Dear Potential Client,
I have read the attached documents and fully understand your requirement. I am skilful in Aspen and has no problem to simulate it. In order to run the study, I will create the sensitivity case in the simulation with 10 deg C temperature difference and analyse the calculated duty.
PFD can be generated directly from simulation, if prefer the cad file i can do it as well.
I am committed to give the best solution to your assignment.
Please free to massage me should you need further discussion.
Regards
Malek
