With the development of the LNG industry, LNG storage has become increasingly large-scale and atmospheric pressure. The domestic design and manufacturing have reached 50,000 m3, and a single atmospheric pressure storage tank with 250,000 m3 and 160,000 m3LNG has been established in the coastal area. At present, the LNG storage tanks designed, manufactured and installed in China are mainly 5000m3 and 10000m3, which are widely used in LNG liquefacturing plants or LNG peaking stations. The amount of LNG produced by industrial exhaust gas is generally relatively small, and LNG storage tanks of about 1000m3 are commonly used.
