FIELD: oil industry.
SUBSTANCE: invention relates to jet facilities. Proposed method of cleaning vapor-gas medium from hydrocarbons includes delivery of liquid medium into liquid-gas jet apparatus, pumping out by said apparatus vapor-gas medium from reservoir filled with oil product and/or reservoir for storing oil product, and compression of medium in liquid-gas jet apparatus owing to energy of liquid medium, delivery of mixture of vapor-gas medium and liquid medium formed in liquid-gas jet apparatus into separator, separation of mixture into gaseous phase and liquid medium with releasing of gaseous phase and liquid medium out of separator. Gaseous phase from separator is directed to absorber into which hydrocarbon liquid is fed for use as absorbent, and absorption of hydrocarbons from gaseous phase is carried out in absorber by hydrocarbon liquid, after which gaseous phase cleaned from hydrocarbons and hydrocarbon liquid dissolved hydrocarbons from gaseous phase are separately released from absorber. Gasoline is used as oil product and hydrocarbon liquid. Prior to delivering into absorber, gasoline is cooled to temperature within minus 20°C and minus 80°C, and mixture of vapor-gas and liquid media formed in liquid-gas jet apparatus is compressed of pressure in separator within 0.15 Mpa and 1.20 MPa and 1/20 MPa. Gasoline is fed to separator or to input of pump, and simultaneously liquid medium is let out of separator into gasoline storage reservoir or tank to be filled.
EFFECT: improved efficiency of cleaning of vapor-gas medium forming at storing of gasoline or filling of reservoir.
