The inlet flow rates of gas and liquid to the absorption tower were halved, but the results were different – why is that?
Thread Content
I used the AMSIM module to simulate an absorption tower. I have now reduced both the gas flow rate and the liquid flow rate by half; logically, the composition of the gas at the outlet should remain unchanged, and the results should be the same. However, this is not the case in reality. Does anyone know why?
AMSIM is a non-equilibrium simulation; of course, the flow rate is halved when the tower diameter remains unchanged.
How can one determine what the tower diameter set by the software is in the current simulation?
By specifying the type of packing inside the tower – whether it’s random packing, structured packing, or plate packing – once the type is chosen, simply run the simulation. The results can be found in the report; generally, they are provided after the hydraulic data related to the tower, and it is said that the results can be obtained by multiplying by a certain coefficient
