<p>A process for treating an aqueous phase obtained by acidic or basic washing of a hydrocarbon phase comprising a soluble aluminum compound in solution, characterized in that it is neutralized at a pH of from 6 to 8.5, treated with an additive selected from the alkaline-earth metal oxides, hydroxides and carbonates, at a temperature ranging from 90 DEG C. to the boiling point, the molar ratio of the additive to aluminum being from 1/10 to 10/1, and separated thereafter from the insoluble phase of precipitate.</p> |
