4×5000m³lng storage tank
with the development of lng industry, lng storage is becoming more and more large and atmospheric, and the domestic design and manufacturing has reached 50000 m ³， in the coastal area, a single station with a capacity of 250000 m has been built ³、 160000 m ³ lng atmospheric storage tank is used to receive lng on board.
at present, the lng tanks designed, manufactured and installed in china are mainly 5000m long ³ and 10000m ³， it is widely used in lng liquefaction plants or lng peak shaving stations. the amount of lng produced by industrial tail gas is generally small, and 1000m is commonly used ³ lng storage tanks on the left and right.
