Abstract
A process for the dehydrogenation of alkylaromatic hydrocarbons, such as ethylbenzene, in which a water stream formed by condensing and separating the effluent of the reaction zone is treated for the removal of alkenylaromatic hydrocarbons by passage through a liquid-liquid extraction zone, and the alkenylaromatic hydrocarbons are then recovered by admixing the extract stream with the effluent as part of the cooling performed before the effluent is passed into a liquid phase separation zone.
