wet scrubber design.
For scrubbing, it will not be very important, what you want is proper equimlibrium at the low concentrations.
The best you can do is, if accuracy is critical over a large range, is to generate the x-y table flashcurve and check against litterature. For a preliminary design, I would use directly the EHF insert.
