NOVELTY - A method for concentrating and purifying aqueous alcohol solution by use of super-critical fluid comprises: absorbing aqueous alcohol solution into middle part of extraction tube filled with a super-critical fluid; dividing aqueous alcohol solution into a gas phase and a liquid phase; discharging gas phase from the highest section of the extraction tube, obtaining aqueous alcohol solution after separating the super-critical fluid; discharging liquor of liquid phase from lowest section of the extraction tube, and obtaining aqueous alcohol solution after separating the super-critical fluid.    USE - Method for concentrating and purifying alcohol aqueous solution by use of super-critical fluid (claimed).    ADVANTAGE - The alcohol aqueous solution with high concentration is extracted by the principle that azeotropy of the alcohol and water in the alcohol aqueous solution is destroyed by use of super-critical fluid.    DETAILED DESCRIPTION - A method for concentrating and purifying aqueous alcohol solution by use of super-critical fluid comprises: absorbing any of aqueous alcohol solution consisting ethanol, n-propanol or isopropyl alcohol into middle part of extraction tube filled with a super-critical fluid; dividing aqueous alcohol solution into a gas phase and a liquid phase by extraction tube, where the gas phase is flown to the upper section of the extraction tube, while the liquid phase is flown to the lower section of the extraction tube; discharging gas phase from the highest section of the extraction tube, obtaining aqueous alcohol solution with concentration higher than the azeotropic point concentration after separating the super-critical fluid; discharging liquor of liquid phase from lowest section of the extraction tube, and obtaining aqueous alcohol solution with concentration lower than the azeotropic point concentration after separating the super-critical fluid.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of the apparatus for the method of concentrating and purifying alcohol aqueous solution by use of super-critical fluid.
