There is described a method for the treatment and processing of solutions of an organic fluid, water and one or more compounds of alkaline earth metals, alkali metals and metal ions, comprising the following steps: a) conducting a stream ( ) consisting of organic fluid, water and one or more compounds of alkaline earth metals, alkali metals and metals ions to a salt reduction and crystallization unit ( ), b) evaporating and optionally partially condensing the stream ( ) and providing thereby a steam ( ) of evaporated water and organic solvent and a steam ( ) of organic fluid and the compounds of alkaline earth metals, alkali metals and/or metal ions, c) conducting the steam ( ) consisting substantially of organic fluid and the compounds of alkaline earth metals, alkali metals and/or metals ions to a salt reduction means ( ), d) nucleating crystals of the compounds of alkaline earth metals, alkali metals and/or metal ions by means of depressurization and temperature increase, e) removing the portion of the precipitated crystals and/or particles from the organic fluid. The method is particularly well suited for processing of solution consisting of mono-, di, tri, or polyethyleneglycol or mixtures thereof. There is also described a means for carrying out the method.
