Abstract

Separation of aqueous mixtures containing organic solvents, in particular mixtures resulting from regeneration of activated carbon filters with steam and separation of the condensate into an aqueous mixture containing organic solvents and a substantially anhydrous organic phase, into an aqueous phase having a low content of organic solvents and a substantially anhydrous organic phase is carried out by separating in a separator plant the aqueous mixture containing organic solvent(s) into an aqueous phase substantially free of organic solvent(s) and an aqueous mixture of organic solvent(s), and extracting at least part of the aqueous mixture of organic solvent(s) with the substantially anhydrous organic phase or with an organic liquid analogous thereto to form an aqueous phase having a low content of organic solvent(s), which aqueous phase is recycled to the separator plant, and an organic phase having a low water content. The resulting organic phase may be treated to remove water. <IMAGE>
