摘要
利用英国KBC公司开发的NHTR-SIM和HCR-SIM流程模拟软件分别模拟优化了石脑油加氢装置和柴油加氢裂化装置的加工全流程,提出了将浆态床重石脑油由全部掺炼于350万t/a柴油加氢裂化装置改为全部掺炼于360万t/a石脑油加氢装置,再进入连续重整装置的加工优化方案。结果表明:在模拟石脑油加氢装置掺炼浆态床重石脑油时,产品精制重石脑油的含硫、氮量分别为0.37,0.42μg/g,均满足重整装置进料小于0.5μg/g的指标要求,该方案可行;优化实施后,虽然该方案仅协同运行半年多,共加工浆态床重石脑油20.47万t,促进柴油组分原料加工量提升了17.82万t,但为公司2022年度综合创效达7928.3万元。
The NHTR-SIM and HCR-SIM process simulation software developed by KBC company of UK were used to simulate and optimize the whole process of naphtha hydrogenation unit and diesel hydrocracking unit respectively.The processing optimization scheme of slurry bed heavy naphtha from all mixed in 3.5 Mt/a diesel hydrocracking unit to all mixed in 3.6 Mt/a naphtha hydrogenation unit,and then into the continuous reforming unit was proposed.The results showed that when the slurry bed heavy naphtha was blended in the simulated naphtha hydrogenation unit,the sulfur and nitrogen contents of the refined heavy naphtha were 0.37,0.42μg/g,respectively,which met the requirements of the reforming unit feed less than 0.5μg/g,and the scheme was feasible.After the optimization and implementation,although the scheme had only been operated collaboratively for more than half a year,a total of 204.7 kt of slurry bed heavy naphtha had been processed,and the amount of raw material processing of diesel components increased by 178.2 kt,it resulted in the company′s comprehensive benefit increment of 79.283 million yuan in 2022.
