Hi Guys,
I'm a beginner modeling crude oil column, so i need some help to connect the ovhd of my column with the first heat exchanger of preheat train. I read some forums about that but i couldn´t converge this ovhd but I think I'm wrong with my method.
Attach my file Hysys 7.3.
I hope that someone could help because I started to feel much interest in crude oil columns.
Thanks
