How liquid nitrogen is saved in tanks?
Nitrogen is available in liquid form after compression. If it is exposed to atmosphere directly or comes in contact with heat it would flash (evaporate).
So we need to protect the nitrogen storage from the outside temperature. The boiling point of nitrogen is ‑195.8oC. To achieve that it is stored in an inside vessel with an outer vessel surrounding it.
The annular space between the two vessels is evacuated to ensure the outside temperature won’t enter inside as no medium is there. This method is similar to what we see in a thermos flask
