LNG sub tank


LNG sub master tank refers to the tank in which multiple sub tanks containing LNG are connected in parallel and placed in the master tank filled with thermal insulation materials in a certain arrangement. It is usually built to meet the storage of large volume and pressure, in medium and large (1000M ³~ 10000m ³ Storage scale) LNG gasification station is widely used in the field.


Product structure: LNG sub tank and mother tank are composed of multiple sub tanks, one mother tank, corresponding process pipelines, valves, instruments, etc.


Sub tank: as the main container containing low-temperature medium, it is made of austenitic stainless steel s30408; The sub tank is a vertical cylindrical leg structure. According to the volume, 4, 7 or 10 sub tanks are arranged in a certain way to connect the gas and liquid phases of all or grouped sub tanks through pipelines.


Mother tank: as the protective shell of thermal insulation system, Q345R / 16MnDR material is usually used. The mother tank contains all the sub tanks, and uses powder stacking insulation for cold insulation to ensure that the storage medium is gasified as little as possible.


Main technical parameters


Storage medium: LNG


Working pressure: 0.2MPa ~ 1.6Mpa


Single volume: 600m ³~ 3000m ³


Equipment type: storage tank, pressure vessel


Main advantages


The single storage capacity of the equipment is large, which has the advantages of small land occupation, less investment and simple operation compared with the vacuum tank with the same volume.


The equipment maintains the operating pressure through the self supercharger without booster pump, bog compressor and other equipment, with low operation cost and simple maintenance.
