Where do the binary interaction parameters in Aspen come from?
Thread Content
Regarding the sources of the binary interaction parameters, some values listed in the software are R-PCES, APV84 VLE-IG, APV84 VLE-RK, APV84 VLE-HOC, APV84 VLE-LIT, etc. What do these sources mean? How to choose and determine which library’s parameters are appropriate?
It’s just the fitting parameters collected from different databases. To check whether the parameters are appropriate, one can view the details in the database to see the applicable range for pressure, flow rate, and concentration.
I have another question: how do I search in a database? I really want to check whether the temperature and pressure range is appropriate.
In the APED manager
Hello, I searched in the software for a long time but couldn’t find it. . . ~Could you be more detailed?
The shortcut is Database Manager - Aspen Properties V8.4, and the file name is APDBMGRV84.msc
To obtain accurate binary interaction parameters, data must be gathered through experiments; if one wants to simulate the process roughly, it is sufficient to use appropriate property equations with default values. I didn’t expect to run into you here, old classmate.
Who are you? I registered an account using my name.
To determine whether it is appropriate, it needs to be compared with the actual parameters.
Uh, I still can’t remember~~ Who is it?
