摘　　要：中国石油独山子石化分公司炼油一部原油蒸馏装置目前主要加工管输哈萨克斯坦原油、克拉玛依玛湖原油和南疆牙哈原油,该装置设计混合柴油收率为31%。近些年市场对柴油需求日渐减少,为了缓解柴油库存压力,缓解因原油加工量低、乙烯装置直供石脑油量不足的情况,通过实施常压蒸馏装置及减压蒸馏装置侧线流程调整,优化常压蒸馏塔操作,从而降低直馏柴油收率至26.06%,优化了公司产品分布,对提高公司整体运行效益做出了突出贡献。At present,PetroChina Dushanzi Petrochemical Company mainly processes Kazakhstan crude oil,Karamay Mahu crude oil and South Xinjiang Yaha crude oil,and the designed yield of mixed diesel is 31%.In recent years,the demand for diesel in the market has been decreasing.In order to alleviate the high pressure on the refinery’s diesel inventory and the shortage of naphtha directly supplying ethylene unit due to the less volume of the crude oil than before.Some outstanding contributions were made to improving the refinery overall operating efficiency by implementing the adjustment side line pumparound of atmospheric and vacuum distillation units,optimizing the operation of atmospheric distillation tower,which could lead to reducing the yield of straight-run diesel to 26.06%and optimizing the refinery’s product distribution and improving the refinery’s overall operating efficiency.
