If I have a mixture of NaOH and water which thermodyamic model could I use in Aspen Plus?
I think the ENRTL is the most suitable.
What are your thoughts on it?

Hi,

Yes NRTL!

Note: Right time to review the supportive documents given to you or Aspen Help.

Use the Assistant in Aspen+ properties, it will lead you to their recommended method.

Hi Breizh, yeah indeed NRTL together with electrolyte, which iw ENRTL.

Btw Breizh,

Very nice document.
I am looking for a document which has a good summary and explanation of all these thermodynamic models. There is a very nice chapter in Robins book.

Hi,

Pitzer could be an option, I will start with eNRTL.
