FIELD: machine building.
SUBSTANCE: procedure for treatment of flow of natural gas contained in raw stock flow (10) consists in at least two stages: (a) raw stock flow (10) passing through rectification column (12), and production of flow of gas (20) and flow of liquid C2 + (30); (b) compression at least part of gas flow (20) at passing through one or more compressors of supply for production of compressed flow (40); and (c) simultaneous actuation of at least one of supplying compressors with one or more separate compressors of cooling agent used in one or more separate circuits of cooling agent circulation by means of mechanical connection of said compressors.
EFFECT: reduced capital and operational expenditures in liquefaction installation.
