Operation Analysis of 2.4 Mt/a Hydrocracking Unit

介绍了中国石化九江石化公司2.4 Mt/a加氢裂化装置的主要技术特点和催化剂装填情况,结合第一周期生产运行期间的主要操作参数、原料油及产品性质、物料平衡及装置能耗等情况,对装置运行情况进行考察。结果显示,加氢精制催化剂FF-56和加氢裂化催化剂FC-50活性及稳定性较好,产品均满足生产要求。装置工艺流程技术先进,可以通过调整反应温度灵活地调整产品质量,装置能耗优于设计值。同时对第一周期出现的轻石脑油纯度较低和原料油过滤器反冲洗频繁等问题进行分析并及时解决。

The technical features and catalyst loading condition of 2.4 Mt/a hydrocracking unit in Sinopec Jiujiang company were introduced. Based on main operating parameters, feedstock and product properties, material balance and energy consumption in the first cycle, the operating condition of the unit was investigated. The calibration results showed that the activity and stability of the hydrotreating catalyst FF-56 and hydrocracking catalyst FC-50 were good and products met the production requirements. The unit is advanced in process technologies. The product quality can be flexibly adjusted by adjusting the reaction temperature, the energy consumption is better than the design value. At the same time, the problems in the first cycle were analyzed and resolved.
