Cyclic rectification technology in alcohol production
(2019) Buliy, Yuri; Shiyan, Peter; Kuts, Anatoly; Melnyk, Iryna
Alternate changing of the steaming periods and liquid overflow allows to intensify mass transfer between liquid and steam and to reduce the specific consumption of heating steam in the process of separation of multicomponent mixtures. The authors propose a technology for rectification, which involves the cyclic motion of the liquid without interrupting of the supply of heating steam and the construction of a rectification column for its implementation. The purpose of the work was to research the effectiveness of the proposed technology in the process of rectification of alcohol-containing fractions and to establish the specific flow rate of steam in the impurity concentration column. The investigations were carried out in the production conditions of the Chudniv branch of SE “Zhytomyr liquor producer ”. To ensure a cyclic mode, the column was equipped with movable liquid transfer devices connected to actuating mechanismes, which acted according to the controller program, and perforated (scale-shaped) trays. The primary task was to determine the hydrodynamic mode of operation of the contact devices - the lower and upper the critical vapor velocity of at which the liquid is retained on the plates and there is its entrainment. It is established that the vapor velocity in the free section of the column can reach 1.2 m/s or more, and in the openings of the scales must exceed the first critical velocity of 6.5-7.5 m/s. The weeping of the tray occurs at the vapor velocity in the holes of 1.5-1 m/s. It is experimentally proved that in the process of rectification of alcohol-containing fractions, the main impurities are removed completely, the degree of extraction of higher fusel alcohols is increased by 38%, methanol - by 15.6%, the multiplicity of concentration of the main impurities is increased by 25%, the higher alcohols - by 40%, methanol – by 34%, acrolein – by 36%. The costs of heating steam are reduced by 30% compared to typical installations and do not exceed 13 kg / dal of absolute alcohol introduced with feed. Exempted from the key impurities the bottom liquid of the impurity concentration column should be used for hydroselection in the purifying column.
Distillation of alcoholic distillate in controlled cycles mode
(2016) Buliy, Yuri; Shiyan, Peter; Kuts, Anatoly
Authors have proposed an innovative technology of alcoholic distillate distillation. The construction of distillation column allows to manage the cycles delay and the liquid overflowing by predetermined algorithm. The design of scaly plates is offered. It allows to increase the intensity of the mass transfer process of volatile liquid and steam components. The expediency of using an innovative technology in production environment is proved. Experimental column with a diameter of 650 mm was equipped with 30 scaly plates with distance of 400 mm and movable valves mounted on rods connected with the cylinders DNT 63-50-PPV-A FESTO. Rods was set in motion in accordance with the controller program. Were used applied contact devices with coaxial arrangement of the arched type scales, with the help of which the principle of gas-liquid jets collision was realized. Founded, that using of the proposed technology allows to optimize the process of alcohol distillation of alcoholic distillate by reducing the specific consumption of heating steam by 35 % compared to a typical distillation columns and the increasing of ethanol concentration in the distillate by 28...30 % with the normative losses of alcohol with stillage. If you increase the interval delay of the mash on the plates of the column more than 12 sec. the specific consumption of heating steam and the alcohol concentration in the distillate is rising insignificantly. This causes the decreasing of column liquid throughput. Proposed design of the contact devices allows to exclude the unidirectionality of the fluid flow, the possibility of stagnant zones formation on the steps of the phase contact, the sticking of alcoholic distillate suspended particles on the surface of the plates and allows to increase the intensity of the mass transfer process of liquid and steam volatile components and extend the lifetime of distillation column without its service stop.

(2017) Shiyan, Peter; Mudrak, Tatiana; Kyrylenko, Roman; Kovalchuk, Svitlana
We theoretically substantiated and experimentally confirmed the feasibility of enriching highly-concentrated wort made from starch-containing raw materials with nitrogen and mineral nutrition for yeast cells. The influence of nitrogen nutrition, as amine and ammoniac nitrogen, as well as mineral nutrition as nanoparticles and ions of metals was investigated. It was established experimentally that in the course of cultivating the yeast on wort with a concentration of 20, 28 % DS, a necessary precondition is the adjustment of nitrogen nutrition through additional introduction of glycine to serve as amine nitrogen, the concentration of 0.7 g/dm3 of wort, and ammoniac nitrogen (to serve as carbamide) in the amount of 800 g/m3, which would make it possible to increase the concentration of yeast cells to 280−430 mln/cm3 in the process of culturing the yeast depending on the concentration of wort and the type of nitrogen nutrition, respectively. Based on results of the present research on the influence of mineral nutrition in the nano- and ionic form on the yeastgeneration process, it was determined that the largest positive effect on the synthesis of yeast cells was exerted by Zn and Mg and the mixtures of these metals, both in nano- and in ionic form, whose concentration was 1.2 mg/cm3 and 50 g/m3, respectively; in this case, the number of yeast cells ranged from 360 to 480 mln/cm3 depending on the concentration of wort and the type of mineral nutrition. We have proven the feasibility of cyclic use of mineral nutrition, both in ionic and in nano forms, when cultivating yeast, in order to obtain cells with high physiological-biochemical activity. The use of mineral and nitrogen nutrition allowed us not only to obtain a high concentration of yeast cells, but also reduce the duration of yeast-generation to 15–20 hours and ensure their high regenerative and physiological activity during fermentation of wort with high concentrations of dry substances.

(2016) Buliy, Yuri; Shiyan, Peter; Kuts, Anatoly
Authors suggest the energy saving technology of the rectification with controllable cycles of delay and overflowing of liquid without interrupting of steam and liquid flows supply in the column due to additionally installed valves on the moving rods along the entire height of the column connected with the driving mechanisms, the action of which is carried out according to the predetermined algorithm.Using of mechatronics subsystems allows to implement full (single) or separated (fractional) liquid overflowing on the plates of the distillation column under conditions of cyclic mode. Technical solution allows to extend the interval of liquid and steam contact.

(2017) Kovalchuk, Svitlana; Shiyan, Peter; Mudrak, Tatiana; Kuts, Anatoly; Kyrylenko, Roman
There was theoretically grounded and experimentally proved the expedience of enriching high-concentrated wort of the starch-containing raw material with such additional source of mineral nutrition for yeast cells as nanoparticles of metals. There was studied the influence of nanoparticles of metals on hydrolysis of biopolymers of the raw material and biosynthesis of organic compounds at wort fermentation. It was experimentally established, that the most positive influence of biosynthetic properties of yeast cells is realized by zinc and magnesium. At using zinc and magnesium, yeast biomass and alcohol content in mashes increase. Best chemical-technological indices of mashes were received at adding nanoparticles of zinc and magnesium at the stage of batch dilution.There was experimentally studied the synthesis of volatile organic admixtures in marsh distillates depending on point of adding nanoparticles of metals. Теоретично обґрунтовано та експериментально підтверджено доцільність збагачення високонцентрованого сусла із крохмалевмісної сировини додатковим джерелом мінерального живлення для дріжджових клітин, в якості наночастинок металів. Досліджено вплив наночастинок металів на гідроліз біополімерів сировини та біосинтез органічних сполук при зброджуванні сусла. Експериментально встановлено, що найбільш позитивний вплив на біосинтетичні властивості дріжджових клітин має цинк та магній. При застосуванні цинку та магнію біомаса дріжджів та вміст спирту в бражках зростає. Найкращі хіміко-технологічні показники бражок отримані при додаванні наночастинок цинку та магнію на стадії розрідження замісу. Експериментально досліджено синтез летких органічних домішок в бражних дистилятах залежно від точки внесення наночастинок металів
