Abstract[English]
A feed stream including ethane is flowed to a purification unit that includes a first oxidative dehydrogenation catalyst. The feed stream is contacted with the first oxidative dehydrogenation catalyst at a first temperature to reduce a concentration of impurities in the feed stream to produce a purified feed stream. The purified feed stream is flowed to an oxidative dehydrogenation unit that includes a second oxidative dehydrogenation catalyst. The purified feed stream is contacted with the second oxidative dehydrogenation catalyst in the presence of oxygen at a second temperature greater than the first temperature to dehydrogenate ethane to produce a product stream that includes ethylene.[French]
Un flux d'alimentation comprenant de l'éthane est amené à s'écouler vers une unité de purification qui comprend un premier catalyseur de déshydrogénation oxydative. Le flux d'alimentation est mis en contact avec le premier catalyseur de déshydrogénation oxydative à une première température pour réduire la concentration d'impuretés dans le flux d'alimentation afin de produire un flux d'alimentation purifié. Le flux d'alimentation purifié est amené à s'écouler vers une unité de déshydrogénation oxydative qui comprend un second catalyseur de déshydrogénation oxydative. Le flux d'alimentation purifié est mis en contact avec le second catalyseur de déshydrogénation oxydative en présence d'oxygène à une seconde température supérieure à la première température pour déshydrogéner l'éthane afin de produire un flux de produit qui comprend de l'éthylène.
