Coke drum design Refining, Gas and Petrochemical

Theory behind coke drum failure is discussed, with detailed solutions centred on drum design and support structures as previously discussed. Thus, few refinery owners have the option of increasing cycle time, as they must balance drum distortion with the desire to meet rising throughput requirements. usually 40–50ft above the cone
