Abstract: A plant for dealcoholising alcoholic beverages includes a rectification column having at least one inlet for the alcoholic beverage, a sump and a top. The rectification column is operable such that dealcoholised beverage can be removed from the sump and exhaust vapour can be removed from the top. At least one evaporator is configured to supply the rectification column with vapour. A condenser arrangement condenses the exhaust vapour removed from the top of the rectification column, at least in part. The plant further includes a heat pump which can operate the evaporator as well as the condenser arrangement. A method for dealcoholising alcoholic beverages in a rectification column is also disclosed.

Abstract: In order to separate and concentrate a liquid component from a liquid multi-component mixture formed of several liquid components with different boiling temperatures, e.g. an ethanol-water mixture, a concentration apparatus (3) is proposed, with its separation section and concentration section designed as separate columns (5, 7) with different operating energy requirements. The column (7) with the higher operating energy requirements is designed for a lower temperature difference between the boiling temperature of the top of the column (29) and the boiling temperature of the bottom of the column (21) than the column (5) with lower operating energy requirements. Separate mechanical vapour compressors (15, 27) are assigned to the two columns (5, 7), said vapour compressors compressing the vapours from the top of the associated column (5, 7) and supplying the operating energy to the bottom region (11, 21) of the respective column (5, 7) by means of separate sump evaporators (9, 23) which act as, reboilers.
