在浙江石油化工有限公司350万t/a柴油加氢裂化装置上,以直馏柴油、催化柴油、浆态床柴油、重芳烃混合油为原料,考察了掺炼重芳烃对工艺参数及产品质量的影响。结果表明:掺炼重芳烃后,混合原料油中多环芳烃含量升高,反应氢耗增大,1段加氢反应器(R-1001)精制床层温升明显增加;当重芳烃掺炼比例(占原料油质量分数)为5.0%时,R-1001裂化床层温度与氢耗波动大,反应转化率为91.0%,产品重石脑油芳构指数升高了5.39个百分点。
- Abstract:
-
The effects of blending heavy aromatics on process parameters and product quality were investigated with the mixed oil of straight run diesel, catalytic diesel, slurry bed diesel and heavy aromatics as raw materials in the 3.5×106 t/a diesel hydrocracking unit of Zhejiang Petroleum & Chemical Co Ltd. The results showed that after blending the heavy aromatics, the content of polycyclic aromatic hydrocarbons in the mixed raw oil and the reaction hydrogen consumption were increased, and the temperature rise of the refining bed of the 1-stage hydrogenation reactor(R-1001) increased significantly. When the blending ratio of heavy aromatics (mass fraction of raw oil) was 5.0%, the R-1001 cracking bed temperature and hydrogen consumption fluctuated greatly, and the reaction conversion rate was 91.0%, and the aromatization index of the product heavy naphtha increased by 5.39 percentage points.
