4×10000m³ LNG atmospheric storage tank
With the development of the LNG industry, LNG storage is becoming larger and operating at atmospheric pressure. Domestic design and manufacturing have reached 50,000m³, and single units of 250,000m³ and 160,000m³ LNG atmospheric storage tanks have been established along the coast to receive ship-borne LNG.
Currently, the LNG storage tanks designed, manufactured, and installed domestically are mainly 5,000m³ and 10,000m³, widely used in LNG liquefaction plants or LNG peak shaving stations. The amount of LNG produced from industrial waste gas is generally small, and 1,000m³ LNG storage tanks are commonly used.
