One of the common problems in the application of cryogenic storage tank
Generally, low temperature and normal pressure storage tanks are used in liquefaction plant and receiving terminal station, which is Doer to the large volume of LNG storage tanks in receiving terminal station (single tank volume is more than 50000 m) ³）， Other types of tanks can not do this. The liquid received is transported by LNG tank ship. The tanks on LNG tank ship are also in the form of low temperature and normal pressure, and the pressure changes little. In addition, bog condensing device is installed in the receiving terminal station, which can convert bog into LNG again.
Because there are liquefaction methods in the liquefaction plant, the bog produced during storage can be converted into regeneration gas for liquefaction, so the low temperature atmospheric pressure storage tank is used, and the evaporation of bog has little effect on it.
Since the LNG used in the station is transported by truck tanker, the LNG in the tanker is under pressure, and a large amount of gasification and bog gas will be produced when it is discharged into the low temperature atmospheric pressure tank. Because bog is a normal pressure gas, the investment and operation cost of bog compressor are high. The operating cost of LNG pump also increased.
