  • Method for separating multi-phase mixtures of solvents having small differences in density
    Patent number: 6447685
    Abstract: The invention relates to an apparatus for separating water-containing solvent mixtures having two or more phases, using one or two gravitational separators (4, 16) and to the use of this apparatus, and also to a process for separating water-containing solvent mixtures having two or more phases. Using the novel apparatus it is possible to separate even small-density-difference solvent mixtures having two or more phases. To this end, a coalescence separator (1) has been provided upstream of the first gravitational separator (4).
