摘　　要：介绍了中国石油锦西石化公司100万t/a柴油加氢改质装置的运行、存在问题、技术改造和主要事故等事项。在没有大规模停车检修的情况下,装置的连续运行周期长达7年以上。经过将分馏塔气提介质由蒸汽替换为氢气、回收利用分馏塔顶低压瓦斯、优化脱硫化氢塔进料流程和停用分馏塔进料加热炉4项技术改造后,装置的综合能耗[m（标准油）/m（柴油）]降低为20-24 kg/t。The operation,problems,revamping and main accidents of 1 Mt/a diesel oil hydrofining unit in Jinxi Petrochemical Company were introduced.The continuous operating cycle lasted over 7 years without a complete overhaul.After the stripping medium of fractionating tower was changed from steam to hydrogen gas,the low pressure gas at the top of fractionating tower was recycled,the feeding flow path of hydrogen sulfide removal tower was optimized and the feed heating furnace in fractionating tower was disused,the unit comprehensive energy consumption decreased to 20-24kg/t.
