摘　　要：哈尔滨石化公司800 kt/a加氢裂化装置采用常压蜡油和催化柴油为原料,在正常生产中存在反应加热炉热负荷低,加热炉热效率低的问题。通过分析得出加氢反应为强放热反应,通过换热流程优化,充分利用反应产物与原料换热在满足反应初始温度的前提下,停运反应进料加热炉完全可行,既可以解决反应加热炉热效率低的问题,还可以达到降低装置能耗的目的。通过模拟软件对加氢裂化装置进行模拟,经过模拟软件可以看出停运反应加热炉后,通过调整反应器出口温度及优化换热后,完全可以满足精制反应器入口温度的要求。通过实施停运反应加热炉节能项目后,装置节约瓦斯1800 t/a,减少烟气排放3964 m^(3)/h,减少碳排放1086 t/a,装置优化后,节能减排效果显著。Because the 800 kt/a hydrocracking device of Harbin Petrochemical Company has used atmospheric wax oil and catalytic diesel as raw materials,there are problems with low heat load and low heat efficiency of heating furnace in normal production.By analyzing the above problems,it can be concluded that the hydrogenation reaction is a strong exothermic reaction.By optimizing the heat exchange process,if the heat exchange between the reaction products and raw materials is fully utilized to meet the initial temperature of the reaction,it is completely feasible to shut down the reaction of feed heating furnace,which can not only solve the problem of low heat efficiency in the reaction of heating furnace,but also achieve the goal of reducing the energy consumption of device.The hydrocracking device is simulated by simulation software.It can be seen that after the shutdown of the reaction heating furnace,the requirements for the inlet temperature of the refining reactor can be fully met after adjusting the outlet temperature of the reactor and optimizing heat exchange.After implementing the energy conservation project of shutting down the reaction heating furnace,the device saves 1800 t/a of gas and reduces flue gas emissions by 3964 m^(3)/h and carbon emissions by 1086 t/a.After optimizing the equipment,the energy conservation and emission reduction effects are significant.
