摘　　要：结合LNG接收站工程设计实践,介绍了LNG接收站的工程组成和工艺流程,并对LNG接收站进行了危险辨识及风险分析。基于LNG的低温、易挥发、易扩散和易燃的特性,介绍了LNG接收站的预防泄漏、平面布置、超压保护、紧急停车、泄漏控制与探测、火灾探测与保护系统的设计原则及方法,根据蒸气云爆炸超压的后果计算,对接收站内建筑物的抗爆设计提出了要求。Consistent with current engineering design practice of the LNG receiving terminal,this paper introduced the compositions and the process flow of the LNG receiving terminal,identified potential hazards and conducted risk analysis. Based on LNG ＇s cryogenic,volatile,easy to spread and flammable characteristics,the design principles and the following safety measures of the LNG receiving terminal were explained,such as leakage prevention,layout design,overpressure protection,emergency shutdown,leakage control and detection,fire detection and protection system. According to the calculations of vapor cloud explosion overpressure,recommendations of explosion resistance of the building inside the LNG receiving terminal were proposed.
