摘要: 在石油炼制过程中,加氢技术已经成为提高石化产品质量的重要手段。加氢装置需要的氢气大部分由制氢转化装置提供。生产过程中,制氢转化炉的运行负荷会根据加氢装置处理量的变化情况进行调整。制氢转化炉负荷的变化会造成炉子内部温度分布变化,而炉内温度的变化又会直接影响炉管的运行寿命。文章依据制氢转化炉的结构、运行参数,建立有限元计算模型,模拟计算转化炉在不同负荷条件下内部温度场的分布特点,分析转化炉在不同负荷条件下内部各部位温度的变化情况,为炉管寿命的评价提供温度参数,同时为不同负荷下转化炉的操作提供指导。

Abstract: In the process of petroleum refining, hydrogenation technology has become an important means to improve the quality of petrochemical products. Most of the hydrogen required by hydrogenation plants is provided by hydrogenation conversion plants. In the production process, the operating load of hydrogen production converter will be adjusted according to the change of the capacity of hydrogenation unit. The change of hydrogen production converter load will lead to the change of temperature distribution inside the converter, and the change of temperature inside the converter will affect the operating life of the furnace tube directly. On the basis of the structure of the hydrogen production converter, operating parameters, the finite element model is established to simulate and calculate the internal temperature distribution of the converter under different load conditions, analyze the internal temperature change of each part in the converter under different load conditions and provide temperature parameters for the evaluation on the service life of furnace tube. Meanwhile, finite element model can provide guidance for the operation of the converter under different loads.
