| The development of Liquefied natural gas (LNG) industry and technology has been a major breakthrough in the field of utilization of energy resources in the world. LNG safety, environmental protection, easy storage and transportation advantages, showed a significant growth trend in recent years and at the same time greatly facilitate LNG station building.However, LNG has the potential danger of leaks, fires and explosions, accidents can cause great losses to persons and property, accidents occur in LNG station and therefore LNG station for evaluation and control of risks, Risk reduction may have a larger social significance of the accident.This article from LNG Property, equipment and facilities, the environment and human factors LNG Station identification of the various risk factors.Establishment of LNG station fault tree of major equipment systems, and based on its probability analysis. Through LNG stations in all kinds of accidents established event tree analysis system mode, and summarize the LNGspill, fire, thermal radiation, and blast model. LNG station typical accident:blast of fire, vapour cloud explosion and BLEVE damage model in analysis.Select LNG field station typical case, application flammable, and easy burst, and toxic major dangerous source assessment method on plus gas station for integrated risk assessment, judgment plus gas station of risk grade is three level, plus gas station of control degree grade is clevel, learned that the plus gas station of major dangerous source himself by reached has by controlled standard, description the plus gas station within of security prevention, and Basic safety and quality meet the requirements, are basically in a security control of the stations.Finally for LNG stations put forward the corresponding countermeasures of risk control.This paper was completed LNG Risk assessment, risk control measures is proposed to control LNG Stations providing decision-making risk, developing risk management measures to improve LNG Station operation and management of security, facilitate the protection of urban safety, promoting national economic and social development. |
