Документ Experimental research of mass transfer in a stabilized foam layer(PC Тесhnology сеntеr, 2021) Moiseev, Viktor; Manoilo, Eugenia; Khukhryanskiy, Oleg; Repko, KalifThe object of research: mass transfer processes on a combined contact element in a column apparatus. Investigated problem: determination of the regularities of process parameters in the processing of gas-liquid systems in a foam layer, as well as to interpret the obtained experimental data. The problem of processing industrial gas flows is solved by conducting the process in an intensive mode. The main scientific results: as a result of the study, the regularities of ammonia absorption were revealed depending on the main parameters of the experiment: gas velocity in the column cross-section, ammonia concentration, free cross-section of the combined contact element, and liquid loads. The process of mass transfer in the gas phase is significantly influenced by hydrodynamic parameters – the gas velocity in the apparatus and the specific load on the liquid, which indirectly affect the height of the liquid layer on the plate and the gas content of the layer. The area of practical use of the research results: sorption processes for processing gases and liquids in technological processes, absorption of harmful substances in the treatment of gas emissions. Innovative technological product: new block poppet-nozzle contact device that operates in a stabilized hydrodynamic mode; new ball-shaped weighted nozzle for three-phase foam layer. Scope of application the innovative technological product: technological processes in the treatment of gas emissions or technological gases.Документ Foam layered apparatus with foam stabilization(Lviv Polytechnic National University, 2019) Liaposhchenko, А.; Khukhryanskiy, О.; Moiseev, V.; Manoilo, Е.In work were studied the expanded models of foaming apparatuses with gratings, made of tubes of different diameters. The questions of intensification of foam devices with the use of coarsegrating lattices are considered. The possibility of deep cleaning and practically complete cleaning of gases from ammonia and fluoride compounds with their separate absorption is noted.Документ Reducing of gas emissions from the production of calcinated soda ash(Lviv Polytechnic Publishing House, 2018) Moiseev, V.; Manoilo, Е.; Hrubnik, A.; Liaposhchenko, А.; Khukhryanskiy, О.Reducing the negative impact on the environment of the production of soda ash is achieved by reducing the formation of gas and dust emissions, as well as their deeper cleaning. The problem of cleaning gas emissions from the production of soda ash is solved by using hollow vortex devices. The advantages of multi-stage vortex-type apparatuses for cleaning large volumes of industrial gas emissions are noted.Документ Intensification of Foam Layered Apparatus by Foam Stabilization(Sumy State University, 2018) Liaposhchenko, O.; Khukhryanskiy, O.; Moiseev, V.; Ochowiak, M.; Manoilo, E.In this work the expanded models are studied for foaming apparatuses with gratings made of tubes for different diameters. The problem of intensification of foam devices using coarse-grating lattices is considered. The possibility of deep cleaning and practically complete cleaning of gases from ammonia and fluoride compounds with their separate absorption is noted. The series of experimental dependencies for the main parameters of the process are given. The possibility of effective mass-exchange processes in an intensive foam layer on counter-current coarsegrating lattices is confirmed. The controversial requirements for equipment have been given despite the large number of existing machines for mass transfer processes, as well as the development of new high-intensity and efficient equipment for environmental technologies in many industries is considered.Документ Очищення та утилізація газових викидів виробництва кальцинованої соди(НТУ "ХПІ", 2017) Грубнік, Аліна Олегівна; Манойло, Євгенія Володимирівна; Моїсєєв, Віктор Федорович; Васильєв, Михайло Ілліч; Давидов, Денис ВалерійовичСтаття присвячена питанню зниження негативного впливу на навколишнє природне середовище виробництва кальцинованої соди, яке досягається за рахунок скорочення утворення кількості газових і пилових викидів, а також їх більш глибокого очищення. Проблема очищення газових викидів виробництва кальцинованої соди вирішується за рахунок використання порожнистих вихрових апаратів, наведено їх порівняння з діючими апаратами. Відзначені переваги багатоступеневих апаратів вихрового типу при очищенні великих обсягів промислових газових викидів.
