A method for producing hydrocarbons is proposed, in which a product stream containing hydrocarbons is produced from a methane-rich feed stream and from an oxygen-rich feed stream in a reaction unit which is configured for implementing a method for oxidative coupling of methane, the product stream or at least a stream formed therefrom being treated cryogenically in at least one separation unit using at least one liquid, methane-rich stream. It is provided that in the at least one separation unit (10) a recycle stream is formed from methane contained in product stream (c) and from methane contained in the at least one liquid, methane-rich stream (e, v), the recycle stream being fed to the reaction unit (1) as the methane-rich feed stream (a), and in that the liquid, methane-rich stream (e, v) is provided as makeup.
Method for producing hydrocarbons, in which a product stream (c) containing hydrocarbons is produced from a methane-rich feed stream (a) and from an oxygen-rich feed stream (b) in a reaction unit (1) which is configured for implementing a method for oxidative coupling of methane, the product stream (c) or at least a stream formed therefrom being treated cryogenically in at least one separation unit (10) using at least one liquid, methane-rich stream (e, v), characterised in that in the at least one separation unit (10) a recycle stream is formed from methane contained in product stream (c) and from methane contained in the at least one liquid, methane-rich stream (e, v), the recycle stream being fed to the reaction unit (1) as the methane-rich feed stream (a), and in that the liquid, methane-rich stream (e, v) is provided as makeup.
Method according to any of the preceding claims, wherein the cryogenic treatment comprises a cooling procedure in at least one heat exchanger (34) which is operated with the at least one methane-rich stream (e) as refrigerant.
Method according to any of the preceding claims, wherein the cryogenic treatment comprises a separation procedure in a cryogenic separation device (4, 13) in which the at least one methane-rich stream (e, v) is charged as reflux.
Apparatus (100) which has all means installed for implementing a method according to any of the preceding claims and which is configured for implementing a corresponding method.
