火灾环境液化石油气卧罐稳定性与静态可靠性分析
Stability and static reliability of horizontal LPG tank exposed to fire
摘要
Abstract
The liquefied hydrocarbon pressure vessel exposed to heat radiation from fire is extremely dangerous which may incur the boiling liquid expanding vapor explosion (BLEVE) of disaster domino effect.In this paper,the stability and static reliability of a horizontal LPG tank exposed to fire were studied.A two-node lumped temperature model (LTM) was proposed by considering LPG thermodynamic properties and pressure relief process of the safety valve.The LTM was validated using the experimental results of U.S.Army Ballistic Research Laboratory (BRL).According to the heat balance,a stable state of the LTM was derived,which showed that the dry wall and LPG temperature and the safety valve action could together determine whether the BLEVE would occur.Following the stability analysis,a limit state equation (LSE) was derived.The static reliability of the tank was obtained by applying the first-order reliability method (FORM) and response surface method (RSM) to LSE.The proposed analysis method of stability and static reliability is helpful to both quantitative risk assessment (QRA) of domino effect and inherently safer design (ISD) of pressure equipment.关键词
