what are the storage methods of lng cryogenic storage tanks（ 1) (2) - doer equipment
at present, lng low-temperature storage tanks commonly used at home and abroad include atmospheric storage, sub parent tank under pressure storage and vacuum tank under pressure storage. the storage method mainly depends on the storage capacity.
the second is the vacuum tank:
the vacuum tank is a double-layer metal tank, the inner tank is a low-temperature resistant stainless steel pressure vessel, the outer tank is made of carbon steel, the interlayer is filled with thermal insulation material and vacuumized. the vacuum tank is manufactured in the factory and transported to the site as a whole after pressure test.
the total storage capacity of lng storage tank is 1000m ³ below, multiple vacuum tanks are generally used for centralized storage. at present, the maximum volume of a single vacuum tank used in china is 150m ³。 the process flow of vacuum tank is relatively simple. generally, the supercharger is used to pressurize the tank, and the materials flow into the gasifier by pressure. there is no power equipment and low energy consumption. therefore, all small lng gasification stations at home and abroad basically adopt the form of vacuum tank.
