摘　　要：为克服传统危险源及可操作性分析(HAZOP)的主观性,提高LNG加气站风险管理水平,提出HAZOP定量分析方法。该方法以传统的HAZOP分析方法为基础,结合道化学火灾、爆炸指数评价法(F&EI)和事故树分析(FTA),运用风险矩阵,使HAZOP分析能进行定量评价。根据LNG加气站工艺流程,将LNG加气站划分为11个节点,以LNG储罐"压力过高"偏差为例,通过量化的HAZOP分析得到其危险等级,并提出了有针对性的建议措施。结果表明,定量HAZOP分析可以有效地识别LNG加气站风险,可作为LNG加气站风险管理的工具之一。The quantitative analysis method of hazard and operability is proposed in order to overcome the subjectivity of tradition hazard and operability analysis method and improve the risk management level of LNG station. The method is based on tradition hazard and operability analysis method, and it makes the hazard and operability analysis quantitative by combining chemical fire and explosion hazard index method with fault tree analysis and using risk matrix. A LNG station is divided into 11 nodes according to the work process of LNG station. The dangerous level of the LNG station is got by using ＂high pressure＂ of LNG storage tank as deviation and quantitative analysis of hazard and operability, and the corresponding prevention measures are proposed. The application results show that the quantitative analysis method of hazard and operability can effectively identify the risk of LNG station and can be used as a tool for the risk management of LNG station.
