Sensitivity analysis of the absorption tower
Thread Content
When simulating the absorption tower, sensitivity analysis is used to study the relationship between the operating pressure of the tower and a certain gas mass fraction at the outlet. The variable type is mass-frac, and it belongs to the exit gas stream. The operational variable ‘type’ is a module variable; ‘block’ refers to the tower module. The variable selected is STAGE-PRES ID1=1, yet the results of the calculations are all 0. I’m not sure why; please help analyze this. I just tried to analyze the relationship between the absorbent flow rate and the fraction of gas in the outlet gas, and the result was still 0 :Q :Q.

I’ve encountered a similar issue as well; it shows a message saying “THE VALUE IS MISSING”"
I encountered the same problem and don’t know how to solve it. How did you two manage to resolve it?
