Which thermodynamic method to choose
Thread Content
The system consists of ethylene oxide, ethylene glycol, and water, which are separated through distillation; what thermodynamic method is suitable for this? Thank you
Has really no friend or colleague ever worked on this problem? It would be good to provide some information anyway. I don’t have any data at hand right now, so I don’t know where to start. The property method selection manual also does not provide much information about this system.
You can try using the NRTL method! Hehe
Either NRTL or Wilson will work, right?
I think the NRTL model can be used! For related questions, refer to \"Phase Equilibrium and Distillation Simulation Calculations for Special Systems\"! Hope this helps!
Also, this system needs to take into account the binding effect, right?
Where can I find this book? My email address is gu*nchun888@163.com. Please send one to me, thank you
I don’t have it on me right now! I’ll look for it for you tomorrow, okay! There seems to be a photocopy version online!

:) I haven’t read this book yet, but I’m already eager to send a letter of thanks. The people here are truly wonderful~~~ They answer all questions and share information~~~!!! I sincerely hope this forum will continue to thrive~~~ I wish everyone here happiness and good health~~~
UNIFAC, UNIQUAC, NRTL-RK, and WILSON are all acceptable.
Thank you to the person above for providing the books; they are very useful. This post was last edited by romaton on 2009-4-15 at 18:32.]
From the perspective of the separation system, it is a polar system; therefore, activity coefficient models such as NRTL or UNIQUAC can be used. As for which one is better, you can conduct a comparison...
There’s a chart on the forum that shows you how to choose the appropriate physical property method; you might want to take a look at it. Hey, good luck!
