Method for removing salts, which cannot be thermally regenerated in a temperature range from 0°C to 200°C, from organic solvents in aqueous solution by evaporation, wherein the normal boiling point of the organic solvents is higher than that of water, and wherein the organic components which are contained in the solvent and the salt-like components which are contained in the organic components are enriched by evaporating water and a portion of the organic components in a liquid phase which is formed in a first container, and wherein a vapour phase which is formed is discharged from the first container. In particular, in this context the liquid phase which is formed in the first container is fed into a second container, wherein water in a vapour and/or in a liquid form is directed into the second container, wherein water and a further component of the organic component which is contained in the solvent are evaporated and a form of vapour phase which is discharged from the second container, wherein the salt-like components are concentrated in the liquid phase which is forming in the second container, and wherein a partial stream of the liquid phase which is formed in the second container is discharged from the second container. |
