摘　　要：为增产喷气燃料,中韩(武汉)石油化工有限公司采用中国石化石油化工科学研究院开发的拓宽馏程增产喷气燃料加氢精制(JeFIT)技术对2号煤油加氢装置进行改造。装置经过改造后一次开车成功,并进行了工业装置技术标定及长周期运转试验。标定结果显示,采用JeFIT技术可以加工终馏点为263℃的常一线油,得到的精制煤油色度(赛波特)为+30号、碱性氮质量分数小于1μg/g、热氧化安定性破点温度大于320℃、静态安定性氧化沉淀量小于4.6 mg/(100 mL),其他各项指标均满足3号喷气燃料质量要求。工业装置长周期运转情况表明,采用JeFIT技术可实现装置的安全平稳长周期运行和增产30%以上直馏喷气燃料的目标。In order to increase jet fuel production,the No.2 kerosene hydrogenation unit of SINOPEC-SK(Wuhan)Petrochemical Company Limited was revamped by using the jet fuel hydrofining technology(JeFIT)developed by the SINOPEC Research Institute of Petroleum Processing.After retrofitting,the unit was successfully started,and the technical calibration and long-term operation test of industrial unit were carried out.The results of calibration showed that the final distillation point was about 263℃,the color of the refined kerosene was+30,the basic nitrogen content was less than 1μg/g,thermal oxidation stability breaking point temperature was more than 320℃,static stability oxidation precipitation was less than 4.6 mg/(100 mL),and other indexes all met the quality requirements of China No.3 jet fuel.The long-term operation of the industrial plant showed that the application of JeFIT technology could realize the safe and stable long-term operation of the plant and the goal of increasing the production of jet fuel by more than 30%.
