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 first distillation column, epuration-, boiling extraction- and booster columns, and, under vacuum - in an alcohol column, preliminary purification columns, final purification column, methanol and head impurities concentration column, second distillation column. Initial brew is heated to 85-88 °C by heating steam condensate, while hydraulic selection water is heated to 95-97 °C by Luther's heat from boiling extraction-, epuration- and booster columns. Ethyl alcohol is fine cleaned of impurities in the epuration and booster columns, to top plates of which hydro-selected water is supplied. Purification of alcohol from methanol, acetic aldehyde and other head impurities is carried out in the preliminary purification column and in operating under vacuum alcohol column, final cleaning column, methanol and head impurities concentration column, with extraction of concentrate of these impurities from condensers of the columns for preliminary purification and methanol and head impurities concentration.EFFECT: invention allows to manufacture a high quality product with low production costs.1 cl, 1 dwg, 2 tbl, 2 ex |
