Absorber tower simulation problem in Aspen

Now that I know the composition, temperature, and pressure of the materials entering and leaving the absorption tower, I want to determine the diameter and height of the tower (including the packing). I’m looking for the specific steps to do this; the absorption tower does not have a condenser or a reheater. The main issue is that it’s difficult to determine the number of tower plates
The number of theoretical plates is determined based on the minimum theoretical plate count from the simulation; by then taking into account the equivalent plate height of the packing, the actual number of theoretical plates can be calculated. Once the number of plates is known, the tower height can be determined as well. The calculation of the tower diameter requires knowledge of data such as the gas and liquid loads inside the tower, density, surface tension, as well as the flooding ratio, in order to determine the tower diameter. You’d better find a book and look up the calculation for the tower diameter by yourself.
