When converting a static simulation of a rectification column into a dynamic one in PetroSIM, we get the following error:
"The steady state pressure profile of these tray sections may not be consistent with the rating data used in dynamics mode."

 

Can you please advise on the meaning of this inconsistency, its possible causes, and what a sensible workflow can be to resolve it?

 

 

Thanks in advance

I have never used PetroSIM, but I do know that dynamic simulators use different calculation methods than steady state simulators. They must do this to improve the calculation speed. I read the message as a warning, not an error. To me, it means 'the steady state calculations are more rigorous but we try to get as close as possible in dynamics mode. Confirm the final answer in steady state mode if this really matters.' Just compare the results in both modes.
