Hello Daniel,
I wanted to simulate a heat exchanger which has cold fluid 30% by mass aqueous NaOH solution and hot fluid condensing steam. I am using Reaktoro property package for the cold fluid and Steam table for steam. Since there will be partial vaporization of cold stream, I wanted to ask whether Reaktoro supports vapor-liquid calculation or not. Upon simulating with Calculation type as: "Specify Outlet Molar Vapor Fraction (Stream 2)", I am getting the error: "Unsupported Vapor Pressure Calculation".
I am attaching the photo containing error and specifications given to heat exchanger.
Thank you
The Reaktoro Property Package doesn't support direct partial vaporization calculations, i.e. when you specify pressure or temperature and a vapor fraction higher than zero.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Ohk. Thanks for the feedback. What property package would you suggest for NaOH + Water mixture?
