Title (EN) AROMATICS SEPARATION FROM PETROLEUM STREAMS
(FR) PURIFICATION D'ELEMENTS AROMATIQUES ISSUS D'ECOULEMENTS DE PETROLE
Abstract: front page image
(EN)A process for separating a feed mixture comprising at least one aromatic hydrocarbon and at least one non-aromatic hydrocarbon by extractive distillation (ED) utilizing a solvent mixture comprising sulfolane and at least one co-solvent. The co-solvent is an alkyl sulfolane having from 4 to 8 carbon atoms per molecule. The solvent mixture is added to the top of the ED column, and the feed mixture is added at a point on the ED column that is lower than the point where the solvent mixture is added. Extractive distillation is performed, and the aromatic and non-aromatic hydrocarbons are separated.
(FR)La présente invention concerne un processus permettant de séparer un mélange alimentaire comprenant au moins un hydrocarbure aromatique et au moins un hydrocarbure non aromatique par distillation extractive (ED) par l'utilisation d'un mélange de solvants comprenant du sulfonlane et au moins un co-solvant. Ce co-solvant est un sulfonlane alkyle possédant de 4 à 8 atomes de carbone par molécule. Ce mélange de solvants est ajouté en tête de la colonne ED, et le mélange alimentaire est ajouté à un point de la colonne ED qui est plus bas que le point où le mélange de solvant est ajouté. On réalise la distillation extractive et on sépare les hydrocarbures aromatiques et non aromatiques.
