摘 要 在能源消费加剧与炼油产业规模不断扩大的同时，原油短缺、加 工原油劣质化、环境污染等问题已日益凸现，因此炼油工艺和生产过 程的节能降耗工作必须引起高度重视。 本文首先综述了石油化工过程用能分析方法，介绍了用能分析三 环节理论模型。在此基础上，采用三环节理论模型对中石化洛阳分公 4 司220×10t/a 蜡油加氢处理装置的用能过程进行了简要分析。介绍 4 了220×10t/a 蜡油加氢处理装置的工艺原理、工艺技术和工艺流程， 重点对比分析了该装置的用能现状及与同行先进装置的差距。在此基 4 础上，提出了220×10t/a 蜡油加氢处理装置能耗方面存在的问题， 制订了切实可行的优化方案，并对优化后的节能效果及各项技术经济 指标作了分析。通过优化改造，装置能耗得到明显降低，每年可产生 经济效益约1852 万元。 关键词：用能分析三环节模型、蜡油加氢处理装置、能耗、优化 ABSTRACT With the energy consumption increased and the refining industry expanded, some problems such as the shortage and poor quality of crude oil the environmental pollution, have become more and more serious. More attention should be paid to the work of energy-saving and consumption reducing for the refining process production process. First of all, the analysis method of energy utilization was comprehensively described for petrochemical process and the 3-links theoretical pattern of energy utilization analysis was introduced. Then, the 4 energy utilization process was analyzed for the 220×10 t/a wax oil hydrogenation unit in SINOPEC Luoyang Branch by adopting the 3-links theoretical pattern. And the process principle, process technology and 4 process flow of 220×10 t/a wax oil hydrogenation unit were introduced. The current situation of energy consumption of the unit was analyzed carefully and it was compared with the similar unit in petrochemical field . The problems existed in energy consumption of the unit was discovered and a corresponding practical optimization scheme was worked out. Meanwhile, the energy-saving effects and each
