Process And System For Producing One Or More Hydrocarbons

Abstract: The invention relates to a process (100, 200) for producing one or more hydrocarbons in which a first feedstock stream (A) is subjected to steam cracking (10) to obtain a first product stream (B), and an ethane-containing second feedstock stream (C) is subjected to oxidative dehydrogenation (20) to obtain a second product stream (D), wherein at least some of the first product stream (B) is subjected to processing (12) which comprises selective hydrogenation (125) of hydrocarbons having two carbon atoms and demethanisation (126) to obtain hydrocarbon fractions (C2H4, C2H6), wherein at least some of the second product stream (D) is subjected to trace removal (24) which comprises the removal of oxygen and/or acetylene to obtain a subsequent stream (E), and wherein at least some of the subsequent stream (E) is fed to the processing (12) at a position downstream of the selective hydrogenation (125) and upstream of the demethanisation (126).At least some of the subsequent stream (E) is subjected to the removal (25) of carbon dioxide upstream of the feed-in point to the processing (12). The present invention also relates to a corresponding system.
