the storage time of liquid nitrogen in liquid nitrogen tank

On the storage time of liquid nitrogen in liquid nitrogen tank, this should be the most important problem for people who use liquid nitrogen tanks to store liquid nitrogen, because some people don't know the storage time of liquid nitrogen tanks so that irreparable losses occur.

 
This has a lot to do with the thermal insulation of your liquid nitrogen storage tank, because every day there will be liquid nitrogen gasification, which will be discharged through the safety valve. Of course, if you use gas, it will not be discharged. The daily gasification capacity of Dewar tank is about 4%, and that of pangchao tank is about 1-2%. In addition, depending on the evaporation rate of your tank, the liquid nitrogen will be gasified slowly during the storage process. When the amount you use is lower than the gasification amount, the tank pressure will increase slowly. When it rises to the set bearing pressure of the tank, the safety valve will automatically jump and discharge.
So these are the factors that affect the storage time of liquid nitrogen. Therefore, the storage time of liquid nitrogen in liquid nitrogen tank is an approximate number, which is difficult to make a specific answer.
