BOG再液化储罐火灾爆炸事故定量分析
Quantitative Analysis of Fire or Explosion Accident of BOG Re-liquefaction Storage Tank
摘要
Abstract
The BOG re-liquefaction process,which recycles boil-off gas(BOG)from LNG,can reduce natural gas loss and economic damage.However,the large quantities of LNG stored in tanks,once leaked,can mix with air to form an explosive mixture,making it highly susceptible to fire and explosion accidents when exposed to an ignition source.This study employs the Dow Chemical Fire and Explosion Hazard Index Method to quantitatively assess the risk of storage tank units in the BOG re-liquefaction process by determining parameters such as the Material Factor(MF),Process Unit Hazard Factor(F3),Fire and Explosion Hazard Index(F&EI),and Safety Compensation Factor.The results show that the storage tank unit has an F3 value of 6.93,an F&EI of 146,a hazard level of"Very High",an exposure radius of 37 meters,and an exposure area of 4 299 m2.When process control compensation measures,material isolation compensation measures,and fire prevention measures are implemented,the F&EI can be reduced to a minimum of 74,the hazard level drops to"lighter",and the exposure radius and area are reduced to 19 meters and 1 134 m2,respectively.These findings indicate that through targeted safety compensation measures,the risk and impact of fire and explosion accidents in the BOG re-liquefaction storage tank unit can be significantly mitigated.关键词
