This proposal is for a two and half year research program focusing on damage analysis and long term reliability evaluation of delayed coke drums - primary equipment associated with the processing of oil sand bitumen. The service lives of current coke drums are limited due to severe thermal-mechanical load experienced. Through tightly-coupled experimental investigation, theoretical modeling and FEM numerical simulation, a thorough understanding of the initiation and propagation of damage in coke drums will be obtained. A more reliable life estimation methodology will be developed, as well as the proposal of enhancements to delay the damage and to prolong lives of coke drums.

本建议书是一项为期两年半的研究计划，重点是与油砂沥青加工相关的主要设备-延迟焦炭塔的损坏分析和长期可靠性评估。目前的焦炭塔的使用寿命是有限的，由于严重的热机械负荷经历。通过紧密耦合的实验研究、理论建模和有限元数值模拟，对焦炭塔损伤的产生和扩展有了深入的了解。将开发一种更可靠的寿命估算方法，以及改进的建议，以延迟损坏和延长焦炭塔的寿命。
