I have a question regarding a scenario where I am using 3 fluids that are found only in two different databases. I do not want to go into details (due to the proprietary nature of the simulation). So I will try to pharse my question in a general manner.
Suppose components A & B are in PR & B & C are better suited to be NRTL.
Now suppose that Stream_1_In = A+B is at some flow rate, temp. press. & mole fr., using 'PR'
Stream_2_In = B+C is at some other flow rate, temp. press. & mole fr. using 'NRTL'
If I use the UO: HE-000 which allows its own field for the PP, which one do I specify?
In reality I would expect (4.) to be irrelevent since the property, flash, enthalpy, etc calculations to be relying on the attached PP for the stream under consideration. Should it not?
Would you kindly shed some light here, please? Thank you.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
The "Property Package" option is common to all Unit Operations. In the HX case, it has no effect because the HX uses the PPs attached to the streams to do the calculations, to avoid heat balance issues due to different enthalpy basis between models.

Thank you for the reply. So it is just as I had expected ...
