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