Abstract: The invention relates to a process for the production of ethylene by oxidative dehydrogenation (ODH) of ethane, comprising: a) supplying ethane and oxygen to a first ODH zone which is formed by multiple reactor tubes containing a mixed metal oxide ODH catalyst bed; b) contacting the ethane and oxygen with the catalyst resulting in multiple effluent streams, wherein the multiple reactor tubes are cooled by a coolant; c) mixing at least a portion of the multiple effluent streams from step b) resulting in a mixture comprising ethylene, unconverted ethane and unconverted oxygen; d) supplying at least a portion of the mixture from step c) to a second ODH zone containing a mixed metal oxide ODH catalyst bed; e) contacting at least a portion of the mixture from step c) with the catalyst in the second ODH zone resulting in a stream comprising ethylene and unconverted ethane.

Abstract: The invention relates to a process for the production of ethylene in an integrated configuration comprising (i) a steam cracker configuration which comprises a steam cracker unit, a water condensation unit and a carbon dioxide removal unit and (ii) an oxidative dehydrogenation (ODH) configuration which comprises an ODH unit and a water condensation unit, wherein an effluent coming from the ODH configuration, which effluent comprises unconverted ethane and ethylene, is fed to the steam cracker configuration at a position which is downstream of the steam cracker unit, and wherein unconverted oxygen, carbon monoxide and acetylene are removed from at least a portion of the stream coming from the ODH unit by oxidation of carbon monoxide and acetylene into carbon dioxide in an oxidation unit which is located at a position (a) which is downstream of the ODH unit, and (b) which is downstream of the steam cracker unit and upstream of the carbon dioxide removal unit of the steam cracker configuration.

Abstract: The invention relates to a process for the production of ethylene by oxidative dehydrogenation of ethane, comprising: a) subjecting a stream comprising ethane to oxidative dehydrogenation conditions, resulting in a stream comprising ethylene, unconverted ethane and light components; b) subjecting ethylene, unconverted ethane and light components from the stream resulting from step a) to distillation, resulting in a stream comprising ethylene and light components and a stream comprising unconverted ethane; c) optionally recycling unconverted ethane from the stream comprising unconverted ethane resulting from step b) to step a); and d) subjecting ethylene and light components from the stream comprising ethylene and light components resulting from step b) to distillation at a top column pressure which is higher than the top column pressure in step b), resulting in a stream comprising light components and a stream comprising ethylene.
