The Aspen simulation for CO2 absorption towers involves only one tower – how can different tower diameters be designed?
Thread Content
I’ve seen that in many designs for simulating CO2 absorption towers, there is only one tower considered, but the diameters of the upper and lower sections of this tower differ in reality. How can such a scenario be simulated? Seeking advice from experts! Benfieldfa can also absorb CO2; when simulating an absorption tower with Aspen, can the chemical absorption take place first in the reactor before proceeding to the absorption tower?
I see. It should be to consider the simulated gas-liquid phase loads; using the inlet of the semi-depleted liquid as a boundary, the tower is divided into upper and lower sections with different diameters, and then the tower diameter is calculated using formulas based on the gas velocity
The RadFrac column internals module divides the column into various sections; in the size mode, different column loads are assigned to each section, and the diameter of each section can be determined using Aspen calculations
