Abstract
Delayed petroleum coke is produced by conventional processing, including steaming of the coke in the drum to remove volatile material. After the steaming operation, the coke is quenched by injecting water onto the top of the steamed coke and passing the quench water downwardly through the coke, whereby the coke bed acts as a filter to trap fines which would pass overhead when the normal method of quenching by injecting quench water upwardly is used. Apparatus including retractable spray nozzles extending into the coke drum from the top is described.
