4×5000m³LNG storage tank
4×5000m³LNG storage tank
With the development of the LNG industry, LNG storage has become larger and more atmospheric. The domestic design and manufacture has reached 50,000 m³. A single atmospheric storage tank of 250,000 m³ and 160,000 m³ LNG has been established along the coast to receive ship-borne LNG. .
At present, LNG storage tanks designed, manufactured and installed in China are mainly 5000m³ and 10000m³, which are widely used in LNG liquefaction plants or LNG peak shaving stations. The amount of LNG produced by industrial tail gas is generally small, and LNG storage tanks of about 1000m³ are commonly used.
