焦炉煤气的爆炸危险分级分组

Classification of Explosion Risk of Coke Oven Gas

焦炉煤气是煤化工行业经常碰到的一种爆炸危险介质,它是煤焦化后的产物,可以作为原料生产甲醇、LNG(液化甲烷)等化工产品。实际工程项目中焦炉煤气的MESG值(最大试验安全间隙)很多已达到IIC级别。论文通过工程实例,探讨焦炉煤气的级别设定,以供参考。

Coke oven gas is an explosive dangerous medium often encountered in coal chemical industry, It is the product of coal coking, and can be used as raw material to produce methanol, LNG （liquefied methane） and other chemical products. In actual engineering projects, the MESG value of coke oven gas （the maximum test safety clearance） has reached IIC level This paper discusses the level setting of coke oven gas through engineering examples, for reference.
