Title (EN) PROCESS FOR THE SEPARATION OF AN ALKYLENE GLYCOL
(FR) PROCÉDÉ POUR LA SÉPARATION D'UN ALKYLÈNE GLYCOL
Abstract: front page image
(EN)The invention provides a process for the recovery of an alkylene glycol from an aqueous stream comprising the alkylene glycol and the corresponding dialkylene glycol, said process comprising the steps of providing the aqueous stream comprising the alkylene glycol and the corresponding dialkylene glycol, providing a first solvent stream, combining said aqueous stream comprising the alkylene glycol and the corresponding dialkylene glycol with said first solvent stream and recovering at least a portion of the alkylene glycol by liquid-liquid extraction, wherein said solvent comprises an amine.
(FR)L'invention concerne un procédé pour la récupération d'un alkylène glycol à partir d'un courant aqueux comprenant l'alkylène glycol et le dialkylène glycol correspondant. Ledit procédé comprend les étapes d'apport d'un courant aqueux comprenant l'alkylène glycol et le dialkylène glycol correspondant, d'apport d'un premier courant de solvant, de combinaison dudit courant aqueux comprenant l'alkylène glycol et le dialkylène glycol correspondant avec ledit premier courant de solvant et de récupération d'au moins une partie de l'alkylène glycol par extraction liquide-liquide, ledit solvant comprenant une amine.
