After a large amount of air enters the storage tank, it mixes with the oil gas, possibly forming explosive gas. In order to prevent the storage tank from generating fire and explosion, a nitrogen sealing system is arranged on the storage tank in some enterprises, nitrogen is supplemented when the pressure of the storage tank is reduced, the micro-positive pressure of the storage tank is maintained, and air is prevented from entering to form an explosive gas environment. After the storage tank is nitrogen-sealed, a large amount of nitrogen gas needs to be consumed, and the operation cost of the tank field can be increased. In addition, after the nitrogen seal is arranged, the waste gas discharged by the storage tank contains a large amount of nitrogen, so that the treatment difficulty of subsequent facilities is increased.
