<p>A feedstream containing components which form a homogeneous binary azeotrope is subjected to distillation but, prior to the distillation, it is contacted with a third component with respect to which the azeotrope forming components of the feed have substantially different solubilites, the resulting mixture being allowed to separate in a decanting vessel (52) to form two liquid phases (58, 60) in which the concentrations of the azeotroping components are significantly different from the azeotropic composition. The resulting liquid phases are supplied to respective distillation columns (54, 56) to produce bottoms products essentially consisting of the components to be separated, each substantially free of the other component.</p> |
