The invention relates to distilling industry, especially to the methods of removal of admixtures from alcohol-containing fractions, waste and half-finished products during distillation. A method of removal of admixtures from alcohol-containing fractions during distillation provides for supply into a fractionating column of fractions from a condenser of distillation and alcohol columns, a separator of carbon dioxide and alcohol catchers, fusel oil from alcohol column, fusel wash liquid and hot water for hydro-selection of main and intermediate admixtures, draw off concentrate of main admixtures from the condenser of fractioning column and concentrate of intermediate admixtures from liquid phase of the plate above the point of introduction into the column of hydro-selection water, main fraction of ethyl alcohol from the condenser of an epuration column, fractions from the condensers of distillation, alcohol columns, the separator of carbon dioxide and alcohol catcher, fusel oil from the alcohol column together with fusel liquid is supplied into the middle area of rectifying part of column, hot water for hydro-selection is sent into the lower area of epuration, and still water-alcohol liquid of the fractioning column is directed into the brew. The invention provides for effective removal of the admixtures of alcohol and obtaining alcohol of highest quality. |
