Документ Energy-saving rectification technology with controlled mass exchange cycles between liquid and vapor(2021) Buliy, Yuri; Kuts, Anatoly; Forsyuk, Andriy; Chumachenko, SergiiPurpose of the article: the definition of the hydrodynamic mode of operation of barbotage perforated plates, of the efficiency of the technology of cyclic rectification in the mass-exchange columns equipped with barbotage perforated plates with variable free cross-sectionin and determining the consumption of heating steam in the rectificational and epyuratin columns. Research methods - analytical, chemical, physico-chemical with the use of instruments and research methods used in the production of rectified ethyl alcohol. Fluid consumption was controlled with the help of flowmeter RM, air velocity in the free section of the column - anemometer MS-13, in the holes of the plates - by calculation method. The concentration of volatile impurities of alcohol was determined on a gas chromatograph with a column HP FFAP 50 m × 0.32 m. Analysis of research samples was performed according to the State Standard of Ukraine 4222:2003 "Vodka, ethyl alcohol and water-alcohol solutions. Gas chromatographic method for determination of microcomponents content". An energy-saving technology of cyclic rectification with a continuous supply of heating steam and liquid to a mass-exchange column apparatus equipped with flake plates is proposed. The innovative method allows to prolong the time of contact of steam and liquid on plates up to 40-60 s and to reduce the time of overflow up to 1-1,7 s. In order to implement the technology, a rectification column design was proposed, equipped with flake plates with variable free cross-section.Документ Improving the efficiency of mass-exchange between liquid and steam in rectification columns of cyclic action(2021) Buliy, Yuri; Kuts, Anatoly; Yuryk, Ivan; Forsyuk, AndriyThe purpose of the work was to determine the optimal time of residence of the liquid on the plates, the grade of extraction and concentration ratio of volatile impurities of alcohol and the specific consumption of heating steam in rectification columns of cyclic action. The studies were carried out in a rectification column, equipped with flaky plates with a variable free cross-section. Concentration of alcohol volatile impurities was determined by chromatographic method, the grade of their extraction and concentration ratio – by calculation method, other indicators – by commonly known methods. The maximum extraction of volatile impurities was being achieved in a rectification column, equipped with flaky plates containing turnaround sections connected to drive mechanisms, the action of which is occurred according to a given algorithm. The optimal parameters of operating the column were: vapor velocity in the orifices of the flakes during the period of liquid retention on the plates 12-14 m/s; during liquid pouring 1-1.5 m/s; time of residence of the liquid on the plates 40 s, pouring time 1.7 s; pressure in the lower part of the column 12 kPa; the concentration of ethyl alcohol in the still liquid 3-4% vol. In order to provide the cycles, the free sectional area of the plates must change instantaneously from 5.5 to 51.7%. This technical solution allows to provide complete disposal of ethers, methyl acetate and isopropyl alcohol, to increase the grade of extraction of higher alcohols of sivush oil and methanol by 38%, the concentration ratio of aldehydes by 25%, higher alcohols by 38%, methanol by 37%, and to reduce specific consumption of heating steam by 40% compared to a typical column operating in stationary mode.Документ Antioxidant ability of alcoholic infusions from vegetable raw materials for the technology of alcoholic beverages(2020) Kuzmin, Oleg; Kucherenko, Volodymyr; Stukalska (Ivanova), Nataliia; Kuts, Anatoly; Oliynyk, Svitlana; Rakhmetov, DzhamalThe work is devoted to the development of scientific foundations of the antioxidant activity of aqueous-alcoholic infusions from plant raw materials and the identification of the most promising plants as sources of natural antioxidants. The creation of alcoholic tinctures with an antioxidant effect makes it possible to bring to the market new products that favorably distinguish the range of manufacturers from the range of competitors, creating a positive image of the company. Expansion of the range of alcoholic beverages with the use of alcoholic beverages from plant raw materials to enhance the antioxidant effect has been substantiated.Документ Water-alcohol adsorbing cleaning out of higher alcohols by shungite(2014) Melnyk, Lyudmila; Turchun, Oleg; Melnyk (Tkachuk), Nataliia; Kuts, Anatoly; Melnyk, ZinoviyThe aim of the research work is to increase the quality and safety of high spirits solutions at the expense of using natural adsorbent shungite.
