METHOD OF PRODUCTION OF A RECTIFIED ALCOHOL Russian patent published in 2005 - IPC

FIELD: distillery industry; production of alcohol.

SUBSTANCE: the invention presents a method of production of a rectified alcohol and is dealt with the field of a distillery industry, in particular with methods of production of a food rectified alcohol. The method provides for digestion of the alcohol from a brew in a brew column with transition of ethyl alcohol and accompanying impurities together and with a vapor from this column in a brew distillate, purification of the brew distillate from the head and intermediate impurities including components of the fusel oil in an epuration column with feeding of hot water onto its upper plate, fractionation of the epurate in the alcohol column with separation of fractions of fusel oil, fusel alcohol and unpasteurized alcohol, distillation of fractions of the head and intermediate impurities of the ethyl alcohol in the distillation column. The faction of fusel alcohol is separated from a vapor phase of the 16-40-s plates of an alcohol column and direct to a vapor phase of a bottom of an additional column, onto the upper plate of which hot water is fed. From the condenser of the additional column they separate a concentrate of intermediate impurities. The bottom liquid of the additional column is directed together with factions from condensers of alcohol and methanol columns, as well as alcohol trappers of clear distillates onto the upper plate of the distillation column. the alcohol traps of pure distillates. Hot water is fed into the upper zone of the distillation column for hydroselection of the head impurities, propyl alcohols and other intermediate impurities, which are extracted from the condenser of this column in the form of a concentrate of the head impurities and propyl alcohols, and the bottom liquid of the distillation column is directed on a feeding plate of the epuration column. The invention allows to raise quality of alcohol.

EFFECT: the invention allows to raise quality of alcohol.
