At the current stage of development, transition to a circular economy is single option achieve sustainable mining. Purpose was identify direction for mining tailings usage based on waste management. The novelty author's approach lies in regulation mechanical treatment slag optimize backfill composition. methodology involved study (slag) obtained from major (eight) metallurgical plants Russia. For mathematical processing primary data, smoothing and deterministic three-dimensional interpolation methods were used. As result, first time it has been established that ultimate uniaxial compressive strength after increases by logarithmic laws. curing 10 days 90 (with addition Ca or Si) 21 % (7 23 %). possibility completely replacing traditional cement binder with composite proven. It use activation (both chemical) makes possible increase characteristics samples their curing. principle organizing production implemented, which provides intermediate products (blast furnace granulated slag), previously classified as technogenic waste, closed cycle. introduction this will eliminate (minimize) formation man-made waste. scientific merit slag) allows implementation

Development of the Separation Column’s Temperature Field Monitoring System

Energies, Год журнала: 2024, Номер 17(20), С. 5175 - 5175

Опубликована: Окт. 17, 2024

Oil is one of the main resources used by all countries in world. The ever-growing demand for oil and products forces companies to increase production refining. In order net profit, producing are constantly upgrading equipment, improving technologies, preparing further processing. When considering elements primary refining difficult conditions, such as hard-to-reach or remote locations, developers face strict limitations energy dimensions. Therefore, use traditional systems causes a number difficulties, significantly reducing efficiency. this study, authors solve problem characteristics separation process. their work, analyzed columns distillation, identified shortcomings technological process, searched solutions. Having lack technical solutions monitoring state temperature field column, developed own hardware–software complex column (RF patents No. 2020665473, 2021662752 were received). was tested successfully implemented into production. study provides an assessment economic efficiency implementation year forecast effect 10 years.

Increasing the Sustainability of the Strategic Development of Oil Producing Companies in Mexico

Resources, Год журнала: 2024, Номер 13(8), С. 108 - 108

Опубликована: Авг. 1, 2024

In the oil industry, there is a gap between goals of sustainable development, implementation projects and its specific consequences. Oil are implemented in isolation from other variables, have an insufficiently targeted impact on territory often negative environment. The purpose study to improve efficiency producing companies increase their contribution development country’s economy as whole. methodology used this article based concept systemic integrated approaches, sub-potentials modeling business processes circular economy. results include methodological approach formation effective model for companies. We propose select companies, taking into account economic, environmental factors, most promising prospects Mexico. significance that proposed makes it possible sustainability integrate task increasing operation territory. novelty lies application calculation critical indicator values Mexico prevent transition functioning threat containment during project implementation.

Russia’s Arctic policy focuses on making large-scale progress in the Arctic’s social and economic domains, including development of local natural resources Northern Sea Route establishment high-tech centers that can create global value chains. One primary challenges threats to sustainable Russian regions is mismatch between regional higher education systems needs economy. The risks are significantly exacerbated by transformation advent Fourth Industrial Revolution. Therefore, when considering prospects for innovation-driven economy, a critical issue accumulation highly educated human capital, where plays key role. article explores issues surrounding formation capital from perspective growth. goal this work empirically test theory increasing returns investments education. premise has constant therefore grow indefinitely. This made it possible put forward hypothesis better population’s access education, bigger and, accordingly, growth gross output per capita. An empirical assessment was conducted check model influence university enrollment rates results indicated high coefficient determination regression time series studied indicators.

The research objective of this article is to develop an optimal model for a human security system in the Arctic Zone Russian Federation (AZRF). This topic has gained particular relevance as focus exploration shifted include interests, needs, concerns, and threats security. Despite shift, concept not yet been incorporated into strategic documents that outline development priorities AZRF, nor practical policies at federal, regional, or municipal levels. study employs qualitative methods systems modeling elements quantitative analysis create index AZRF. novelty lies its existing identifying key management mechanism, their interrelationships, challenges mechanism's functioning. Based on analysis, specific recommendations are proposed optimize structure public administration area improve effectiveness interactions between government structures, businesses, civil society organizations (including indigenous peoples' organizations) operating Additionally, develops set indicators describing various aspects region. In accordance with UN recommendations, these classified seven groups, covering economic, food, health, environmental, personal, cultural, linguistic, political Using indicators, proposes Arctic. will enable monitoring trends AZRF inform adjustments policy area.

The relevance of assessing the applicability intelligent wells using autonomous inflow control devices lies in active development relevant sector oil and gas industry limited understanding economic efficiency wells. use allows for a change composition flow to well, thus contributing delaying breakthrough undesirable formation fluids, but at same time, such an effect affects dynamics fluid production, which undoubtedly has huge impact on project. analysis scientific publications topic “intelligent well completion” as downhole production monitoring remote system shown that vast majority researchers pay attention evaluation technological efficiency, ignoring aspects proposed solutions. This study considered dependence geological reservoir characteristics variant 1—intelligent horizontal (HW) completion 2—conventional open hole. Calculations levels two variants were performed created hydrodynamic model operating depletion mode. obtained results allowed us determine criteria configuration object study, establish general dependencies net discounted income well. As result this it was determined with relative conventional increases decreasing permeability drawdown pressure reaches maximum values thickness oil-saturated part about 5–6 m location wellbore 35–40% below gas–oil contact (GOC). article covers research gap evaluating HW AICD rims.
