Analysis of the Sanitary Purification of Gas Emissions from Dust in the Lime Manufacture
(Scientific Route, 2017) Pitak, Inna V.; Briankin, Serhii S.; Pitak, Oleg Ya.; Shaporev, Valery P.
Experimental studies have been carried out to study the effect of the location of the blade vortex from the end of the flue (the flow outflow from the flue to the separation chamber) by the value Vϕmax and the determination of the optimum cross section where Vϕmax is reached, and also the study of the influence of structural changes on the purification efficiency. The dependence of this swirler on the value of the tangential velocity of the gas flow at its exit from the separator is established. The cross-sections of the flue duct in which, after the swirler, the maximum values Vϕ, Vr are reached, the features of the dust-gas flow in the studied sections are considered. Based on the studies of the hydrodynamic situation during the flow of a rotating flow in the flue after the swirler, the possibilities of agglomeration of dust particles in the investigated zones, as well as the destruction of NOx gas impurities, are analyzed. During the operation of the reconstructed vortex dust collector, qualitative indices are attained, which confirm the expediency of the conducted studies and the expediency of reconstructing the vortex apparatus. It is proved that the installation of the blade vortex enhances the purification efficiency of the dust-gas flow in a vortex dust collector and will allow for a comprehensive purification of the exhaust gases.

Стаття присвячена питанням зменшення негативного впливу на навколишнє середовище виробництва кальцинованої соди, що досягається за рахунок зменшення утворення газопилових викидів, а також їх більш глибокого очищення. Проблема очищення газових викидів від виробництва кальцинованої соди вирішена використанням порожнистих вихрових пристроїв, наведено їх порівняння з робочими апаратами. Відзначено переваги багатоступінчастих апаратів вихрового типу для очищення великих обсягів промислових газових викидів. У статті зазначено, що завдання очищення промислових газових викидів значно ускладняються їх великими обсягами, що ускладнює використання традиційного очисного обладнання. Більшість пристроїв, які зараз використовуються для очищення газів від газоподібних, рідкі та тверді домішки характеризуються низькою пропускною здатністю через малі максимально допустимі швидкості газу в апараті. Обґрунтовано необхідність використання багатоступеневих вихрових пристроїв для очищення газових викидів від аміаку та содового пилу. Відзначаються переваги апарату цієї групи – низький гідравлічний опір, високий ККД і низька енергетична та металоємність. Наведено порівняння вихрових пристроїв з іншими активними газоочисними приладами за дробовою ефективністю. Запропоновано схему очищення газових викидів від содового пилу з подальшою утилізацією. Ефективність осадження субмікронних частинок у вихровому апараті з інтенсивною фазовою взаємодією може перевищувати 95 %.

It was shown that the oxidized phosphatide increases the adhesive properties of bitumen brand BND 60/90. Oxidized phosphatide concentrate can be recommended as cost-effective alternative to expensive synthetic cationic surfactants, which are now widely used as adhesives for road bitumen. Based on the results of laboratory tests, the mathematical analysis of the obtained data was performed. Comparative graphs were plotted, and Pearson’s correlation coefficients and the approximation reliability values were calculated. It was found that the optimal composition for creating effective bituminous compositions with an increased thermo-physical and adhesive characteristics is 0.6 wt.% of oxidized phosphatide concentrate.

