METHOD OF PRODUCING RECTIFIED ALCOHOL Russian patent published in 2016 - IPC C12P7/06 

FIELD: alcohol industry.

SUBSTANCE: invention relates to alcohol industry. Method of producing rectified alcohol includes distillation processes, which are carried out in operating under atmospheric pressure brew epuration-, epuration-, boiling extraction-, booster- and preliminary purification columns, and, under vacuum - in alcohol column, final purification column, and a column for boosting head- and tail fractions. Brew epuration-, epuration-, boiling extraction- and booster columns are heated by live steam, preliminary purification column is heated by water-alcohol vapour from the first brew heater and, additionally - by condensate from carbon dioxide separator condenser. Initial brew is heated to 85-88 °C by the heat of heating steam condensate, while hydro selection water is heated to 95-97 °C by Luther's heat from the boiling extraction-, epuration- and booster columns and by the heat of steam condensation in the first dephlegmator of the epuration column. Alcohol is cleaned of head impurities in the preliminary purification column and in operating under vacuum alcohol column, final purification column, column for boosting of head and tail fractions.

EFFECT: invention allows to manufacture a product of high quality, increase its yield and reduce power consumption.
