摘　　要：某公司300×10^(4) t/a渣油加氢脱硫装置I系列第5周期运行至第453 d时,上流式反应器(UFR)2床层上部出现热点TI1288,运行至第465 d时径向床层温度达到24.1℃。经过分析得出影响热点温度的主要因素是反应温度、催化柴油和掺渣比,分析了热点TI1288形成后对装置运行的负面影响。提出了应对热点的运行措施,实现装置稳定运行547 d。Hotspot TI1288 appeared in the upper part of upflow reactor(UFR)2 bed at 453 days of operation in the fifth cycle of 300×10^(4) t/a hydrodesulfurization unit I,and the radial bed temperature reached 24.1℃at 465 days of operation.After analysis,it was concluded that the main factors affecting the hotspot temperature were reaction temperature,catalytic diesel and slag ratio.The negative influence of hotspot TI1288 formation on the operation of the plant was analyzed.The operation measures to deal with hotspots were put forward to realize stable operation for 547 days.
