摘　　要：火炬是石化厂处理全厂排放可燃气体的重要的安全环保设施。整个火炬系统本身的安全可靠是全厂各装置安全可靠运行和满足环保要求的重要保证。目前,火炬系统设计中使用了许多自动控制,自控仪表的失灵会给全厂带来安全隐患。火炬系统"本质安全"设计理念是解决全厂火炬排放气诸多不确定因素的重要保证。对石化厂火炬系统中主要的三大系统"本质安全"设计提出了应采取的设计方法,对今后同类设计具有借鉴和指导意义。Flare is important safety and environmental protection facility to deal with the discharged combustible gases in petrochemical plant. A safe and reliable flare system is important guarantee for the safe and reliable operation of plant-wide devices and meeting the environmental requirements. Currently,plenty of automatic control is applied in the design of flare system. So the failure of automatic instruments will bring safety hazard for the whole plant. The design philosophy of intrinsic safety for flare system is essential for solving the uncertainties in flare gas emissions of the whole plant. This paper presents the corresponding design methods for the intrinsic safety of the three main systems in the flare system of petrochemical plant,which provides reference and guidance for similar design in the future.
