Abstract

See full text

The present invention is a process for purifying a liquid stream having an aqueous phase with polyaromatics, and optionally an organic phase. The process can include sending the liquid stream to a mixing tank and introducing an aromatic component to produce a mixture of an organic phase and of an aqueous phase. The mixture can be sent to a decanter to recover a clean aqueous phase and an organic phase. The clean aqueous phase can go through a stripper to remove a substantial part of any remaining organic component. The liquid stream can be the whole or a fraction of an aqueous phase recovered by condensation of an effluent gas leaving an ethylbenzene dehydrogenation reactor.
