Abstract[English]
A process and a system for oxidative dehydrogenation ("ODH") of hydrocarbons are provided. An exemplary process includes contacting an ethane feed with an oxidant in the presence of an oxidative dehydrogenation catalyst in an oxidative dehydrogenation reactor under oxidative dehydrogenation conditions to produce an output stream. The ethane feed includes ethane. The output stream includes ethylene, acetic acid, and residual ethane from the ethane feed. The process includes contacting the output stream with an acetate in an absorber to separate a product stream from a residual ethane stream. The product stream includes the ethylene. The residual stream includes the residual ethane from the ethane feed.[French]
L'invention concerne un procédé et un système de déshydrogénation oxydative ("ODH") d'hydrocarbures. Un procédé donné à titre d'exemple comprend la mise en contact d'une charge d'éthane avec un oxydant en présence d'un catalyseur de déshydrogénation oxydative dans un réacteur de déshydrogénation oxydative dans des conditions de déshydrogénation oxydative pour produire un flux de sortie. La charge d'éthane comprend de l'éthane. Le flux de sortie comprend de l'éthylène, de l'acide acétique et de l'éthane résiduel provenant de la charge d'éthane. Le procédé comprend la mise en contact du flux de sortie avec un acétate dans un absorbeur pour séparer un flux de produit d'un flux d'éthane résiduel. Le flux de produit comprend de l'éthylène. Le flux résiduel comprend l'éthane résiduel provenant de la charge d'éthane.
