乙醛装置亚燃烧反应现象剖析及处理

Analysis and treatment of sub-combustion reaction in acetaldehyde unit

分析了乙烯氧化反应系统亚燃烧产生的原因,总结出"先窒息后恢复"的处理方法,即避免了停车,又能保障装置安全、高效运行。

The mechanism of the sub-combustion reaction in an ethylene oxidation system was analyzed, and an effective handling method, i.e.＂initially cut off and then resume＂ was summarized. It can be efficiently avoided that the reaction system interlock shutdown, and the device have been operating safely.
