【摘要】：中国石化上海高桥分公司3.0Mt/a柴油加氢装置为适应生产国Ⅴ排放标准柴油需要,结合公司加氢精制原料分配情况和柴油生产现状进行了装置改造。改造后,装置满负荷(285t/h)生产标定结果表明:以56.14%直馏柴油、35.09%焦化汽柴油及8.77%催化裂化柴油组成的混合原料,在体积空速1.05h~(-1)、高压分离器压力6.51 MPa、氢油体积比540、原反应器(R1101)入口温度315℃、R1101床层平均温度353℃、第二反应器(R1102)入口温度346℃、R1102床层平均温度348℃的操作条件下,精制柴油硫质量分数达到8μg/g以下,十六烷值提高7.7个单位,达到51.9,各项性能指标完全达到国Ⅴ排放标准。
[Abstract]:In order to meet the needs of producing country V emission standard diesel oil, the 3.0Mt/a diesel hydrogenation unit of Sinopec Shanghai Gaoqiao Branch was revamped according to the distribution of hydrorefined raw materials and the present situation of diesel oil production. After revamping, the calibration results of full load (285t/h) production show that the mixed feedstock composed of 56.14% straight-run diesel oil, 35.09% coking gasoline diesel and 8.77% catalytic cracking diesel oil, the volume space velocity is 1.05h ~ (- 1), the pressure of high pressure separator is 6.51 MPa, hydrogen / oil volume ratio 540, the inlet temperature of the original reactor (R1101) is 315 鈩，
