Abstract: A method for producing hydrocarbons includes subjecting a first feed stream to steam cracking to obtain a first product stream, and subjecting an ethane-containing second feed stream to oxidative dehydrogenation to obtain a second product stream. A portion of the first product stream is subjected to a deethanization or a depropanization separately from the second product to obtain a lighter fraction and a heavier fraction. A demethanization feed stream is formed by combining at least a portion of the lighter fraction and at least a portion of the second product stream and is subjected at least in part to demethanization. Partial oxygen removal is carried out during the formation of the demethanization feed stream. The oxygen removal is carried out downstream of the combining step.

Abstract: A method for producing one or more hydrocarbons, includes subjecting a first feed stream to a steam cracking to obtain a first product stream and subjecting a second feed stream containing ethane to an oxidative dehydrogenation to obtain a second product stream At least a portion of the first product stream is subjected to a treatment to obtain hydrocarbon fractions. The treatment includes a selective hydrogenation of hydrocarbons having two carbon atoms and a demethanization. At least a portion of the second product stream is subjected to a trace removal, which comprises the removal of oxygen and/or acetylene, to obtain an subsequent stream. At least a portion of the subsequent stream is fed to the treatment at a position downstream of the selective hydrogenation and upstream of the demethanization. A portion of the subsequent stream is subjected to a carbon dioxide removal upstream of the feed point into the treatment.
