FIELD: oil producing industry.
SUBSTANCE: invention relates to cleaning of vapor-gas medium discharged into atmosphere from hydrocarbons. Proposed method includes delivery of liquid medium by pump into liquid-gas jet device, evacuation of container and/or reservoir and compression of liquid medium in liquid-gas jet device by energy of liquid medium, delivery of mixture of gas-gas and liquid media formed in liquid-gas jet device into separator, separation of mixture into gaseous phase and liquid medium in separator with removal of gaseous phase and liquid medium from separator. Gaseous phase from separator is delivered into absorber to which hydrocarbon liquid is fed as absorbent. Hydrocarbons from gaseous phase are absorbed by hydrocarbon liquid in absorber, and gaseous phase cleaned from hydrocarbons and hydrocarbon liquid with dissolved hydrocarbons of gaseous are let out from absorber. Hydrocarbon liquid with dissolved hydrocarbons of gaseous phase are delivered from absorber into desorber. Two design versions of plant for implementing the method are described.
EFFECT: reduced losses of oil, improved efficiency of oil cleaning from vapors of gas-gas forming in storage or filling of reservoirs.
