摘　　要：中石油克拉玛依石化有限责任公司汽油池中催化重整汽油和加氢汽油占比相近,且高辛烷值、低芳烃、低烯烃汽油调合组分比例较低,导致芳烃和烯烃含量无法满足国Ⅵ汽油质量标准要求。鉴于上述瓶颈,制定汽油质量升级和成品油结构优化方案,2018年大修期间对催化裂化、催化裂化汽油加氢脱硫、柴油加氢改质和连续催化重整装置进行改扩建,新建轻汽油异构化和醚化装置。方案实施后,汽油池中芳烃体积分数下降5.0百分点,烯烃体积分数下降2.2百分点,调合汽油产品满足国Ⅵ质量标准,柴汽比灵活可控,预计2019年柴汽比为1.25,企业年度经济效益增加2.6538亿元。In the gasoline pool of PetroChina Karamay Petrochemical Co.Ltd.,the proportion of catalytic reformer gasoline and hydrogenated FCC gasoline was similar,and the blending proportion of high-octane,low-aromatic and low-olefin gasoline was relatively low,resulting in that the aromatics and olefin contents could not meet the requirements of China Ⅵ standards.To solve the above bottlenecks,a plan for upgrading the gasoline product and optimizing the structure of gasoline pool was presented.During the overhaul in 2018,the catalytic cracking unit,FCC gasoline HDS unit,diesel hydroupgrading unit and continuous reformer were revamped and expanded,and a light gasoline isomerization and an etherification unit were newly built.After the implementation of the plan,the volune fractions of aromatics and olefin in the gasoline pool decreased by 5.0 and 2.2 percentage points,respectively.The gasoline product met the China Ⅵ.The ratio of diesel to gasoline was flexible and controllable.It is estimated that the annual economic benefit will increase by 265.38 million Yuan in 2019,with a diesel gasoline ratio of 1.25.
