Abstract
A method for separating electrolyte-containing water from an organic phase by means of permeation on a hydrophobic separating means. The permeated organic solution is substantially depleted in water and the retained water is enriched with electrolytes.
Claims20
Method for separating an organic phase from a mixture of an organic phase comprising an organic solution and an aqueous phase comprising an electrolyte-containing water, wherein the mixture to be separated is passed over a hydrophobic porous separating means selected from the group consisting of organophilic membranes, perforated plates and flat textile structures at least a part of the organic phase of the mixture permeating through the separating means while the electrolyte-containing aqueous phase is at least partially retained together with the remainder, if any, of the organic phase.
