<p>The present invention is a process for purifying a liquid stream comprising an aqueous phase and optionally an organic phase,
said aqueous phase comprising polyaromatics in solution in water,
wherein,
a) said liquid stream is sent to a mixing tank in which is introduced an effective amount of an aromatic component, advantageously ethylbenzene or benzene or toluene or mixture thereof to produce a mixture of an organic phase and of an aqueous phase,
b) then said mixture recovered at step a) is sent to a decanter to recover a clean aqueous phase and an organic phase. According to a specific embodiment the stream sent to step a) is the whole or a fraction of the aqueous phase recovered by condensation of the effluent gas leaving an ethylbenzene dehydrogenation reactor.</p> |
