[0002] In the daily operation process of the oil depot, oil gas recovery is a crucial link. The oil depot stores a large amount of oil products, and a large amount of oil gas will be volatilized into the air during the loading, unloading and storage of oil products. These oil gases not only contain recyclable oil resources, but also cause serious resource waste if directly discharged into the atmosphere.

[0003] At the same time, the oil gas contains a variety of harmful substances, such as benzene, toluene and other volatile organic compounds, which will form photochemical smog and other pollutants when discharged into the air, causing serious damage to the atmospheric environment and endangering the ecological balance and human health. Moreover, oil gas is a flammable and explosive substance, which can easily cause explosion and fire accidents when it reaches a certain concentration in the air and meets a fire source, bringing huge safety hazards to the safety production of the oil depot.
