Sensitivity analysis problem! !

A simulation calculation of an absorption tower was carried out using the RadFrac module of Aspen Plus 11.1; a chemical reaction and electrolyte package (Elec Wizard) was added, and the simulation ran successfully. However, when performing the sensitivity analysis, I set one of the component flow rates at the gas phase outlet to vary with the number of trays, and the result was that the flow rate was 0 for all values of the number of trays. Why is this? I wonder what God missed? Please offer some advice!

I’m not sure if your absorption is related to a reaction; if it’s absorption as part of a reaction, it doesn’t seem quite appropriate

Changing the number of plates does not guarantee that all variables remain unchanged; for example, the residence time
