What are the storage methods of LNG cryogenic storage tanks( 3) - Doer equipment


The third is the structure of LNG low-temperature and atmospheric pressure tank, including bimetallic tank, and the outer tank adopts prestressed concrete structure; There are aboveground tanks and underground tanks, 50000m ³ The following are mostly bimetallic cans.


The inner and outer tanks of atmospheric tank are installed and manufactured on site, and the production cycle is long.


The operating pressure of LNG cryogenic storage tank is 15kpa and the operating temperature is - 162 ℃. It is a flat bottom double wall cylindrical tank. The tank body is composed of inner and outer layers, and the two layers are thermal insulation structure and cold insulation layer. The inner tank is used to store liquefied natural gas, while the shell is used to protect and keep cold. In order to reduce the transfer of external heat into the tank, the designed inner and outer tanks are separated and independent. The tank item is a self-supporting vault. The inner tank item must have sufficient strength and stability to withstand the external pressure caused by cold insulation materials and the internal pressure generated by internal gas.
