Abstract
The present invention relates to a method and device for separating aromatic compounds from a feed (1) comprising a mixture of aromatic and non-aromatic compounds, wherein aromatics are extracted from the feed (1) in a liquid-liquid extractor (T1) fed with a solvent (2) to produce at least one extract (4) concentrated in aromatic compounds relative to the feed (1), and one raffinate (3) concentrated in non-aromatic compounds relative to the composition of the feed (1); and wherein the liquid-liquid extractor (T1) is fed with all of a recycle of the extract (5) at one or more positions of the liquid-liquid extractor (T1) arranged between a feed point (1) and a solvent feed point (2).
