结合R4 0 1热壁加氢精制反应器的开罐检验工作 ,针对加氢反应器长期运行后产生的影响安全性问题 ,提出了加氢反应器检验的有关方法和技术要求。通过对加氢反应器随机试块回火脆化量的测定 ,得到反应器运行 35 0 0 0h后仅有轻微的回火脆化量的结论 ,提出了加氢反应器安全运行的参考意见。 Combined with R4 0 1 hot-wall hydrotreating reactor canning inspection work, aiming at the safety problems caused by the long-term operation of the hydrogenation reactor, the relevant methods and technical requirements of the hydrogenation reactor test are put forward. Through the determination of the amount of temper embrittlement in the random block of hydrogenation reactor, the conclusion that there is only a slight amount of temper embrittlement after 3500h operation of the reactor is obtained, and the reference opinion for the safe operation of hydrogenation reactor is put forward.
