FIELD: oil industry.
SUBSTANCE: invention relates to cleaning of vapor-gas medium in storage or at filling of reservoirs from hydrocarbons. Method includes delivery of liquid medium by pump into liquid-gas apparatus, pumping out by said apparatus vapor-gas liquid medium from reservoir under filling and/or storage reservoir, and compression of medium in liquid-gas jet apparatus owing to energy of liquid medium, delivery of mixture of vapor-gas and liquid media formed in liquids-gas jet apparatus into separator and separation of mixture inn separator with letting it out of separator. Gaseous phase is directed from separator into absorption tower whereto hydrocarbon liquid is fed to use as absorbent. Oil from storage reservoir or from transfer pipeline is fed to separator or to pump input and simultaneously liquid medium is let out into oil storage reservoir or into reservoir to be filled with oil. Degassed oil from degasser is delivered into absorption tower for use as hydrocarbon liquid. Degassed oil is formed in degasser by separating light hydrocarbons from oil under vacuum. Two design versions of plant for implementing the method are provided.
EFFECT: reduced losses of oil, improved efficiency of oil cleaning from vapors of vapor-gas medium formed at storing or filling of reservoirs.
