    The invention relates to refrigeration. The purpose of the invention is to reduce energy consumption and simplify the technological scheme. The mixture containing carbon dioxide is cooled and partially condensed in cooler 2, from which, as a mixture, gas-liquid enters separator 3 where it is separated. From the separator, gas and liquid are separated in separate streams into distillation column 6. Using heater 7, some of the liquid in the lower part of the column is evaporated, gas rises through the column, enriched with light hydrocarbons and removed as a product. Condensate for irrigation columns are cooled to m-ry -30 ... +30 C and served from its bottom. From the middle part of the column below the level of the gas and liquid inlet, the gaseous side fraction is withdrawn and condensed under pressure. 3 з, п, ф-л, 1 Il. to CO

    j The invention relates to a refrigeration engineering, in particular to a technique for separating mixtures of hydrocarbons by the method of cooling and rectification,
    The purpose of the invention is to reduce energy consumption and simplify the technological scheme.
    The drawing shows an installation diagram which allows to realize the proposed method of separation of the mixture,
    The installation contains a mixture supply pipeline 1, a cooler 2, a separator 3 connected by pipelines 4 and 5, delivering gas and liquid to the rectification column 6, a heater 7 is installed in the lower part of the column 6,: Pipe 6 and 8 are installed on the column 6 pipeline
    Part of the liquid from fraction C. from the lower part of the column through line 11 through cooler 12 is fed to the irrigation of column 6 and flows down the plates, washing the fraction into the lower part of the column. From the middle part of the column below the liquid and gas injection level, the product Cj + as side fraction is withdrawn through line 9. Part C of the C fraction from the bottom part of the column is withdrawn as product by line 16.
