摘　　要：针对以中国石化塔河炼化有限责任公司现有原料组分油难以调合得到满足国ⅥB标准98号车用汽油的问题,采用控制重整油分馏塔进料油组分性质、调整临氢异构化两套装置生产操作条件等方法,得到性质优化的汽油调合原料油组分;进而,设计了以优化后的重整汽油馏分(抽取二甲苯)、异构化汽油馏分与C_(9)^(+)重芳烃组分、外购异辛烷、MTBE等为调合原料的98号车用汽油调合方案,并通过试验调合得到了满足GB 17930—2016标准要求的98号车用汽油(ⅥB)。该方案以优化后装置组分油为调合原料,无需装置改造、降低外购异辛烷调合比例,提高了企业经济效益,为企业产品结构优化提供了技术支持。In response to the difficulties in blending the existing feedstock oils of SINOPEC Tahe Petrochemical Co.,Ltd.to meet the ChinaⅥB standard No.98 gasoline for motor vehicle,by controlling the feedstock properties of reformate in fractionating column of reformate and adjusting the operating conditions of two units of hydroisomerization,the blending feedstock of gasoline with optimized properties was obtained.The blending scheme of No.98 gasoline for motor vehicles(ChinaⅥB)was designed by using optimized reformer gasoline fraction(extracting xylene),isomerized gasoline fraction and C_(9)^(+)heavy aromatic component,purchased isoctane and MTBE as blending raw materials.In this scheme,the component of the optimized unit was used as the blending raw material,without need of the reconstruction of the unit,and the blending proportion of purchased isooctane was reduced,it improved the economic benefits of enterprises and provided technical support for the optimization of product structure of the enterprise.
