I understand your theory but I am 99% sure the strippers are not a problem. I understand strippers can remove the light ends form the front of the distillation, however they are there to control the flash by removing a very small amount of material which may change the 5% point or less as you...
Stripping steam in the side strippers is typically at a minimum to push flash spec, trying to maximize kero and diesel yield. I have push stripping steams in the past with out seeing any change.
I'm not quite sure what you are getting at with the side strippers. Are you thinking stripping...
EmmanuelTop,
The problem exists in both CDU's, it always has. I'm 100% sure its a design issue. The question is how to improve it.
The side strippers are fine. The only temps on the tower are draw temps. The temperature profile responds to changes in P/A as they should. For instance...
Hi,
I recently started a new job at an oil refinery and quickly noticed that the 90%-10% overlap between kero to diesel and diesel to gas oil are 100 deg F and 150 deg F respectively. My background is mostly in FCC's not crude stills but I am used to overlap in main Frac's being more in the...
