I hope u all are doing fine. This is my first time to any forum.
I have simulated my refinery column (an orthodox one) in Hysys by characterizing crude and specifying operating parameter like P,T, flow,etc. Our column overhead contains kero minus fraction and one gas oil side stripper, operating with top and middle pump arounds.
for preheat we have cold and hot preheat train which utilizes hot streams from pump arounds and bottom products of other towers.
I have simulated in a relatively simple manner, like using one heater instead of multiple exchangers as preheat train.
Adding preheat exchangers are driving me nuts and i find my self completely paralyzed to do so. I also had a look to solved example in hysys which proves that preheat train could be efficiently added to tower simulation. but my question is how.???
any help in this regard would be highly appreciated and will be proven motivation to continue with forums.
