Errors in board efficiency and product purity resulting from sensitivity analysis
Thread Content
** ERROR WHILE CHECKING INPUT SPECIFICATIONS FOR VARIED VARIABLE IN SENSITIVITY BLOCK: “S-3” – NO “STAGE-EFF” SENTENCE WAS ENTERED IN THE REFERENCED PARAGRAPH. VARIABLE DEFINITION IGNORED. Please take a look at this error and let me know if I missed setting something (Note: I have set the Murphree plate efficiency for the entire tower in Block-efficiencies) I earnestly request answers from fellow sea lovers; thank you very much!
Why isn’t anyone answering? Everyone, please help take a look. Thank you!
Personally, I think the poster might not have set the board efficiency correctly in the sensitivity analysis; it differs from the board efficiency specified earlier in the module, which is causing the error shown above. It is recommended that the poster share what they have done so it can be taken a look at.
I’m also quite interested in this issue; the original poster can share the BKP so we can take a look
Personally, I think that the variable that changes during sensitivity analysis isn’t defined in the model
In my simulation, the error is the same as yours; what I analyzed was the change in recovery rate with respect to the temperature at the bottom of the tower. The independent variable seems to have to be an operational parameter such as the reflux ratio. Looking forward to experts explaining it.
Without the simulation files, it’s difficult to determine where the error lies
Literally, does that mean the control variable for S-3 is undefined?
