Using vapor-liquid interaction parameters to predict ternary vapor-liquid equilibrium data?
Thread Content
Aspen comes with binary interaction parameters, so how can ternary vapor-liquid equilibrium data be calculated? Given a pressure of 20 KPA, calculate the vapor-liquid equilibrium data for the water-acetic acid-ethanol ternary system? Seeking advice from experts! Thank you
The following post might be helpful for your question: How to obtain phase equilibrium ternary data such as NRTL from two-phase equilibrium data. http://bbs.hcbbs.com/thread-641786-1-2.html
The problem mentioned by a friend on the 2nd floor hasn’t been solved either. Is there anyone who knows how to handle it? Is there a relevant section for this, or is it necessary to use a flash tank for simulation?
The interactions between ternary systems are certainly much more complex than those between binary systems. To date, we have only seen measurement data for ternary and quaternary systems; no simulation results from software have been presented, except for those obtained by using software to perform regression on experimental data
I’ve seen people use Pro2 along with flash tanks and multivariable controllers to simulate ternary vapor-liquid equilibrium data, but I currently perform the regressions in Aspen software; therefore, I’d like to find similar calculations in A+ software
I have experimental data on the vapor-liquid equilibrium of a ternary system; how can I perform regression analysis for this ternary system? Does anyone have any advice?

Using binary prediction for ternary data. According to my supervisor. If he programs it himself, he can do it. If necessary, you can refer to Guo Tianmin’s book \"Multicomponent Vapor-Liquid Equilibrium and Distillation\"; moreover, using Aspen to perform direct regression on the parameters of ternary vapor-liquid equilibrium is likely to yield incorrect results.
