Hi all,
Is it better to stop using the agitator when heating a reactor?
Thanks for your help on this one

If you would add more pertinent details to the description of the equipment/problem, I can elaborate. As it stands, we don't know very much about your RX. Is the RX contents pumped through the hot oil heat exchanger and then returned to the RX, or does it have hot oil circulating through the hot oil heat exchanger and then through a jacket on the RX?
Good luck,

Our reactor is a vertical one (capacity 180.000 pounds aprox), the product is pumped from the RX to the external heat exchanger, and back to the reactor. At the shell side of the external heat exchanger we have the hot oil that is constantly circulating at about 530F and 600gpm.
Hope this information helps some more.
Thanks again for your hellp

So, yes, the delta T across the fluid is low, but that means that it's all at the same temperature, which is usually the desire.
A classic example of non-uniform heating is a microwave oven, where you can get boiling on the surface and still have frozen food in the center. Not many processes are happy with that type of temperature distribution.

I think it may be quick to dismiss all situations as needing agitation throughout the heating process.
