Abstract

On décrit un procédé de purification de courants de solution acqueuse d'acide provenant de la cuve de décantation pour l'enlèvement des impuretés azotées, ce procédé comprenant les étapes qui consistent à (a) neutraliser le courant de solution acqueuse d'acide; (b) mettre en contact le courant résultant avec un courant d'hydrocarbures choisis parmi les hydrocarbures riches en fractions aromatiques ou les hydrocarbures naphténiques, de manière à former une émulsion; (c) envoyer cette émulsion dans un décanteur où l'on récupère le courant de solution acide neutralisé et purifié d'une part et une phase organique d'autre part.
