| 摘 要： | 强化传热是炼化企业实现绿色低碳发展和提升综合竞争力的有效途径。本文基于丰富的工程知识沉淀与炼化设计实践，通过系统梳理、总结，将炼化企业的强化传热工程策略划分为设备元件、工艺过程和全厂3个层次。通过梳理管壳式换热器等的工程应用方案，归纳了面向特殊工艺和介质的设备元件强化传热；通过总结芳烃、原油蒸馏、乙烯等装置热能/冷能利用，归纳了面向工艺与工程技术集成的工艺过程强化传热；通过总结全厂大系统回收与优化利用低温热资源、蒸汽系统梯级优化利用、循环水系统串级利用等，归纳了炼化企业全厂强化传热。强化传热工程策略在海南炼化公司、青岛炼化公司的实际应用表明，两者的综合能耗、单因能耗均达到国内先进水平。本文的阐述有望为强化传热工程策略的发展、完善，为丰富炼化工程强化传热内涵发挥积极的指导和示范作用。

| Abstract: | Heat transfer enhancement is an effective way to achieve low-carbon development and enhance competitiveness of refinery and petrochemical enterprises. Based on the rich engineering knowledge and refining design experience, the engineering heat transfer enhancement strategy is divided into three steps by systematical classification: equipment, process and whole plant. The equipment enhancement strategy for special processes is recommended by combining application of shell-and-tube heat exchangers. The process enhancement strategy is generalized by analysis of the thermal/cold energy utilization in process of aromatics, crude oil distillation, ethylene, etc. The whole plant enhancement strategy includes the use of low-temperature heat resources, stair-step utilization of steam system and cascade utilization of recycled water systems. These strategies were successfully applied to Hainan and Qingdao Refinery and helped to reduce the energy consumption. It is expected from the study in this paper to strengthen the development of the heat transfer engineering strategy and enrich connotation of the heat transfer enhancement in petrochemical process. |
