Process and Plant for Producing One or More Hydrocarbons

A system for producing one or more hydrocarbons, the system being configured to:

• subject a first feed stream to steam cracking to obtain a first product stream and a second feed stream containing ethane to oxidative dehydrogenation to obtain a second product stream;
• form a demethanization feed stream using at least a portion of the first product stream and using at least a portion of the second product stream and to subject this to demethanization at least in part;
• carry out at least a partial removal of oxygen during the formation of the demethanization feed stream;
• subject at least a portion of the first product stream to deethanization or depropanization separately from the second product stream to obtain a lighter fraction and a heavier fraction,
• form the demethanization feed stream by combining at least a portion of the lighter fraction and at least a portion of the second product stream;
• and
• carry out the oxygen removal downstream of the combining step,
• feed at least a portion of the first product stream to the combining step without prior acetylene hydrogenation or with only partial acetylene hydrogenation;
• and
• carry out the oxygen removal as comprising an acetylene removal.
