Abstract
A method for removing one or more congeners from an alcoholic composition, including placing a quantity of an alcoholic composition in a pressure-controllable environment, decreasing the pressure of the pressure-controllable environment, removing one or more unwanted congeners from the alcoholic composition to yield a purified alcoholic composition, and removing the purified alcoholic composition from the pressure-controllable environment.
Claims25
A method for removing ethyl acetate from an alcoholic composition, comprising:
- a) placing a quantity of alcoholic composition in a pressure-controllable environment;
- b) decreasing a pressure of the pressure controllable environment to a pressure between eighty and forty Torr;
- c) holding the pressure of the pressure-controllable environment at between eighty and forty Torr for a first predetermined period of time;
- d) preferentially removing ethyl acetate relative to other congeners of a group of congeners from the alcoholic composition to yield a first purified alcoholic composition;
- and
- e) removing the first purified alcoholic composition from the pressure controllable environment.
A method for removing ethyl acetate from an alcoholic composition, comprising:
- a) establishing a partial vacuum in a pressure vessel;
- b) flowing a quantity of alcoholic composition into the pressure vessel;
- c) at least partially preferentially removing ethyl acetate relative to acetaldehyde or ethanol from the alcoholic composition to yield a purified alcoholic composition;
- and
- d) extracting the purified alcoholic composition from the pressure vessel;
- wherein, while in the pressure vessel, the alcoholic composition remains liquid.
A method for removing ethyl acetate from an alcohol composition, comprising:
- a) placing a quantity of an unpurified aqueous solution of alcohol in a pressure and temperature-controllable environment;
- b) decreasing a pressure of the pressure and temperature-controllable environment to a pressure between eighty and twenty Torr;
- c) holding the pressure of the pressure and temperature-controllable environment at between eighty and twenty Torr for a first predetermined period of time;
- d) preferentially removing ethyl acetate relative to molecules with different molecular weights than the ethyl acetate from the unpurified aqueous solution of alcohol to yield a first purified aqueous solution of alcohol;
- and
- e) removing the first purified aqueous solution of alcohol from the pressure and temperature-controllable environment;
- wherein the first purified aqueous solution of alcohol has substantially the same composition as the unpurified aqueous solution of alcohol with the exception being that the first purified aqueous solution of alcohol contains substantially less ethyl acetate than the unpurified aqueous solution of alcohol, and
- wherein during c), a temperature within the pressure and temperature-controllable environment is controlled such that substantially only ethyl acetate is removed from the unpurified aqueous solution in the pressure and temperature-controllable environment.
A method for selectively removing ethyl acetate from an alcoholic composition, comprising:
- a) establishing a partial vacuum in a pressure vessel;
- b) flowing a quantity of alcoholic composition into the pressure vessel wherein the alcoholic composition is further comprised of a plurality of components, one of which is ethyl acetate;
- c) at least partially preferentially removing ethyl acetate relative to congeners with higher vapor pressure and lower boiling point than ethyl acetate from the alcoholic composition to yield a purified alcoholic composition;
- and
- d) extracting the purified alcoholic composition from the pressure vessel,
- wherein, while in the pressure vessel, the alcoholic composition remains liquid, and
- wherein temperature and pressure conditions within the pressure vessel permit selectively removing ethyl acetate from the alcoholic composition without substantially decreasing relative concentration of any remaining component.
