Beschreibung
Zusammenfassung:	The invention relates to a storage-tank gas-phase communication method and mainly solves the problems of breather loss as well as gas-phase burning explosion risk and low oil-gas recovery efficiency in the prior art. The storage-tank gas-phase communication method includes that gas-phase spaces of storage tanks are connected through a gas-phase communication device, the gas-phase communication device comprises gas-phase communication pipelines (1), an oil-gas adsorption and desorption tank (2), an oil-gas recovery pipeline (3), an oil-gas recovery device (4), a control valve (5), emergency cut-off valves (7), flame arresters (8) and at least one storage tank (9), one emergency cut-off valve (7) and one flame arrester (8) are arranged on each gas-phase communication pipeline (1) led out from the gas-phase space of each storage tank, and the oil-gas recovery pipeline (3) is arranged on the oil-gas adsorption and desorption tank (2) and connected with the oil-gas recovery device (4). The problems are well solved, and the method can be applied to gas-phase communication of the storage tanks.
