We are in the process of expanding our Coker. We are adding two more Coke drums and another Coking heater. We plan to decoke one heater while continuing to run with the other. Coke heater “A” will feed drums 1 and 2, while coke heater “B” will feed drums 3 and 4. Are there any other Cokers doing this? How do you put one Coke heater back on line after decoking while continuing to feed with the other heater?
