摘要
国内某炼化企业利用加氢裂化装置产品质量好、生产方案灵活的特点,开展了最大化生产非柴油产品、降低柴油收率的工业实践。结果表明:在尚未全面实施压减柴油策略的情况下,该装置平均每年可加工124.2 kt催化裂化柴油和120.4 kt直馏柴油;实施压减柴油策略后,增产轻石脑油方案的轻石脑油收率可达46.29%,增产重石脑油方案的重石脑油收率可达53.41%,增产喷气燃料方案的喷气燃料收率可达46.01%。此外,通过挖掘潜力,装置可生产5号工业白油特种油。在不改变该加氢裂化装置原设计及催化剂级配体系的条件下,通过调整原料配比及性质、优化生产方案等方式,该装置压减柴油能力可达到400 kt/a。
A domestic refinery took advantage of the good quality and flexible production plan of hydrocracking unit to produce non-diesel products and reduce the diesel yield.The results showed that the unit could process 124.2 kt of FCC diesel and 120.4 kt of straight-run diesel on average every year without implementing the strategy of reducing diesel,the yields of light naphtha,heavy naphtha and jet fuel could reach 46.29%,53.41%and 46.01%,respectively.In addition,the unit could produce special oil such as No.5 industrial white oil by tapping its potential.Without changing the original design of the hydrocracking unit and the catalyst grading system,the capacity of reducing diesel production could reach 400 kt a by adjusting the feedstock ratio and properties and optimizing the production scheme.
