Neural Network Technologies In The Automatical Control Systems Of Absorption Process For Pureficating Natural Gas, Abdishukurov Maqsudovich Shavkat Mr, Xuecheng Li Li Xuecheng Mr

Technical science and innovation

Analysis of methods and algorithms for synthesizing adaptive control systems for technological processes based on the neural network approach is carried out in this search. The stages of mathematical modeling of complex technological processes using neural network technology were considered. Additionally, an algorithm for solving the interpolation and extrapolation problem that arises in the training process a neural network to control system was proposed. At the final stage of this article, algorithms based on neural network technology are synthesized for the control system for the parameters of the technological process of natural gas purification by absorption


Modern Ir-Spectroscopic Methods For The Analysis Of Hydroxybenzene-Methanal Resin Obtained On The Basis Of 2,5-Furandion, Sherali Anvarovich Umarov, Ravshan Israilovich Ismailov Ismailov Mar 2025

Modern Ir-Spectroscopic Methods For The Analysis Of Hydroxybenzene-Methanal Resin Obtained On The Basis Of 2,5-Furandion, Sherali Anvarovich Umarov, Ravshan Israilovich Ismailov Ismailov

Technical science and innovation

The chemical changes occurring during the synthesis of hydroxybenzene-methanal resins obtained on the basis of 2,5-furandion under various ratios and temperature conditions were investigated using the IR spectroscopic method. Analysis of the compositional changes in the resin during the production of the thermoreactive resin revealed that the content of hydroxyl groups (~3300–3500 cm⁻¹) decreased, while the aldehyde groups (~1700–1750 cm⁻¹) increased; moreover, the presence of ether groups (~1050–1150 cm⁻¹) indicated that the process was successful. The synthesis of resins based on thermoreactive hydroxybenzene-methanal resins was carried out at high temperatures (70°C, 80°C, 95°C). During the identification of the functional groups …


Research Of The Influence Of Physical And Chemical Properties Of Coal On The Gasification Process Using The Example Of Angren Brown Coal, Murodjon Mamitbekovich Kavkatbekov, Rakhimzhan Pachekhanovich Babakhodzhaev Apr 2024

Research Of The Influence Of Physical And Chemical Properties Of Coal On The Gasification Process Using The Example Of Angren Brown Coal, Murodjon Mamitbekovich Kavkatbekov, Rakhimzhan Pachekhanovich Babakhodzhaev

Technical science and innovation

The influence of the properties of Angren brown on the process of layered gasification was studied. The dependence of the calorific value of the resulting gas on the quality characteristics of coal when using air as a gasifying agent has been established. Methods are shown for increasing the calorific value of gas obtained during the gasification process when using coal with different moisture content and different fractional composition. The features of technological processes in the reaction zones of a laboratory gas generator have been studied. Based on generally accepted methods, the volume fractions of flammable components, as well as the …


Clearance Of Solid Household Waste With The Reception Of Alternative Types Of Energy Carriers, Rakhmatullayev F, Turabdhanov S Nov 2020

Clearance Of Solid Household Waste With The Reception Of Alternative Types Of Energy Carriers, Rakhmatullayev F, Turabdhanov S

Technical science and innovation

The research is devoted to improving the technology of obtaining alternative types of energy carriers by applying methods of pyrolysis of unclaimed types of solid domestic wastes of biological origin, which also allow solving the tasks of improving the ecological situation in the places of formation. The practical value and relevance of this research lies in the development of advanced technology for obtaining alternative fuels. The proposed pyrolysis unit allows producing gaseous and liquid hydrocarbons in a continuous cycle. In the atmosphere of the gasifying agent (air, oxygen, water vapor, carbon dioxide or their mixture), the gasification process is primarily …
