国产热壁加氢反应器失效与保障

Failure and Safeguard of Hot-wall Hydroprocessing Reactors

随着国产热壁加氢反应器的数量不断增加和服役时间的延长,连多硫酸腐蚀、堆焊层氢致剥离、母材回火脆化、氢脆、表面开裂等时效损伤出现的情况越来越多.文章对这些导致反应器失效的问题作了概要分析和讨论,着重从生产管理上对国产热壁加氢反应器的保障技术进行了探讨.

With increasing number of hot-wall hydroprocessing reactors and extension of service time, the occurrence of polythionic acid corrosion, hydrogen induced spalling of weld overlay, temper embrittlement of base metal, hydrogen embrittlement and surface cracking etc. was increased. Various factors leading to the reactor failure were analyzed and discussed and safeguard of hot-wall hydroprocessing reactor was explored in respect of production management.
