Process And Plant For Producing One Or More Hydrocarbons

Abstract: A process (100-600) for producing one or more hydrocarbons is proposed, in which a first feed stream (A) is subjected to steam cracking (10) to obtain a first product stream (B), and a second feed stream (C) containing ethane is subjected to oxidative dehydrogenation (20) to obtain a second product stream (D), wherein at least a part of the first product stream (B) and at least a part of the second product stream (D) are used to form a demethanisation feed stream (E) which is subjected at least in part to demethanisation (16), and in which process at least partial oxygen removal (24) is carried out during the formation of the demethanisation feed stream (E). At least a part of the first product stream (B) is subjected to deethanisation (15) or depropanisation (19) separately from the second product stream (D) to obtain a lighter fraction (C2-, C3-) and a heavier fraction (C3+, C4+), the demethanisation feed stream (E) is formed by combining at least a part of the lighter fraction (C2-, C3-) and at least a part of the second product stream (D), and the oxygen removal (24) is carried out downstream of the combining. The present invention also relates to a corresponding plant.
