Abstract
The present invention provides a method of quenching heated coke in a coke drum. Quench water is fed into the coke drum to cool the coke, and the stress in the coke drum wall is monitored during the quenching. The rate of feeding the quench water into the coke drum is regulated to prevent the stress in the coke drum wall from exceeding a predetermined limit. The stress is monitored by measuring either the longitudinal thermal gradient or the rates of change in the drum wall temperature over time.
