METHOD FOR COPRODUCTION OF RECTIFIED ETHANOL AND GRAIN DISTILLATE Russian patent published in 2018 - IPC C12P7/06 B01D3/14 

FIELD: alcohol industry.

SUBSTANCE: invention relates to alcohol industry. Method for coproduction of rectified ethanol and distillate involves digestion of ethanol from the mash in a crocheted column with the transition of alcohol and co-impurities to the melt distillate, withdrawn from the liquid phase of the upper strengthening plates of this column and divided into two streams; purification of the distillate used to produce rectified ethyl alcohol from the head and intermediate impurities in the column, rectification of the epurate in an alcohol column with the selection of fractions of fusel oil, fusel alcohol and unpasteurized alcohol, separation of fractions containing head and intermediate compounds, extraction of head impurities and methanol in the final purification column, concentration of contaminants in the fusel column, rectification of the water-ethanol liquid in the raw column.

EFFECT: method allows simultaneous production of alcohol and distillate with an increased yield.
