it's not usually required, but if it's economical it does quite a bit in lowering the risk of fire and keeping the product from oxidizing
Yes, liquid nitrogen can be used to cool air passed through a heat exchanger. It is however a once through system. You would need a tank to hold the liquid nitrogen, and have more delivered every so often. very expensive.
It will heat up and evaporate.

.1483 GALLONS PER POUND FOR LIQUID NITROGEN 2000LBS X .1483 GALLONS/POUND = 296 GALLONS OF LIQUID NITROGEN IN 1 TON
What is the minimum amount of PSI you can have in your oxygen tank before you need to exchange tanks
you do not want air enter into the naphtha tank and mix with naphtha vapour.
Blenketing is widely used in industries for protection and process safety. Oil is blanketed in the tank to avoid oxidation of the oil, which leads to earlier degradation (very important if the oil is used as a heating utility) of the utility. Nitrogen blanketing is usually triggered by the temperature, for most thermal oil starts to degrade at around 60 deg C.In the food industry, oil product is used also as a blanket to prevent spoilage and also as a blanket to prevent air infiltrating the tank. Also, positive pressure is kept to avoid any iinfiltration from the outside of the tank.
no. Compressed nitrogen need not be insulated. Liquid nitrogen is always insulated. Typically compressed nitrogen is stored at high pressure(over 1000 psi) and liquid nitrogen is kept at less than 100 psi.
with a nitrogen tank
A pressure regulator is required on a nitrogen tank.
You need to buy a separte attachment for the A-5 and you should check to see if it is able to support using nitrogen
So far I've heard of methanol, and sugar.
Your local welding supply store should have nitrogen tanks, or know who your local compressed gas supplier is. You will most likely need to pay a significant tank deposit, and purchase a gas regulator for the tank.
Yes, any nitrogen tank is refillable.
Although well insulated, the tank will gradually warm and as it does so the liquid Nitrogen will boil off (the gas is allowed to escape from the tank which is not sealed and pressurized). This happens gradually, so the liquid Nitrogen can be stored for as long as some remains in the tank (this will depend on the size of the tank (Dewer - see link below)).
