摘　　要：富氧氧化工艺可以在不扩大设备设施规模的基础上,提高装置产能,但也会增大反应体系的火灾爆炸危险性和工艺操作难度。文章通过计算甲苯富氧氧化体系气相组成分析了其潜在的火灾爆炸危险性,并从甲苯—氧气—氮气混合气体爆炸三元组分图、甲苯氧化体系爆炸压力等方面分析了甲苯富氧氧化体系火灾爆炸危险性的增大;提出了针对富氧氧化体系必须加强进料氧含量控制、尾氧含量控制等安全控制措施,以保障装置安全运行。Enriched oxygen oxidation technology can improve the output without enlarging the equipment scale. But it also can increase the fire and explosion hazards and operation difficulty. This article analyzed the fire and explo- sion hazards of toluene-enriched oxygen oxidation system. And hazards were analyzed from toluene-oxygen-nitrogen flammable diagram and its explosion overpressure. At last, some safety countermeasures like feed oxygen limit and exhaust oxygen limit were offered to ensure its safety operation.
