INSTALLATION OF LOW-TEMPERATURE SEPARATION WITH NTSD DEPHLEGMATION FOR PROCESSING NATURAL GAS WITH EXTRACTING HYDROCARBONS C (OPTIONS) Russian patent published in 2019 - IPC B01D3/00 

Abstract RU 2681897 C1

FIELD: technological processes.

SUBSTANCE: invention relates to low-temperature separation plants and can be used in gas industry for extraction of hydrocarbons C2+ from natural gas. Disclosed is an apparatus, in version 1 including a drying unit, an external cooling circuit in the evaporator, a compressor, a condenser and a reducing device, recuperative heat exchangers, reducing devices, including at least one expander, pump, weathering device, low-temperature separator, dephlegmator and demethanizer. Alternative 2 instead of equipment of external cooling circuit includes compressor, refrigerator and reducing device.

EFFECT: invention provides high output of hydrocarbons C2+.