Defining features in the kinetics of sodium carbonate-bicarbonate solution carbonization and the quality of the resulting sodium bicarbonate crystals
(Технологический центр, 2021) Porokhnia, Mykola; Tseitlin, Musii; Bukhkalo, Svitlana; Panasenko, Vladimir; Novozhylova, Tetiana
This paper reports a study into the influence of temperature and gas consumption on the carbonization kinetics (saturation with carbon dioxide) of sodium carbonate-bicarbonate solution. The study also examined the quality and speed of crystal formation in this process. This research is predetermined by the environmental problems faced by modern enterprises that produce purified sodium bicarbonate – an insufficient degree of carbonization and, as a result, excessive air pollution with carbon dioxide, which did not participate in the reaction during the process. This study addresses these particular issues. As a result of using specialized laboratory equipment, it was found that an increase in the absorbent temperature from 79 to 85 °C leads to a decrease in the maximum degree of carbonization of the solution from 64 to 59 %. In contrast, the quality of the resulting sodium bicarbonate crystals improves but only in the range from 79 to 82 °C. With a further increase in temperature, the quality stabilizes. It is shown that the carbonization rate increases with increasing specific consumption of the absorbent (carbon dioxide) and is characterized by a negative correlation with the value of oversaturation of the absorbent in terms of NaНCO₃. The quality of sodium bicarbonate crystals decreases with increasing gas velocity. Thus, it was reasonable to assume that the established dependence of the kinetics of carbonization of Na₂CO₃ and NaНCO₃ solution on the gas velocity in the apparatus is explained by the inhibition of СО₂ absorption, which is caused by the diffusion resistance of sodium bicarbonate crystallization. To improve the quality of crystals and the productivity of carbonization by reducing the supersaturation in terms of NaНCO₃, it is recommended to introduce a seed crystal in the zone of binding of crystals in the carbonization columns.

Design of inorganic polymer composites for electromagnetic radiation absorption using potassium titanates
(Сумський державний університет, 2023) Lebedev, V. V.; Miroshnichenko, D. V.; Nyakuma, B. B.; Moiseev, V. F.; Shestopalov, O. V.; Vyrovets, S. V.
This paper investigated the synthesis of inorganic polymer composites for electromagnetic radiation absorption using potassium titanates. The selected polyamide 6 and potassium polytitanate materials contain TiО2, K2СО3, and KCl obtained by charge sintering. Results showed that modification of polyamide 6 with sintering products in the form of a fine powder of potassium polytitanate that contains different phases K2O × 2TiO2, K2O × 4TiO2, and K2O × 6TiO2 which increased their strength properties. With increased potassium titanates (PTT) synthesis, a gradual transition from di to potassium hexatitanates occurs K2O × 2TiO2 – K2O × 4TiO2 – K2O × 6TiO2. The optimal content of potassium polytitanate was over 20 % by mass. To fully ensure the reinforcing effect due to the filling of potassium polytitanate polyamide 6, it is necessary to use whiskers K2O × 6TiO2, which can be collected by the additional crystallization of the amorphous charge sintering product. By designing experimental statistical mathematical models in equal regressions, mathematical optimization of inorganic polymer composites for electromagnetic radiation absorption using PTT was carried out.

Об’єктом дослідження були процеси тепломасообміну в колонному теплообміннику з безпосереднім контактом фаз. Досліджувана проблема пов’язана з необхідністю визначення оцінок кінетичних характеристик теплообміну при концентруванні розчинів у контактному теплообміннику, оснащеному двопоточними тарілками. Зокрема, передбачалося, що визначення впливу швидкості газу в апаратові і щільності зрошення тарілок рідиною, а також геометрії тарілок, на кінетичні коефіцієнти дасть змогу виявити закономірності теплообміну і масообміну між рідиною і контактуючим з нею повітрям в колонному апарату. Визначено, що для збільшення інтенсивності масообміну в газі та теплообміну в рідині необхідно збільшувати значення швидкості газу та щільності зрошення. Тоді швидкість газу та щільність зрошення приблизно однаково впливають на інтенсивність масообміну в газі та теплообміну в рідині. При дослідженні впливу геометрії тарілки на кінетичні коефіцієнти тепловіддачі в рідині та масообміну в газі встановлено, що величина частки вільного перерізу тарілки має вирішальний вплив на значення розглянутих кінетичних коефіцієнтів. Отримано узагальнене рівняння, яке дає змогу не тільки розрахувати коефіцієнт передачі ентальпії при взаємодії розчину хлориду натрію з повітрям, а й визначити лімітуючу стадію цього процесу. Отримані результати можуть бути використані в розробці установки концентрування гарячого розчину хлориду натрію випаровуванням води при продуванні повітрям в контактному теплообміннику. Це може дати змогу отримання кристалічного хлориду натрію з використанням вторинних енергоресурсів та інших нетрадиційних джерел теплової енергії.
