Abstract

FIELD: alcohol industry. SUBSTANCE: method involves boiling extraction of ethyl alcohol from mash in beer (beer frantionating) column with transfer of ethyl alcohol and associated impurities to beer distillate with vapors from beer (beer fractionating) column and liquid fractions from condenser of separator of carbon dioxide and alcohol trap; purification of beer distillate from the main and intermediate impurities including components of fusel oil in rectification column with use of hydroselection; rectification of fractionation intermediate product in alcohol column with separation of fractions of fusel oil, fusel alcohol and nonpasteurized alcohol; rectification of fractions of fusel oil and fusel alcohol from alcohol column in fusel column with withdrawal of fusel oil from accumulating sheet steel cylinder. Novelty of the method consists in that ethyl alcohol is additionally rectified in special column, supplied and heated with steam from beer (beer fractionating) column with withdrawal from its condenser of methanol-ether-aldehyde fraction, and also withdrawal of fusel-ethyl-aldehyde-methanol fractions from alcohol trap, condenser of separator of carbon dioxide and condenser of fractionating column operating with supply of hot water to the upper tray which are additionally used to feed fusel column and withdrawal from its condenser is methane-ether-aldehyde fraction, and withdrawal from zone of 28th-36th trays is fraction of propyl alcohols which are used to feed together with fraction from condensate of special and alcohol column, fractional distillation column. Fed to the middle zone of boiling extraction part of the fractional distillation column is hot water and concentrate of propyl alcohol from liquid phase of tray above introduction of hot water and aqueous-alcohol liquid is withdrawn from vat and directed to initial mash. EFFECT: higher efficiency.

Изобретение относится к спиртовой промышленности, в частности к способам получения ректификованного спирта. Целью изобретения является повышение качества и увеличение выхода ректификованного спирта. Способ получения ректификованного спирта включает вываривание этилового спирта из бражки в бражной (брагоэпюрационной) колонне с переходом этилового спирта и сопутствующих примесей в бражной дистиллят с парами из бражной (брагоэпюрационной) колонны и жидкими фракциями из конденсатора сепаратора диоксида углерода и спиртоловушки, очистку бражного дистиллята от головных и промежуточных примесей, включая компоненты сивушного масла, в эпюрационной колонне с применением гидроселекции, ректификацию эпюрата в спиртовой колонне с выделением фракций сивушного масла, сивушного спирта и непастеризованного спирта, ректификацию фракций сивушного масла и сивушного спирта из спиртовой колонны в сивушной колонне с отбором сивушного масла из аккумуляторной царги. Новым является то, что этиловый спирт дополнительно очищают в специальной колонне, питаемой и обогреваемой паром из бражной (брагоэпюрационной) колонны с отбором из ее конденсатора метанольно-эфироальдегидной фракции, а также отбором сивушно-эфироальдегидометанольных фракций из спиртоловушки, конденсатора сепаратора диоксида углерода и конденсатора работающей с подачей горячей воды на верхнюю тарелку эпюрационной колонны, которыми дополнительно питают сивушную колонну и отбирают из ее конденсатора метанольно-эфироальдегидную фракцию, а из зоны 28 - 36-й тарелок - фракцию пропиловых спиртов, которыми совместно с фракциями из конденсаторов специальной и спиртовой колонн питают разгонную колонну, в среднюю зону выварной части которой подают горячую воду, из конденсатора отбирают концентрат головной фракции, из жидкой фазы тарелки над вводом горячей воды - концентрат пропиловых спиртов, а из куба выводят водно-спиртовую жидкость и направляют ее в исходную бражку.The invention relates to the alcohol industry, in particular to methods for producing rectified alcohol. The aim of the invention is to improve the quality and increase the yield of rectified alcohol. A method for producing rectified alcohol involves digesting ethyl alcohol from the mash in a mash (mash), with the passage of ethyl alcohol and associated impurities into the mash distillate with vapors from the mash (mash), and liquid fractions from the condenser of the carbon dioxide and alcohol distillation separator separator, and intermediate impurities, including fusel oil components, in a scrubbing column using hydroselection, distillation of the epurate in an alcohol column with isolation eat fractions of fusel oil, fusel alcohol and unpasteurized alcohol, rectification of fractions of fusel oil and fusel alcohol from an alcohol column in a fusel string with the selection of fusel oil from the battery tray. New is that ethyl alcohol is additionally purified in a special column fed and heated with steam from the mash (ephemeral) column with the selection of methanol-ether-aldehyde fraction from its condenser, as well as the selection of fusel-ether-aldehyde methanol fractions from the alcohol trap, the condenser of the carbon dioxide separator and with the supply of hot water to the upper plate of the epilation column, which additionally feed the fusel column and methanol-ether-aldehyde fraction is taken from its condenser a fraction of propyl alcohols, which together with fractions from condensers of a special and alcohol columns feed a booster column into the middle zone of the boiled portion of which hot water is supplied, the head fraction is taken from the condenser from the liquid phase plates over the input of hot water - a concentrate of propyl alcohols, and water-alcohol liquid is removed from the cube and sent to the original mash.
