摘　　要：以绥中SZ36-1减一线馏分油为原料,在柴油加氢中型试验装置进行生产变压器基础油的可行性验证,结果表明柴油加氢装置具备生产变压器油基础油的可能性;在中海油气(泰州)石化有限公司柴油加氢装置进行工业试生产,在不改变工艺流程的情况下,当新鲜进料量为25 t/h、产物循环量为15 t/h、体积空速为0.96 h^(-1)、反应压力为7.0 MPa、反应器入口温度为345℃、氢油体积比为600时,能够生产满足变压器油质量标准(GB 2536—2011)中基本物化性质要求的变压器油基础油。对工业装置工艺参数核算结果显示,该柴油加氢工业装置可在设备改动不大的情况下用于生产变压器油基础油。Using the first vacuum side stream of SZ36-1 as raw material,the feasibility of producing transformer oil base oil was verified in a pilot plant industrial trial production at the diesel hydrogenation unit of CNOOC Taizhou Petrochemical Co.,Ltd.without changing the process flow.When the fresh feed rate was 25 t/h,the product circulation rate was 15 t/h,the volume space velocity was 0.96 h^(-1),the reaction pressure was 7.0 MPa,the inlet temperature of the reactor was 345℃,and the volume ratio of hydrogen to oil was 600,the product transformer oil basic oil could meet the general physical and chemical properties requirements of transformer oil quality index(GB 2536—2011).The calculation results of the process parameters of the industrial unit show that the diesel hydrogenation unit can be used to produce transformer oil base oil with little modification of equipment.
