Coke Drum Life Cycle Management

Presented By

Premkumar Chinnaraj - Wood


Coke drums are a key equipment item on the Delayed Coking Unit and require continuous attention and analysis throughout the equipment lifecycle to help maximize drum life. Wood’s extensive analysis has proven that a joint team effort by our Reliability, Process and Operations team can effectively optimize the thermal gradients in the coke drums during operation, thereby improving the mechanical reliability and fatigue life of the drum. Regular monitoring and inspection can help with early detection of cracks that can be repaired during maintenance while avoiding unplanned shutdowns. In this presentation, we will review the life cycle steps and highlight a case study where optimization of thermal gradient optimization was performed to help improve drum reliability and reduce fatigue on the drums.
