    Abstract: The invention relates to a process for oxidative dehydrogenation of ethane, comprising the steps of: (a) subjecting a stream comprising ethane to oxidative dehydrogenation conditions; (b) removing water from at least part of the effluent resulting from step (a); (c) optionally removing unconverted oxygen and/or carbon monoxide and/or ycetylene from at least part of the stream comprising ethylene, unconverted ethane, carbon dioxide, optionally unconverted oxygen, optionally carbon monoxide and optionally acetylene resulting from step (b); (d) removing ethylene from at least part of the stream comprising ethylene, unconverted ethane and carbon dioxide resulting from step (b) or (c) by a complexation separation method; (e) partially and selectively removing carbon dioxide from at least part of the stream comprising unconverted ethane and carbon dioxide resulting from step (d); (f) recycling at least part of the stream comprising unconverted ethane and carbon dioxide resulting from step (e) to step (a).

    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.

    Abstract: The invention relates to a Process for the production of ethylene oxide, comprising the steps of: (a) producing ethylene by subjecting a stream comprising ethane to oxidative dehydrogenation conditions, resulting in a stream comprising ethylene, ethane, water and acetic acid; (b) separating at least part of the stream resulting from step (a) into a stream comprising ethylene and ethane and a stream comprising water and acetic acid; (c) producing ethylene oxide by subjecting ethylene and ethane from the stream comprising ethylene and ethane resulting from step (b) to oxidation conditions, resulting in a stream comprising ethylene oxide, ethylene, ethane and water; (d) separating at least part of the stream resulting from step (c) into a stream comprising ethylene and ethane and a stream comprising ethylene oxide and water; (e) recycling ethylene and ethane from the stream comprising ethylene and ethane resulting from step (d) to step (a), wherein carbon dioxide is produced in steps (a) and (c) and is removed in an additional step between steps (b) and (c) and/or between steps (d) and (e).
