摘　　要：中国石化洛阳分公司常减压蒸馏装置常压塔改造后一次轻油收率有所提高,生产调整上以效益为导向,围绕增加喷气燃料的产量开展优化工作。利用PETRO-SIM流程模拟软件建立装置模型,对常一线油进行离线操作优化。模拟结果表明,常压塔塔顶石脑油终馏点对常一线油的产量和性质影响较大,实际操作中通过常压塔塔底注汽、常二线汽提蒸汽、常二线油流量和常压塔塔顶石脑油终馏点的调节,实现了增产常一线油的优化目标。同时在优化过程中,发现常压塔高温位热源利用率低、喷气燃料加氢装置喷气燃料分馏塔石脑油组分少的问题,提出了解决措施。After revamping the atmospheric column of atmospheric and vacuum distillation unit in SINOPEC Luoyang Company,the light oil yield increased.The production adjustment is guided by benefit,and the optimization work is carried out around increasing the output of jet fuel.A model of off-line operation optimization was established to optimize the first side line oil with PETRO-SIM.The results of simulation showed that the end point of overhead naphtha had a greater impact on the output and properties of the first side line oil.The optimizing target of increasing the output of the first side line oil was realized by adjusting the flow rates of stripping steam into bottom of atmospheric tower and the second side line stripper,the flow rate of the second sideline oil,as well as the end point of naphtha at the atmospheric tower top.During the optimization,the problems of low utilization of high temperature potential heat source in atmospheric pressure tower and lack of naphtha in jet fuel fractionator in jet fuel hydrogenation unit were found,and the solutions were put forward.
