Документ Improving the method of determin-ing the mass fraction of magnesium carbonate and the study of the chemical composition of carbonate rocks for the effective conduct of the technological process of sugar production(2021) Kos, Tatiana; Kuznietsova, Inha; Sheiko, Tamila; Khomichak, Liubomyr; Bal-Prylypko, Larysa; Vasyliv, Volodymyr; Gudzenko, Maxim; Nikolaenko, Mykola; Bondar, Nikolai; Haidai, IrinaThe article considers an improved method for determining the content of magnesium carbonate in the carbonate rock. An adjusted method for determining the content of magnesium carbonate was included in the complete establishment of chemical analysis of limestone, which includes the determination of moisture, impurities insoluble in hydrochloric acid, the amount of one and a half oxides of aluminum and iron, calcium carbonate and magnesium carbonate (advanced method), calcium sulfate, alkali metal oxides of potassium and sodium. The obtained experimental data were entered into a single table and summed up the material balance of all components of the carbonate rock. As a result, it was found that this technique includes the following criteria: it is the most accurate, most accessible, and cheap. The use of adjusted methods for determining the content of calcium and magnesium carbonate in limestone will make it possible to establish the objective chemical composition of the carbonate rock and avoid several technological problems. Namely, the excess of uncontrolled magnesium carbonate contributes to the formation of the liquid phase, which in turn reduces the concentration of chemically active lime and promotes the formation of melts in the lime kiln, deteriorating filtration rates, clogging the evaporating station, and so on. Therefore, having information about the real component composition of limestone, the technologist will be able to adjust the technological process in advance, which will lead to the preservation of natural resources while the quality of finished products will not decrease.Документ The use of poliheksamethyleneguanidine (phmg) salts in alcohol production from starch-containing raw materials(2021) Boiko, Petro; Bondar, Nikolai; Kuts, AnatolyДоцільність використання солей полігексаметиленгуанідину (ПГМГ) як антисептика при виробництві спирту з крохмалевмісної сировини.

Technological and economic features of manufacture(2020) Boiko, Petro; Bondar, NikolaiУ статті розглядаються питання виробництва технічного етанолу із зерна як типового продукту сільського господарства України з точки зору поєднання технологічних заходів та визначення економічної доцільності збуту продукції на різних ринках. Уточнюється, що специфікою такого впровадження є конкуренція технічного етанолу та продуктів нафтогазоорганічного синтезу. Розглянуто ряд заходів, які при незначних величинах їх реалізації забезпечують зниження собівартості технічної переробки зерна на технічний етиловий спирт. The article deals with the issues of producing technical ethanol from the grain as a typical Ukrainian agricul ture product in terms of the combination of technological measures and the determination of the economic feasi bility of marketing products in different markets. It is specified that the specifics of such implementation are com petition of technical ethanol and products of oil and gas-organic synthesis. A number of measures are considered, which, at insignificant values of their implementation, provide a reduction in the cost of technical processing of grain into technical ethanol.Документ The biorefinery of second generation - new resourses, technologies and ideas(2020) Boiko, Petro; Bondar, Nikolai; Kuts, AnatolyУ цій статті ми описуємо перспективи виробництва біоетанолу НПЗ ІІ генерації, в тому числі з целюлози як сировини.In this artical we describe the perspectives of bioethanol production by the refinery of second generation, including from cellulose as a raw material.Документ The technology of the second generation of bioethanol(2018) Boiko, Petro; Bondar, Nikolai; Kuts, AnatolyУ цій статті ми описуємо практичне виконання другої та заключної частини технологія газифікації біомаси у виробництві біоетанолу (паливного етанолу). Ця частина є перетворення синтез-газу в етанол за допомогою мікроорганізмів. Умови життя мікроорганізмів залежить від багатьох умов: температури, pH, впливу інгібіторів та/або активаторів. Це все умови дають змогу реалізувати промислове виробництво біоетанолу з целюлози. In this article we describe the practilal realazing of the second and final part of the technology of biomass gasification in the bioethanol (fuel ethanol) production. This part is the conversion of syngas to ethanol using the microorganisms. The living conditions of microorganisms depends from meny conditions: temperature, pH, ingibitors and/or activators influence. This all conditions give as realize the industrial volume production of bioethanol from cellulose.Документ Innovative technologies of bioconvertion of renewable raw materials in etanol(2022) Babich, Irina; Boiko, Petro; Bondar, Nikolai; Kuts, AnatolyУ статті розглядається інноваційна технологія біоконверсії відновлюваної сировини в етанол.

The paper considers technological aspects extraction of alcohol from mash in the production of fuel alcohol.Документ Aspects of ethanol manufacture. Different purpose – different technological and economic solutions(2022) Babich, Irina; Boiko, Petro; Bondar, Nikolai; Kuts, AnatolyThe article analyzes the reasons that led to the almost catastrophic situation in the ethanol industry of the country. The existing structure of consumption of ethanol in the domestic market, when the lion's share of ethanol is used to produce alcoholic beverages, together with the actual monopolization of pricing policies, have led to the fact that spirits can produce significantly more volumes of ethanol than the market needs, while exports make high ethanol prices impossible. When considering the effectiveness of the introduction of new technological and technical solutions, almost never paid attention to their impact on the cost of finished products. So, domestic alcoholic beverages are capable of producing high quality rectified ethanol, but the need for it both within the country and in the world is limited. The main volumes of alcohol sales on world markets are formed at the expense of bioethanol and technical ethanol (ethanol for technical needs). At the same time, prices for them are formed taking into account competition with products of the same purpose, offered by producers of other branches of the economy. Therefore, the development of the ethanol industry is possible only by changing the main directions of its use in the production of beverages for technical and transport needs and taking into account the economic results of the implementation of technological and technical solutions.Документ An improved method for determining the mass fraction of calcium carbonate in the carbonate bedrock(2021) Kos, Tatiana; Kuznietsova, Inha; Sheiko, Tamila; Khomichak, Liubomyr; Kambulova, Yuliia; Bal-Prylypko, Larysa; Vasyliv, Volodymyr; Nikolaenko, Mykola; Bondar, Nikolai; Babich, IrinaIn the article it is offered to enter in the technological audit of the lime department of sugar factory the adjusted technique of the definition of the maintenance of calcium carbonate in carbonate breed. For this purpose, a complete chemical analysis of limestone was performed, which includes determination of moisture content, impurities insoluble in hydrochloric acid, the amount of one and a half oxides of aluminum and iron, calcium carbonate (advanced method), and magnesium carbonate, calcium sulfate, alkali metal oxides, potassium, and sodium. The obtained experimental data are summarized in one table and the material balance of all components of carbonate bedrock is summarized. The proposed method made it possible to obtain objective data on the component composition of the carbonate material. This, in turn, avoids many technological problems, namely to reduce the formation of melts in the lime kiln, improve the filtration of juices, increase the ability of lime to chemically interact with water, reduce the volume of water on the juicer etc. Thus, the use of the recommended method for determining calcium carbonate (CaCO3), as part of the technological audit, will allow early adjustment of the process, which will give maximum energy and resource savings, as well as increase the level of environmental friendliness of the enterprise.
