INSTALLATION FOR EXTRACTION OF ETHANE AND C HYDROCARBONS FROM NATURAL GAS Russian patent published in 2024 - IPC F25J3/02 

FIELD: gas industry.

SUBSTANCE: invention relates to equipment for processing natural gas and can be used in gas industry. Proposed plant comprises drying unit 1, heat exchangers 2-4, separators 5-8, demethanizer 9 with heater, deethanizer 10 with refrigerating machine 11, expanders 12 and 13, compressors 14 and 15, reducing devices 16-19. Bottom of demethanizer 9 is connected to deethanizer 10. Fourth separator 8 is connected to the demethanizer by the separation residue supply line and is equipped with a separation gas discharge line, which adjoins the dry stripped gas discharge line before the heat exchanger, on which after the said adjoining heat exchanger 4 is located, additional heat exchanger 3 connected to natural gas supply line before and after multi-flow heat exchanger 2, and compressor 15. Expanders 12 and 13 are connected to compressor 14 and compressor of refrigerating machine 11.

EFFECT: reduced power consumption and reduced ethane losses.
