FIELD: technological processes.
SUBSTANCE: invention relates to equipment for separation of gaseous mixtures. Described is an apparatus for extracting hydrocarbons from a gas mixture, comprising a recuperative heat exchanger and a fractionating column arranged on the crude gas line, as well as a cooling machine and reducing devices, in which fractioning column is equipped with upper and lower heat-mass-exchange sections in reinforcing part and heater in stripping part, which is located on bypass line of recuperative heat exchanger, bottom of the column is equipped with a hydrocarbon fraction output line C1+, on which a reducing device and a recuperative heat exchanger are successively located, and the top of the column is equipped with a discharge line of the mixture of non-condensed gases, on which the reducing device is successively located, the upper heat-mass exchange section and the recuperative heat exchanger, wherein the lower heat-mass-exchange section is connected to the refrigerating machine by cooling agent inlet / outlet lines.
EFFECT: simplified installation and increased output of commercial gas.
