Features of the stages of heterogeneous catalytic processes under the influence of microwave radiation
Authors: Daminev R R 
Published: September 2020

Abstract
Use of microwave electromagnetic radiation as an acting factor allows to have a significant influence on such processes as heating, phase transitions (melting, evaporation, drying), some stages of heterogeneous catalytic reactions. Consider the external task of diffusion kinetics of the process when using microwave radiation. For this purpose the investigated process is carried out in a flow reactor filled with grains of a solid catalyst, on the surface of which a catalytic reaction takes place. Let us imagine that the gas stream consists of a core, in which complete mixing takes place, and immobility of diffusion film of gas with thickness, through which diffusion to external surface of catalyst grains takes place. The concentration of reactant gas in the core of the stream is kept constant. Its concentration at the catalyst surface is lower due to the reaction; This difference results in a diffusion flow of reactant to the surface.

Published: September 2020

Abstract
A detailed local, narrowly directed impact of industrial premises emission generators on air pollution in the metalwork and welding division sectors of Voronezh Aircraft Production Association (Voronezh joint-stock aircraft manufacturing company) has been carried out. It has been found that the greatest contribution to the overall background of the polluting components accumulation in quantitative terms is made by 2 sites: sandblasting and gas welding, which are distinguished by a greater technogenic load. It has been noted that the sector of Ti plasma cutting and alloys based on it, which has potential equipment according to the work regulations, is distinguished by the variety of components allocated. The quantitative assessment of gross and maximum one-time emissions in the sectors of the locksmith and welding division of basic polluting components has been implemented. A boundary with the permissible concentration NO2 value has been fixed in the gas welding sector and it is desirable to update the working zone air cleaning systems. We assume that there is a need for modernization and that an increased amount of polluting components emissions in the working zone is possible due to the existing technological regulations and equipment that requires modernization.

Published: September 2020

Abstract
Adapting agroecosystems to the specific natural conditions of the region, as well as to the levels of man-made load on agrocenoses, is a priority task for reproducing the necessary level of soil fertility, ensuring the environmental safety of arable soils. The results of monitoring indicators of microbiological activity of chernozome leached in agrocenoses of Krasnoyarsk forest-steppe are presented. The number of ecological-trophic groups of microorganisms and the activity of oxidative and hydrolytic soil enzymes were investigated. The results of the biological assessment of the soil condition of the rhizosphere of agricultural plants may be the basis for rationing the level of anthropogenic impact on agroecosystems in the region. An increase in the activity of the catalase enzyme compared to the soil of the alfalfa rhizosphere has been established in chernozem samples in wheat and barley crops. The activity of hydrolytic protease and invertase enzymes also increased in these samples. A study of the activity of catalase and protease enzymes is recommended for environmental monitoring and control of soil conditions in crops (especially wheat and barley).

Abstract
The results of monitoring the number and structure of soil algoflora of chernozem leached in crops of forest-steppe zone of Siberia are presented. The taxonomic and ecological structure of the algoflora of the chernozem of the leached forest-steppe zone of the Krasnoyarsk Territory has been established. The presence of certain types of cyanobacteria and algae in the soil is a sign of soil fertility, and their accumulation of organic substances leads to the productivity of agrocenoses. A study of the reactions of soil algocenosis to chemical pollution of agroecosystems allows us to establish the level of their adaptation to the action of stress aggressive factors. The ecological structure of the algoflora of leached chernozem is represented by edaphophilic species, which form the basis of generic diversity. In the chernozem selected under barley, cyanobacteria dominated, capable of forming mucous covers resistant to the effects of toxins. In alfalfa crops, the most intense microscopic sprawls of soil algae were noted.

