INCREASING THE DEGREE OF EXTRACTION OF ORGANIC IMPURITIES OF RECTIFIED ALCOHOL

Obtaining high quality rectified ethyl alcohol is a priority for the further development of industry. The solution to this urgent problem possible under condition deeper extraction and concentration volatile impurities on plates column equipment Distillation/Rectification Unit.
 In columns Unit simultaneously with release due esterification reaction formation organic compounds that degrade its reduce yield final product. Thus, during interaction alcohols, acids, aldehydes, breakdown products amino sulfur compounds, other components brew in fermentation are esters, acetals acids.
 aim work was determine optimal technological modes distillation alcohol-containing intermediate by-products distillation/rectification process accelerating column, epuration wash distillate repeated clearance, which content would be lowest.
 Materials methods. Research methods were analytical, chemical, physico-chemical use instruments research used production alcohol. determined gas chromatograph HP FFAP 50 m × 0.32 m. It increase degree it necessary ensure bottom does not exceed 4% vol.; pasteurization zone rectification 10 plates, ethanol epurate 22-29% by hydroselection impurities; free column. To improve energy consumption extending contact time steam liquid, promising direction mass transfer cyclic mode. proposed measures require constant monitoring parameters provide operation an automated
