Abstract: Natural gas plays a key role in energy transition of China, and the consumption of natural gas increases rapidly with the promotion of clean energy and transition from coal to gas in some areas in our country. Facing the problem of insufficient self-produced LNG, construction of receiving stations in coastal areas has been in full swing in recent years to facilitate the import of LNG. As the main medium of LNG receiving stations, natural gas is extremely volatile and easy to form explosive gas cloud when leaking. In addition, leakage of low-temperature LNG may also cause frostbite hazard to operators. In order to further understand and predict the impacts of leakage accidents in LNG receiving stations, this paper takes one domestic LNG receiving station as an example and analyzes LNG leakage of different units and equipment under different conditions. On this basis, the paper presents suggestions on the construction of LNG receiving stations and the design of safety facilities.