Published: September 2020

Abstract
Dynamics of acoustic signal passing through a bubble screen is investigated. The case when the gas inside the methane bubbles is in hydrate formation conditions is considered. Influence of the hydrate formation process, the initial radius of bubbles and the gas content on the value of the attenuation coefficient and the phase velocity of wave propagating through the deep-sea bubble screen have been studied. Coefficients of reflection and passage of sound waves are obtained at boundaries separating areas of single-phase and two-phase zones. It has been found that the hydrate formation process increases the wave attenuation coefficient by more than two orders of magnitude in the low frequency area (less than 1 kHz).
Application of polyurethane, rubber and aluminum as materials for the production of the dome separator
Authors: Chiglintseva A S , Nasyrov A A , Chiglintsev I A 
Published: September 2020

Abstract
The paper describes the use of the installation of the dome-separator, which is a huge tank, cylindrical in shape and open from the bottom. The installation height reaches several tens of meters and a radius of several meters. Such a design can be made of elastic (such as polyurethane, rubber) or hard (duralumin) materials. The dome-separator can be used to eliminate the breakthroughs of gas and oil wells at great depths (more than 500 meters), when blocking the well is a difficult event. Sufficiently large dimensions of the installation are needed so that the mixture entering it can be separated into gas and oil phases for selective selection. Also, the dome-separator can be used as a method of extraction. The manufacture of such a structure from elastic materials contributes to an easier way to transport the dome-separator to the place of operation. The mathematical modeling of such an installation showed that the manufacture of a rubber dome-separator contributes to more efficient heat storage inside the structure, which has a beneficial effect on the decomposition of hydrate, which can be formed under operating conditions.

Published: September 2020

Abstract
Contamination of soil by petroleum products is a major environmental issue in the subjects of the Russian Federation that occurs from human activities. The most recent example of such contamination is the oil spill in the north of the Krasnoyarsk region. The purpose of the research is to identify environmental impacts of anthropogenic contamination of soils in the Samara region by petroleum products. The paper provides an assessment of contamination of soils by petroleum products and an analysis of petroleum products content in background areas and long-term observation plots, which is the result of an impact contamination of soils. From 2014 to 2018, eight sources of impact pollution were surveyed. Of these, two – Chapaevsk (2014) and Novokuybyshevsk (2015) – resulted in moderately hazardous contamination of soils, one – Podbelsk (2017) – in moderate contamination of soils, three – Granniy (2015), Syzran and Tolyatti (2018) – in contamination exceeding increased background levels. Pollution of soils of long-term observation plots occurred only in 2014 (20 times above the background level). Analysis of soil samples taken from background areas revealed that the content of petroleum products in soil was 1.1-3.0 times above the background level. During the study period, the petroleum products content in soil changed from 7 to 1488 mg/kg. The area of remediated lands ranged from 1524.2 ha in 2015 to 735 ha in 2018. The total area value was 5650.9 ha.

Investigation of the influence of medium and microwave radiation parameters on the dynamics of decomposition of gas hydrate
Authors: Davletshina M R , Stolpovsky M V , Chiglintseva A S , Gimaltdinov I K 
Published: September 2020

Abstract
The paper considers the problem of dissociation of methane gas hydrate saturating a porous medium of finite extent under the action of an external radiation source. The mathematical model includes the equations of continuity, heat inflow, and Darcy’s law, and is supplemented by the conditions of mass and heat balance on the discontinuity surface. In this case, we consider the case when the left boundary of a porous system is impervious to gas and heat flows, and the power of the source depends inversely on the coordinate of the phase transition front. Based on a computational algorithm developed using the method of catching the front in the grid node, the influence of the initial parameters of the reservoir on the maximum temperatures and pressures implemented in the system is studied. The influence of the power of the radiation source and the volume content of gas hydrate in the system on the intensity of its decomposition is also considered.

Abstract
The paper presents a mathematical model of dissociation of methane hydrate under thermal influence on a porous layer. The problem of influence of a heat source (hot liquid) on a porous layer of finite length initially saturated with methane hydrate is considered. Temperature distributions in the system at different times are constructed. The influence of the heat source temperature on the character of the phase transition boundary motion is investigated. A technological scheme is proposed, and on its basis a mathematical model is constructed that describes heating and simultaneous gas extraction into a combined well consisting of two coaxial pipes. The efficiency of the proposed method of gas production is analyzed.
