Coke drums are primary equipment associated with the processing of oil sand bitumen. Damage of coke drums, in the form of bulging deformation or cracking have been reported from time to time. Every year, millions of dollars are spent on repairs and even more (~ $2 million per day) are lost due to interruption of production. Our recently completed work has identified the leading mechanisms to initiation and propagation of damage. The work has also shown a number of further improvement opportunities in the fundamental design methodology of coke drums, including material selection, evaluation of stress/strain history, assessment of thermal-mechanical fatigue lives and operational procedures. In this proposed project we will focus on the development of a more accurate life prediction and reliable design methodology for coke drums. A corresponding design software tool will also be developed for designers, processing and maintenance engineers in the user sectors. The above targets will be reached through well planned and tightly-coupled research activities including acquiring field measurement data, laboratory experiments, numerical simulation and theoretical modeling. Five high quality personnel will be trained through participation in this research project. A more accurate understanding of damage mechanisms and the new design principles will result in constructing more robust new coke drums and in improving management of existing coke drums. As an end-product of the research project, the developed design and analysis software will make our research contributions more easily shared by coke drum fabrication and user communities. It will have commercial application within a high-demand market. Large investments in oil sands continue to occur in Western Canada. The contributions from this proposed research will not only benefit the industrial partners involved, but also extend to a large portion of the Canadian oil industry. It will increase the competence of Canadian companies in the world market, improve the profitability of the Canadian industry, free up labor demands and advance knowledge of the technology.

可乐鼓是与油砂沥青加工相关的主要设备。焦炭鼓的损坏，以凸起的变形或破裂形式不时报道。每年，数百万美元用于维修工作，由于生产中断而损失了更多（每天约200万美元）。我们最近完成的工作已经确定了引发和传播损害的主要机制。这项工作还显示了可乐鼓的基本设计方法中的许多进一步改进机会，包括材料选择，压力/应变历史的评估，热机械疲劳生活和操作程序的评估。在这个拟议的项目中，我们将重点关注更准确的寿命预测和可乐鼓的可靠设计方法。还将为用户行业的设计人员，处理和维护工程师开发相应的设计软件工具。上述目标将通过良好的计划和紧密耦合的研究活动来达到，包括获取现场测量数据，实验室实验，数值模拟和理论建模。通过参加该研究项目，将对五名高质量的人员进行培训。对损坏机制和新设计原则的更准确了解将导致建造更强大的新可乐鼓以及改善现有可乐桶的管理。作为研究项目的最终产品，开发的设计和分析软件将使我们的研究贡献更容易被可乐鼓制造和用户社区共享。它将在高需求市场中提供商业应用。在加拿大西部，对油砂的大量投资继续进行。这项拟议的研究的贡献不仅将使所涉及的工业合作伙伴受益，而且还可以扩展到加拿大石油行业的很大一部分。它将提高加拿大公司在世界市场上的能力，提高加拿大行业的盈利能力，释放劳动力需求并提高对技术的了解。
