Can an explosion occur when an air vent on a oil tank draws in air?

This shouldn’t happen, after all, nitrogen is introduced into the top of the tank, and nitrogen provides protection; moreover, the inhalation of air is brief, and once pressure builds up, the nitrogen will displace it
Generally not; the storage tank is equipped with an electrostatic grounding system, and there is also a nitrogen seal. The time during which air can enter is brief, as the nitrogen will displace that air.

Our tank’s breather valve allows only exhaust and no intake; a water seal tank has been installed, along with two nitrogen supply lines

A flame arrester is added behind the breather valve.
No, at least not to date, there have been no reports of static electricity explosions occurring due to air being drawn in through the breather valves on oil tanks.

Of course, there is a possibility that the internal floating roof could be damaged, leading to oil and gas vaporization. But as mentioned earlier, nitrogen is usually used to maintain pressure and prevent the tank from collapsing. If the nitrogen fails and air gets in, the amount of air that enters is limited. If oil and gas do vaporize, it will be above the explosion limit, or if very little vaporizes, it will be below the lower limit. Additionally, static electricity on the storage tank is also strictly controlled through grounding
