摘　　要：中国石油吉林石化公司炼油厂Ⅰ催化裂化装置设计规模为140×10~4 t/a,能耗状况落后于当前催化裂化工艺技术的整体水平,主要表现在余热锅炉热量回收受限、部分设备技术落后老旧损坏、烟机运行效率低等方面。2015年6月Ⅰ催化裂化装置进行了技术节能改造,改造后,装置能耗降低了5.484kg oe/t。通过对节能技术改造实际运行数据对比分析,表明先进的技术和设备以及优化流程在降低装置的能耗方面起到至关重要的作用。同时装置间的热量综合利用更有利于进一步降低炼化装置的能耗。The design scale of the catalytic cracking unit I of oil refinery is 140×10 4 t/a,and the energy consumption is lagging behind the overall level of the current FCC technology,mainly in the aspects of the limited heat recovery of the waste heat furnace.Some old equipments are lagging in technology and damaged,also because of low operating efficiency of the smoke machine.In June 2015,the energy saving transformation of FCCU was carried out.After retrofit,the energy consumption of the unit was reduced by 5.484 kg oe/t.The comparison and analysis of the actual operation data of the energy saving technology transformation shows that the advanced technology and equipment and the optimization process play an important role in reducing the energy consumption of the device.At the same time,the comprehensive utilization of heat among the units is more conducive to further reduce the energy consumption of the refining plant.
