Hi all
Struggling to find anything on this in my vast library of paperwork or indeed on the net.
Fired furnace upstream of crude unit , power failure scenario, furnace goes offline .
Overhead vapour line from furnace still feeds into column. What % if any of the residual heat in the furnace should be applied to the remaining liquids in the furnace to continue vaporisation , and , for how long.
Found one reference that says 40% of design and for 1 hr ...seems high to me , any thoughts from experienced members please?
thanks
