Are there errors in the Aspen results?
Thread Content
Dear experts, I have been learning *Aspen recently, following the tutorials provided by Teacher Sun Lanyi. However, I’ve encountered several situations where the results I obtain by following the tutorials differ slightly from those given in the book; even for the same mass flow rate, there are discrepancies in the molar flow rates. As shown in the attached figures, I’m not sure what’s causing this. I would appreciate some guidance. I have compared each parameter of the two models, and they are identical; yet I’m not sure why the results differ. The difference isn’t significant, but I’ve encountered several such problems, and it feels frustrating. I hope some expert can help explain this
It is normal for simulation calculations to have errors; there’s no need to worry about it or waste time on it. Whether the results are accurate or not needs to be verified using experimental data or production data – simulation calculations are merely a tool.
The simulated values may have errors
