The technological process of aluminium electrolysis is a complex scientific and technical task. This due to large number internal, external resultant factors. aim this work analyse these factors, assess them their influence on the develop comprehensive mathematical model production in Soderberg electrolyser. analyses primary basis Bayer method then Hall–Eru method. existing methods technologies for computer modelling are analysed. modern analysis thermal electromagnetic fields electrolysers considered. On an in-depth analysis, factors influencing identified. Using system identified ranked list according degree obtained. Pareto diagram, we obtain with maximum impact. A conceptual derived. Based obtained model, conducted research may be useful specialists field metallurgy processes production.

Abstract This study is devoted to improving the economic efficiency of cell, due field generated electromagnetic field’s accurate diagnostics. To solve this problem, authors had developed a hardware-software complex for includes measurement device and software package data collection analysis. On laboratory prototype aluminum electrolysis complex, was carried out on formation structure field. A number experiments have been showing degree by anode, relationship fields in inter-anode space has shown. Based results studies, conclusions were drawn about possibility diagnosing current state determining direction rotation electrolytic cell estimating life anode its burnout time.

The article considers a mathematical model of the hydrolithospheric process taking into account skin effect. A methodology for using results groundwater inflow testing to determine parameters approximating models that take effects is presented. In addition, problems modeling hydrodynamic processes random factors are considered. statistical analysis well monitoring data was carried out and an algorithm studying developed. Using obtained models, procedure solving problem selecting optimal number production wells has been Based on testing, prospects development use new aquifers can be determined.

The Arctic’s specific conditions require increased attention to natural and human capital. Therefore, implementing the principles of sustainable development concept, balancing economic, social, environmental goals is paramount importance. Mining at heart strategy for socio-economic Russia’s Arctic territories. This study’s objective topical: justify measures lifting restrictions on AZRF (the Zone Russian Federation) mining regions. authors propose a method identify regions where determines level (Komi Republic, Nenets Autonomous District, Yamalo-Nenets Yakutia, Chukotka District). multi-factor regression analysis conducted confirms hypothesis that living standards achievement social in depend income fiscal capacity levels, which makes state more responsible region’s development. prove expediency reconsidering proportions rental redistributed between budgets federal budget favor former, until migration population growth become positive reach target indicators strategies results can be used policy while elaborating

Process of grain drying is discussed by the authors, which considered one preliminary stages in technology biodiesel production. The process has a number disadvantages that affect quality and cost fuel. impossibility uniform heating maintaining required temperature with minimal energy costs most important defects deserve scientific research. authors propose method for changing system preheating raw materials, based on world experience. We carried out mathematical calculations, provided change field chamber over time, we also performed industrial experiment. Based our results determined optimal sources taking into account dimensions chamber. technical solution can be obtained Thus, uniformity will increased, large operating associated leakage oil from grains disappeared.

National energy efficiency is a key driver for the sustainable development of society. However, conditions increasing vary widely around world and depend on numerous controllable uncontrollable factors. Existing indicators assessing typically focus individual factors, neglecting complex interplay socioeconomic, environmental, technological, other factors that influence efficiency. This limitation hampers quality assessments. The goal this study to develop apply comprehensive methodological approach across different countries. utilizes factor analysis methods identify correlations between energy-efficiency study’s findings offer model enables more profound multifactorial impact experienced by national economies in various domains areas.

The most important source of human life support is water. During the development mineral water fields, unsustainable patterns production and consumption have been observed, which could lead to environmental damage deterioration quality sources. In this work, a procedure for determining modified link’s parameters, replacing static dynamic indicators hydrodynamic process, proposed. Recording parameters at different filtration coefficients along spatial coordinates allows safety aquifers be increased pressure reservoir stabilized. presented approach accuracy process used control reservoir’s increased.

Energy landscapes in Asia and other regions are currently undergoing a transformation aimed at increasing the share of clean energy sources. This article analyzes forecasts electricity demand Vietnam, examining existing constraints that necessitate shift from coal to renewable The rapid economic growth Vietnam is driving substantial surge demand, projected reach 124 thousand MW by 2030 according National Electricity Plan, positioning second Southeast Asia. poses significant challenge national security, given impracticality effective mining country imperative develop Anticipating changes Vietnam’s mix 2050, this study foresees reduction dependence on production. Government investment green funds such as JETP strategically directed towards sources, including solar, wind, biomass, hydrogen energy, efficient storage technologies. Consequently, research substantiates viability an transition Vietnam. presents assessment rate replacing with taking into consideration various scenarios for development, consumption growth, utilization

China is endowed with a large quantity of residual coal resources that require upward mining. The stability interburden strata structures and accurate determination are crucial for safe Therefore, we established mechanical model disturbed voussoir beam in was solved, analysis instability mechanism were conducted. Based on this model, new method determining the feasibility mining proposed applied to seam No. 7 Baijiazhuang Coal Mine. A physical simulation experiment numerical conducted validate method. Through research, it found had two mechanisms: rotation sliding instability. When disturbance load crossed critical block structures, most likely experience acted entirely block, more occur. result determination, performed using method, showed there no or 7, indicating could be mined upward. This consistent determinations statistical “three-zone” balanced surrounding rock Physical simulations revealed caused subsidence, rotation, separation compaction but remained stable. results indicate have accuracy applicability, being able guide practical
