轻烃回收装置大检修动火风险管控措施探讨

针对轻烃回收装置火灾爆炸事故大部分发生在维检修阶段的现象,通过结合生产实际,提出采用动火前施工工序确认制度,严控高风险点位,避免"立体交叉"动火作业等措施,杜绝经验主义和侥幸心理,最大限度避免动火作业着火爆炸事故的发生。文章介绍了轻烃回收装置的介质特点及主要工艺,分析了轻烃回收装置大检修基本流程及动火风险,提出控制动火施工安全风险的管理实践。

Discussion on Risk Management and Control Measures for Construction Fire of Light Hydrocarbon Recovery Unit during Major Repair

Aiming at the fact that most fire and explosion accidents of light hydrocarbon recovery units occurred in the maintenance and repair stage,by combining with the production practice,it is proposed to adopt the construction procedure confirmation system before starting fire,strictly control of the high risk position,and avoid the "three-dimensional cross" fire operation,put an end to empiricism and fluky psychology,so as to avoid fire explosion accidents in the fire operations to the greatest extent.This paper introduced the medium characteristics and main processes of light hydrocarbon recovery unit,analyzed the basic flow of overhaul and fire risk,and proposed the practice management for the control of construction fire safety risk.
