摘　　要：文章通过资料审查,现场观察及测量等方法分析了低温甲醇净化装置发生泄漏爆燃的原因。结果表明,缠绕垫片选型过大,法兰连接螺栓选型错误及N1法兰错边的存在是造成事故的主要原因。并通过表面探伤,金相检验,排除新生缺陷及材质劣化的情况下提出了整改措施。In order to found the leak reason of the Low temperature methanol adsorber Deflagration, the files examination、field observation and measurement were adopted. Rseurts show that： spirotallic gasket selection is too large, flange connection bolt type errors and the existence of N1 flange misalignment, and are the main cause of the accident. And through the surface inspection, metallographic examination, ensure no new defects and new material degradation was generate, and then proposed measures.
