摘　　要：介绍了16万t/a煤焦油加氢装置升级改造为劣质柴油加氢改质装置的方案,分析了改造可能存在的技术及设备瓶颈,经改造增加循环氢脱硫系统、加氢进料泵、脱硫化氢汽提塔及柴油分馏塔底泵后,可年加工44万t劣质柴油。经技术经济评价分析,改造后总加工成本为532元/t柴油。In this paper,introduction is made to the proposal of upgrading from 160,000 t/a coal tar hydrogenation plant to inferior diesel hydrogenation plant.Bottlenecks possibly occurring in technique and in equipment during the modification are analyzed.The modification will have additional desulfurization system by circulating hydrogen,hydrogenation feed pump,H2S stripper and pump at bottom of diesel fractionating column,this upgraded plant will have capacity of refining 440,000 t inferior diesel per year.It’s reported in technical and economic evaluation that after the modification,the operating cost is totaled at￥532 Yuan for refining per ton of diesel.
