Документ Інтенсифікація процесу сушіння молока(Scientific Publishing Center "Sci-conf.com.ua", 2023) Нечипоренко, Дмитро Ігорович; Єлізаров, Андрій ПетровичДокумент Influence of structural descriptions of underbody of bicarbonate columns on duration of period of their operation and ecologization of process(РС Tесhnology Cеntеr, 2021) Porokhnia, Mykola; Shestopalov, Oleksii; Bukhkalo, Svitlana; Novozhylova, TetianaObject of research: optimization of the operation period of bicarbonate columns by optimizing their design features. Investigated problem: increasing the efficiency, environmental friendliness and dura tion of the bicarbonate columns by optimizing the design of the sludge discharge unit. Main scientific results: the article analyzes the main design features of bicarbonate columns for the production of purified sodium bicarbonate. A relationship has been es tablished between the design of the apparatus, the intensity of mixing and the duration of the apparatus operation without stopping for washing. On the basis of the existing prob lems, laboratory and industrial experiments were carried out at one of the soda plants, aimed at increasing the efficiency of operation of the bicarbonate columns of the purified sodium bicarbonate shop. So, due to the modernization of the design of the sludge un loading unit and the identification of the optimal amount and month of the location of the mesh trays, an increase of 1.5-2 times in the duration of operation of the columns without stopping for washing was achieved. This contributed to an increase in plant productivity and environmental friendliness of the process due to a decrease in the amount of liquid waste generated during the washing of the column equipment. Area of practical use of the research results: enterprises for the production of purified sodium bicarbonate of food and pharmaceutical quality. Innovative technological product: design solutions for bicarbonate columns and the technology of carbonization of soda-bicarbonate solution for the production of purified sodium bicarbonate. Scope of application of the innovative technological product: soda production, food and pharmaceutical industries.Документ Інтенсифікація процесу сушіння з використанням слабких електроімпульсних впливів(Донецький національний технічний університет, 2023) Нечипоренко, Дмитро Ігорович; Сакун, А.; Таран, С.; Лазаренко, М.Документ Identification of the oxidation and hydrolysis products content influence on the rapeseed oil oxidation induction period(Technology center PC, 2024) Stankevych, Serhii; Gorbunov, Kostiantyn; Zabrodina, Inna; Popov, Mykola; Kalyna, Viktoriia; Novozhylova, Tetiana; Falalieieva, Tetiana; Ovsiannikova, Tetiana; Ponomarova, Maryna; Zolotarov, AndriiThe object of the study is the dependence of the induction period of rapeseed oil on the content of oxidation and hydrolysis products. A feature of the work is determining the approximation dependence of the induction period of accelerated oxidation of refined rapeseed oil on the content of primary oxidation products and free fatty acids. This is useful when predicting the shelf life of refined rapeseed oil. It was determined that both factors negatively affect the oxidation stability of refined rapeseed oil. An increase in the peroxide value decreases the induction period of model oil samples by 32.8512 units for each additional mmol ½ O/kg. In turn, increasing the acid value of oil samples reduces the induction period by 19.8424 units for each additional mg KOH/g. Different oxidation dynamics of model samples of refined rapeseed oil with tocopherol were revealed, depending on the concentration of primary oxidation and hydrolysis products. The obtained data are explained by the fact that the primary lipid oxidation products are unstable and quickly decompose to form free radicals. These radicals initiate further lipid oxidation, resulting in reduced oil quality. In addition, free fatty acids are more reactive than triglycerides and are more easily oxidized. A feature of the obtained results is the possibility of modeling processes that affect the oxidation stability of refined rapeseed oil. From a practical point of view, the research results allow initiating measures to maintain the safety of oil-containing food products based on refined rapeseed oil. An applied aspect of using the scientific results is the possibility of rationalizing the storage conditions of refined rapeseed oil to maximize its shelf life and increase competitiveness.