进入21世纪以来,中国石化工程建设公司(SEI)先后规划并建设了海南、青岛和惠州等一批新建千万吨级炼油企业,规划并改造扩建了燕山、天津、高桥和福建等一批老的炼化企业。在这些企业的规划与建设过程中,SEI始终坚持技术先进、投资合理、资源节约、能耗节省和经济效益好的新世纪炼油企业建设原则。目前,一部分企业已经投产,还有一部分企业正在建设过程中。投产企业的运行均取得了很好的经济效益和社会效益。通过对典型炼油企业的全厂能耗和主要工艺装置能耗的研究对比,分析了节能技术应用情况和节能潜力,提出了进一步做好节能工作的主要措施。
Since entering the 21st century, SEI has successively planned and constructed a batch of new 10-million-ton oil refineries in Hainan, Qingdao and Huizhou, planned and transformed a batch of Yanshan, Tianjin, Takahashi and Fujian batches The old refinery business. In the planning and construction of these enterprises, SEI always adheres to the principle of building a new-century oil refinery with advanced technology, reasonable investment, resource saving, energy saving and good economic returns. At present, some enterprises have been put into production, and some enterprises are under construction. The operation of production enterprises have achieved good economic and social benefits. Through the research and comparison of the energy consumption of the whole plant and that of the main process plant in a typical refinery, the application of energy-saving technologies and energy-saving potential are analyzed, and the main measures for further energy-saving work are put forward.
