pro2 azeotrope

This post was last edited by suiran983527 on 2009-6-10 17:19 How to get azeotrope information from pro2? In other words, how do I know if there is an azeotrope forming in my system of matter? In addition to that BVLE, can you get detailed information about the azeotrope, such as data tables such as the azeotrope temperature at a certain pressure?

1. Look at the gas-liquid equilibrium curve. The direct method can only look at the binary system. 2. Check the azeotropic information of TDM. In addition, with aspen plus, binary and ternary, you can directly get the azeotrope results through azeotrope query, which is very convenient.
Haha thanks for being so timely. Also, there is a question that I have never been clear about.: In Pro, what will happen if a system of matter does not form two liquid phases, but when the window appears when selecting an equation, you choose to handle liquid-liquid equilibrium? Will erroneous results occur? This post was last edited by huanglei on 2009-3-29 19:23 ]
I haven't tried this, but I know it must be wrong. Calculating liquid-liquid balance requires calculating the activity coefficients of two liquid phases, while gas-liquid balance generally calculates the activity coefficient of the liquid phase and the fugacity coefficient of the atmosphere.
You can find an example and try it. There will be a breakpoint on the gas-liquid balance curve. You will know if it will affect the actual calculation.
