(EN) PROCESS FOR PURIFYING A LIPOPHILIC FLUID
(FR) PROCEDE D'EPURATION DE FLUIDE LIPOPHILE
Abrégé
(EN)
A process for purifying dry cleaning solvents from a mixture containing used dry cleaning solvents and contaminants, such as laundry soils, fabric treating agents, the process comprising the steps of: (a) obtaining a mixture comprising a lipophilic fluid and one or more contaminants; (b) chemically modifying the contaminant, (c) contacting the mixture with a purification agent, thereby changing the solubility of the contaminant in the mixture; and (d) separating the contaminant from the lipophilic fluid.
(FR)
La présente invention a trait à un procédé d'épuration de solvants de nettoyage à sec à partir d'un mélange contenant des solvants de nettoyage à sec usagés et des contaminants, tels que des salissures de blanchissage, des agents de traitement de tissu, le procédé comprenant les étapes suivantes : (a) l'obtention d'un mélange comportant un fluide lipophile et un ou des contaminants ; (b) la modification chimique du contaminant ; (c) la mise en contact du mélange avec un agent d'épuration, assurant ainsi la modification de la solubilité du contaminant dans le mélange ; et (d) la séparation du contaminant du fluide lipophile.
