Hello* Experts!
I need help and time of yours.

Actually* I am working as a trainee engineer at Refinery* and I have assigned for the simulation of the refinery-wide model (except HDU and reformer at this stage).

I have simulated my model up to the good extent. and will also provide the file if someone shows interest in helping me.

some exchangers are showing temperature crossover* though I can't find any as per my knowledge.
another is a Pump-Around issue.

w8ing for replies to get the ball rolling.
