ABSTRACT:
Ethylbenzene is produced by the alkylation of benzene and subsequently catalytically dehydrogenated to produce styrene in a process wherein a benzene sidecut stream removed from the fractionation zone separating the newly produced ethylbenzene is water washed to remove a boron-containing complex. The washed sidecut stream is then utilized as the solvent stream fed to a liquid-liquid extraction zone which treats a water stream formed by condensing the effluent of a dehydrogenation zone. The treated water stream is used to generate steam and the extract stream removed from the extraction zone is combined with the effluent of the dehydrogenation zone to cool and dilute the effluent and to recover styrene and ethylbenzene.
