| description | A process (100) is proposed for producing ethylene by subjecting ethane in a reaction feed to partial catalytic conversion by oxidative dehydrogenation (1) in the presence of oxygen to give a gaseousfirst mixture of components that comprises at least ethane, ethylene, acetic acid and water. In this process, at least a portion of the gaseous first mixture of components is scrubbed with a scrubbingliquid to give a liquid second mixture of components, that comprises water and acetic acid; a first fraction of the second mixture of components is used to form the scrubbing liquid; a second fraction of the second mixture of components is subjected to solvent extraction to give a liquid third mixture of components, that comprises at least one organic solvent and acetic acid; and at least a portion of the liquid third mixture of components is heated and distilled to give a liquid containing predominantly or exclusively acetic acid. The heating of the third mixture of components or of its distilled portion is performed |