Документ Determination of the influence of hemp oil-based emulsion systems composition on the oxidation products content during storage(Technology center PC, 2024) Kunitsia, Ekaterina; Popov, Mykola; Gontar, Tatiana; Stankevych, Serhii; Zabrodina, Inna; Stepankova, Galyna; Zolotukhina, Olena; Filenko, Olesia; Novozhylova, Tetiana; Nechyporenko, DmytroThe object of the study is the content of antioxidants and the induction period of accelerated oxidation under simulated conditions of the lipid component of the emulsion system. The way to solve the problem of developing compositions of oxidation-stable emulsion systems based on nutritionally valuable oils, in particular hemp oil, by adding natural physiologically active antioxidants is considered. The research is relevant in the context of finding effective storage methods and extending the shelf life of products using hemp oil. The feature of the work lies in determining the influence of the composition of emulsion systems based on hemp oil on chemical oxidation during storage. The content of stabilizers in the hemp oil emulsion system (lecithin – 0.8...1.0 %; xanthan gum – 0.0...0.1 %) is proposed, which is effective in the inhibition of oxidative spoilage. The content range of β-carotene (0.012 %) in model emulsion systems is outlined, the addition of which increases the induction period of accelerated lipid oxidation by 1.58...2.08 times. The peroxide value of the lipid component of the emulsion system during storage at different temperature conditions (0...15 °C) and during different storage periods (15...60 days) was studied. The results of the study confirm the significant influence of the composition of emulsion systems on the chemical oxidation of the lipid component, which is important for ensuring the quality and stability of food, pharmaceutical and cosmetic products. An applied aspect of the obtained scientific result is the possibility of modeling the composition of emulsion systems based on valuable hemp oil depending on the ratio of polyfunctional antioxidants of the oil component.Документ Studies of the physical, operational and optical-spectral characteristics of the highly transparent toluenesulfonamide and benzguanamineformaldehyde polymers(Kamianets-Podіlskyi National Ivan Ohiienko University, 2020) Lebedev, Vladimir Vladimirovich; Tykhomyrova, Tetiana SergiivnaДокумент The results of surface wastewater treatment of a machine-building enterprise from petroleum product contamination(National Institute of Research and Development in Mechatronics and Measurement Technique, 2024) Bosiuk, Alona; Shkop, Andrii; Kulinich, Serhii; Loboiko, Viacheslav; Sakun, Antonina; Shestopalov, Oleksii; Filenko, OlesyaPetroleum pollution is an urgent and serious problem that has a negative impact on environmental safety and the state of the environment. Petroleum products that enter water resources cause a number of negative consequences, including water and soil pollution, reduced quality of natural ecosystems, as well as threats to biodiversity and human health. The purpose of this study is to assess the effectiveness of methods for treating surface wastewater of a machine-building enterprise from poll ution by petroleum products. In the course of the work, the results of cleaning the surface wastewater of the machine-building enterprise from pollution by petroleum products, samples of which were taken from the rainwater intake well at different depths – 30, 60 and 80 cm. A purification scheme has been developed and optimized, which includes the introduction of Al2(SO4)3 coagulant and A-19 flocculant into wastewater. Purification efficiency is achieved at about 95% at optimal reagent doses of 60-80 mg/L coagulant and 2-2.5 mg/L flocculant. The advantage of the conducted studies is the possibility of using the obtained data and methods for the analysis of wastewater with a similar composition of contaminants. It has been experimentally established that the simultaneous administration of reagents or the use of only one of them has lower efficiency and leads to insufficient purification of water from petroleum products. Neutralization of ion resistance contributes to the formation of coagulation structures, and to increase them it is recommended to use a flocculant to form and increase the size of aggregates. The results of the studies confirmed the prospect of using flotation to further separate the emerging petroleum flocculi, which allows to reduce the amount of reagents used and improve the efficiency of water treatment. The obtained data are important for practical application in the field of wastewater treatment from petroleum products at machine-building enterprises, contributing to the improvement of the quality of water resources and compliance with environmental safety requirements.Документ Екологічна небезпека стічних вод нафтопереробних заводів(ДВНЗ "ДонНТУ", 2024) Забіяка, Наталія Анатоліївна; Іваніна, Софія Андріївна; Гуменюк, Катерина ОлександрівнаДокумент Застосування інтенсивних анаеробних технологій для очищення виробничих стічних вод(ДВНЗ "ДонНТУ", 2024) Місик, Ярина Тарасівна; Зінченко, Марія ГеоргіївнаДокумент Визначення статичних метрологічних характеристик трансформаторного електромагнітного перетворювача ТЕП зі зразком слабких електролітичних рідин(ДВНЗ "ДонНТУ", 2024) Себко, Вадим Вадимович; Забіяка, Наталія Анатоліївна; Костенко, Єлизавета Сергіївна; Гуменюк, Катерина Олександрівна
