Or about MDEA desulfurization and decarbonization?

In the actual process, under what gas volume or under what circumstances should one tower be used for absorption (that is, only lean liquid is used), and under what circumstances it can be absorbed in stages. Semi-lean liquid is used in the lower tower and lean liquid is used in the upper tower. Thank you.
This is a practical operation. You don’t have to input it into the software to simulate this. You have to ask an experienced engineer with work experience.
This is a specific design issue of the process. It depends on the input materials and the actual situation on site and cannot be generalized. . .
I would like to ask experts, when using MDEA for desulfurization simulation, AMSIM is selected as the model. Why are the results viewed in AMSIM different from the results output after running from PROii? Also, if the raw materials contain C3, what impact will C4 have? Thanks!
