I'm performing an assignment with PRO/II, H2 process with amine sweetening process.
If I want to make amine sweetening process in Aspen HYSYS, there is an separator(absorber, ...) for amine process, and I can use these.
But in PRO/II, I can use only some columns (distillation, shortcut, side column), and I CANNOT find a way to express amine sweetening process with these columns.
In many references with amine process, all they use only distillation columns (as absorber and regenerator) to separate CO2.
I tried to make similar process with their input value in about hundreds times, but I could not make their process.
