FCC Fractionator Desuperheating Zone - LCO in Bottoms Product

FCC Fractionator Desuperheating Zone - LCO in Bottoms Product

FCC Fractionator Desuperheating Zone - LCO in Bottoms Product

(OP)
I´m working in a FCC fractionation unit revamp and the main problem is the amount of LCO in bottom slurry.
According to simulation the efficiency of this zone is very poor and would be responsible for this situation.
Currently the desuperheating zone has 6 rows of sheds and we believe that changing them by grid packing would increase efficiency and solve this particular problem.
Plant personnel is reluctant to this change even when they recognize there is no improvement after cleaning the internals (a recent gamma scan showed that they are blocked)
Can anyone share experiencies about similar problems & solutions? How good is grid packing performance regarding efficiency, operating issues (coking, etc)?

Thanks in advance

I suggest you get hold of Henry Z. Kister's Distillation-Operation- McGraw-Hill; it brings references against grid packing in this service. See table 20.8 under the title: Troublesome Packed Column Internals.
