As Cracking takes place in the Drum, Gas Oil and Lighter Components are generated as a Vapor Phase and separate from the Liquid and Solids.

The Drum Effluent is Vapor (except for any Liquid or Solids Entrainment) and is directed to Main Fractionator.

The solid Coke, formed in the On-Stream Coke Drum as the Cracking Reactions continue to completion, is deposited and remains in the Coke Drum in a porous structure that allows flow through the Pores. Depending upon the overall Coke Drum Cycle being used, a Coke Drum may fill in 16 to 24 hours.

After the Drum is full of the solidified Coke, the Hot Mixture from the Furnace is switched to the Second Drum. While the Second Drum is filling, the Full Drum is steamed out to reduce the Hydrocarbon content of the Petroleum Coke, and then quenched with Water to cool it. The Top and Bottom Heads of the Full Coke Drum are removed, and the Petroleum Coke is then cut from the Coke Drum with a high pressure Water nozzle, where it falls into a Pit, Pad, or Sluiceway for Reclamation to Storage.
