加氢裂化装置反应器压降是影响装置长周期运行的重要因素,通过计算反应器的压降,总结适合加氢裂化装置的压差预测公式,以准确预测反应器压差上涨趋势及装置运行周期。

For a hydrocracking unit,the deposition of metals and carbon on the catalyst will increase with the extending operation time,resulting in an increase in the pressure drop of the reactor bed.The pressure drop of the reactor is an important factor affecting the long-term operation of the unit.Through calculating the pressure drop of the reactor,a prediction formula of reactor differential pressure suitable for this unit is summarized to accurately predict the rising trend of reactor differential pressure and the operation cycle of the unit.
