大型重整反应器内件修复的难点及对策

The Difficulties and Countermeasures of Internal Parts Repair in Large Reforming Reactor

以某炼油厂连续重整装置中内件严重损坏的一台大型重整反应器为例,针对外筛网筒上下部分的损坏、中心筒的损坏,以实际工作条件提出了修复方案。通过对修复部位难点与质量要点的分析,实施过程中采取了相关的对策和控制措施,保证了修复工作顺利的完成,满足了设备的工艺性能,证实了修复技术的可行性与有效性。

A large reforming reactor with severely damaged internals in a continuous reforming unit of a refinery is taken as an example,in view of the damage of the upper and lower parts of the outer screen cylinder and the damage of the central cylinder,the repair scheme is put forward according to the actual working conditions.Through the analysis of the difficulties and the quality of the main points of the repaired parts,the relevant countermeasures and control measures are taken in the process of implementation,that ensures the smooth completion of the repair work,meets the process performance of the equipment,confirms the feasibility and effectiveness of the repair technology.
