Title (EN) IMPROVED EXTRACTIVE DISTILLATION PROCESSES USING WATER-SOLUBLE EXTRACTIVE SOLVENTS
(FR) PROCÉDÉS AMÉLIORÉS DE DISTILLATION EXTRACTIVE UTILISANT DES SOLVANTS D'EXTRACTION SOLUBLES DANS L'EAU
Abstract: front page image
(EN)Extractive distillation processes whereby water-soluble extractive distillation (ED) solvents are regenerated and recovered employ improved operations of the extractive distillation column (EDC) so that polar hydrocarbons are recovered and purified from mixtures containing polar and less polar hydrocarbons and measurable amounts of hydrocarbons that are heavier than intended feedstock and/or polymers that are generated in the ED process. The improved process can effectively remove and recover the heavy hydrocarbons and/or remove polymer contaminants from the solvent in a closed solvent circulating loop through mild operating conditions with no additional process energy being expended. With the improved process, the overhead reflux of the EDC may be eliminated to further reduce energy consumption and to enhance the loading and performance within the upper portion of the EDC, especially when two liquid phases exists therein.
(FR)L'invention concerne des procédés de distillation extractive dans lesquels des solvants de distillation extractive (ED) solubles dans l'eau sont régénérés et récupérés en recourant à des améliorations du fonctionnement de la colonne de distillation extractive (EDC) de manière à récupérer les hydrocarbures polaires et les purifier à partir de mélanges qui contiennent des hydrocarbures polaires et des hydrocarbures moins polaires et des quantités mesurables d'hydrocarbures plus lourds que les produits voulus et/ou les polymères produits dans le procédé d'ED. Le procédé amélioré permet d'extraire et de récupérer efficacement les hydrocarbures lourds et/ou d'éliminer les contaminants polymères du solvant dans une boucle fermée de recirculation du solvant, dans des conditions de traitement modérées sans dépense d'énergie supplémentaire de traitement. Avec le procédé amélioré, on peut éliminer le reflux en tête de l'EDC pour encore réduire la consommation en énergie et améliorer la charge et les performances de la partie supérieure de l'EDC, en particulier lorsque deux phases liquides y coexistent.
