Experts, is nitrogen blanketing necessary for coal tar storage tanks? Why?
It’s not necessary; the nitrogen seal is used to prevent the medium from coming into contact with air
Coal tar storage tanks do not require a nitrogen seal; such a seal is used to prevent the material from oxidizing and changing color when in contact with air, and this is not necessary for coal tar. It can be filled into barrels using nitrogen pressure.
Due to environmental regulations, if the odor is strong and there are no means to control VOCs, nitrogen sealing is definitely necessary
