Hi Again,
Sorry, but I doubt NH3 is the reason. NH3 is not a valid component at all for use with Amine package. It cannot handle NH3. HYSYS does not allow one to select it with the package. How did you manage to select NH3 in the simulation basis manager?

Hi Mondolfi,
Maybe it is late, but have you traced the problem back to the exit streams of the absorber?
You can easily check validity of your absorber solution if you calculate rich amine loading. It must be something like 0.35. Li-Mather is much stronger in prediction, but K-E is also good...
Hi Mondolfi,
I could not find the above-mentioned thread. Anyway, I am very much interested in your case. I am pretty sure that converging a regenerator is fairly easy. Can I help?

Hi Sadiel,
If you mean mixing ethanol in a number of proportions to examine the resulting ON, you must first build as many streams as are needed with different compositions (or use HYSYS mixer U-Op), which you certainly know how to do. Then, you must assign an equal number of Cold Properties...
dbevil,
I know that HYSYS.Plant (www.Hyprotech.com) is used in similar projects. It is a dynamic simulator with extensive steam property packages (NBS and ASME) and two-phase flow modeling capabilities included.
It is in fact a process simulator but you can still use its PIPE operation for...
