METHOD OF CLEANING VAPOR-AND-GAS MEDIUM FORMED DURING STORAGE OF OIL OR GASOLINE OR AT FILLING RESERVOIR WITH OIL OR GASOLINE FROM HYDROCARBONS AND PLANT FOR REALIZATION OF THIS METHOD (VERSIONS)

摘要

FIELD: fluidics.;SUBSTANCE: proposed method includes delivery of liquid medium to liquid-and-gas jet apparatus by means of pump and discharge of vapor-and-gas medium from reservoir being filled with oil or gasoline with the aid of the same pump followed by compression in liquid-and-gas jet apparatus due to energy of liquid medium; mixture of vapor-and-gas and liquid media is delivered from liquid-and-gas jet apparatus to separator where it is separated into gaseous phase and liquid medium; gaseous phase is fed from separator to absorber where hydrocarbons are absorbed from gaseous phase by hydrocarbon liquid and gaseous phase cleaned from hydrocarbons is discharged from absorber. Hydrocarbon liquid containing dissolved hydrocarbons is directed from absorber to first desorber where hydrocarbons dissolved in it are separated due to building-up pressure below pressure in absorber, thus partially cleaned hydrocarbon liquid is obtained. Part of this liquid is directed to second desorber where pressure is below that in first desorber and hydrocarbons dissolved in partially cleaned liquid are separated. Hydrocarbons thus separated are discharged by means of second liquid-and-gas apparatus to whose inlet partially cleaned hydrocarbon liquid from first desorber is fed by means of second pump. Hydrocarbon liquid formed in second desorber is fed as absorbent to absorber and mixture of partially cleaned hydrocarbon liquid and gaseous hydrocarbons separated in second desorber formed in second liquid-and-gas jet apparatus is fed to first desorber. Two versions of realization of this method are described in Specification.;EFFECT: reduced losses of oil or gasoline; enhanced efficiency of cleaning.;10 cl, 1 dwg
