Heat integration of oil refining processes is an effective instrument in the technological modernization of industrial facilities. A more rational use of the heat carried by internal process streams is of particular importance for such energy-intensive technologies of heavy oil residue cracking as delayed coking. In this work, we construct a model of the existing heat exchange network of a petcoke production unit and analyze it using pinch analysis. The conducted study revealed violations of the basic pinch principles committed when designing the existing network. An approach to enhancing the energy efficiency of the process was proposed, involving retrofitting of the existing equipment without expanding the heat exchange surface.

提高延迟焦化装置的热交换效率

炼油过程的热集成是工业设施技术现代化的有效工具。更合理地利用内部工艺流携带的热量对于延迟焦化等重油渣油裂解等能源密集型技术尤为重要。在这项工作中,我们构建了石油焦生产装置现有热交换网络的模型,并使用夹点分析对其进行分析。所进行的研究表明,在设计现有网络时违反了基本的捏合原则。提出了一种提高工艺能源效率的方法,包括在不扩大热交换表面的情况下改造现有设备。
