Abstract[English]
The present invention relates to a method and device for separating aromatic compounds from a feed (1), the feed comprising a mixture of aromatic and non-aromatic compounds, wherein aromatic compounds are extracted from the feed (1) in a liquid-liquid extractor (T1) supplied with a solvent (2) in order to produce at least one extract (4) concentrated in aromatic compounds relative to the feed (1), and a raffinate (3) concentrated in non-aromatic compounds relative to the composition of the feed (1); and wherein the liquid-liquid extractor (T1) is supplied with the entirety of an extract recycle (5) at one or more positions in the liquid-liquid extractor (T1) arranged between a feed point for the feed (1) and a feed point for the solvent (2).[French]
La présente invention concerne un procédé et un dispositif de séparation de composés aromatiques à partir d'une charge (1) comprenant un mélange de composés aromatiques et non- aromatiques, dans lesquels on extrait des aromatiques de la charge (1) dans un extracteur liquide-liquide (T1) alimenté avec un solvant (2) pour produire au moins un extrait (4) concentré en composés aromatiques par rapport à la charge (1), et un raffinat (3) concentré en composés non-aromatiques par rapport à la composition de la charge (1); et dans lesquels on alimente l'extracteur liquide-liquide (T1) avec la totalité d'un recycle d'extrait (5) à une position ou des positions de l'extracteur liquide-liquide (T1) disposée(s) entre un point d'alimentation de la charge (1) et un point d'alimentation du solvant (2).
