Objectives. This study aims to establish the available porosity of a sorbent based on carbonized rice husk and investigate its sorption properties for oil and oil products.Methods. A rice-husk-based sorbent carbonized at 400°С for 30 min was selected as the subject. The porosity of this sorbent is analyzed with the help of mercury porosimeters, the Pascal 140 EVO and Pascal 240 EVO. The sorption properties of the sorbent are also studied when cleaning water containing oil and oil products.Results. The test sample is a bulk porous material with a pore volume of 0.015 cm/g; porosity higher than 15% was found, and the pore size distribution is shown. Studies were conducted on the sorption of oil and oil products as well as the possibility of using the aforementioned sorbent as a filtering material in the purification of water containing oil products. We investigated the sorption processes under dynamic and static conditions. The methodology for measuring the porous structure of solid materials on the mercury porosimeter, Pascal 140 EVO, was examined. The texture characteristics of the sorbent’s porous structure were determined, which is primarily the total volume of pores, the values of the specific surface area, and the volume of the microspores and mesopores.Conclusions. The materials studied can be used as sorbents with a developed porous structure for purification of water with dissolved and emulsified petroleum products.

The purpose of the article is to study the market of oil and oil products in Ukraine, its role in the functioning of agriculture and identify ways to improve. Research methods. Methods used: system analysis and generalization (to study and generalize the energy dependence of Ukraine); statistical (to display the situation on the oil and oil products market in quantitative terms through a system of absolute and relative indicators); analysis of the series of dynamics, structural shifts (to analyze and identify trends in the indicators of the oil and oil products market); comparison (comparison of economic indicators); graphic (visual display of research results in the form of graphs). Research results. The essence and features of the Ukrainian market are revealed, a statistical analysis of trends in the development of the oil and oil products market is carried out, factors influencing the trend of the domestic market are identified and the mechanism of their interaction is clarified. The assessment of the current level of oil independence of Ukraine is carried out. Scientific novelty. The necessity of state support in terms of restoring the competitiveness of the domestic oil refining industry, diversifying the supply of petroleum products to the Ukrainian market and maintaining the share of domestically produced petroleum products at the level of 50% of the consumption volume, as well as reducing the share of other suppliers (importers) to 30% in the total balance has been substantiated. Practical significance. The analysis made it possible to identify destabilizing factors in the oil and oil products market, determine the need for systemic changes in the market functioning model and create conditions for increasing the competitiveness of domestic oil products in the Ukrainian market, create conditions for promoting and stimulating the development of the oil refining industry to weaken the reliability of imports of oil products.

A consortium of microorganisms were isolated from TC-1 fuel form, each member of which is capable of consistently degrade hydrocarbons’ different fractions. The 5 strains of hydrocarbon-oxidizing bacteria (PSB) were identified and isolated from TS-1 jet fuel. Their physiological and biochemical features are defined. All strains exhibit positive catalase activity. It is determined that all UOB strains, producing exogenous and endogenous surfactants, are capable to growth on media with different fraction of hydrocarbons. The study of these associations allows to create effective preparations for bioremediation in the elimination of accidental spills of oil and petroleum products.

Natural objective reasons significantly complicate the objective assessment of oil products in soils: a variety of chemical forms of the pollutants connection, the soil ability to self-healing and self-cleaning, provincial features of the soil cover, lack of objective criteria.To increase the objectivity of determining the presence of oil products in soils, it is proposed to take into account the following factors: analysis methods of soils contaminated with oil products, the chemical properties of extractants extracting oil products from soil samples, the content of soil organic carbon and nonspecific organic compounds in conditionally unpolluted and oil-polluted soils, an increase in organic carbon in soils contaminated with petroleum products, units of measurement (% or mg / kg), the soil horizonin which soil samples were taken, the presence of discrepancies in GOST standards on the standardization of pollutants of organic origin in soils, the state of modern rationing of oil and oil products in soils and the terminological aspect.

Sorbents were produced on the basis of rice husk, rubber crump and apricot stone by carbonization. They all possessed a high sorption capacity for oil and oil products. With the use of these sorbents an oil overflow was experimentally removed from the surface of the river Syrdarya (Kyzylorda). Results showed that the oil sorption capacities of carbonized rice husk, rubber crumb and apricot stone were 18, 14 and 7 g/g, respectively. The material obtained by carbonization of rice husk has very good buoyancy characteristics, high oil sorption capacity and high hydrophobicity. The effects of contact time, water temperature, amount and type of sorbents on the oil sorption capacity of the carbonized sorbents were further studied on the basis of microstructure and morphology using optical digital microscopy and scanning electron microscopy (SEM). The results of the SEM and optical microscopy studies strongly indicate that carbonization is a suitable method for improving the porous structure of the sorbents particles compared to the virgin samples. This research provides the basis for the development of a new environmental material with optimal characteristics, providing efficient sorption of oil and oil products from an aqueous medium.

AbstractExperience with using permafrost for disposal of various toxic industrialwaste products and for storage of oils and petroleum products shows that underground disposal is preferable in terms of ecology and economy. However, account must be taken of possible interaction (heat, mechanical, chemical, and physico-chemical) of the buried material with the cryogenic environment and theassociated specific processes. A study of the main types of interaction of water-soluble and water-insoluble materials with frozen soil and ice permits tentative recommendations for safe storage of these materials in the Arctic.

The problem of losses of oil products from leaks during their storage and transportation at oil supply facilities is considered. The influence of oil product leaks on the environmental situation around oil depots and gas stations is shown. A detailed overview of existing methods and tools for detecting leaks of petroleum products from storage facilities is presented. The evaluation of their effectiveness. Two methods for detecting oil leaks and devices based on them are proposed. The first device monitors the movement of liquid in the tank, the second-detects petroleum products in wastewater. The problem of recovery of petroleum vapors and environmental pollution from the release of vapors of light fractions into the atmosphere is also considered. An overview of existing methods and means of recovery of petroleum vapors is presented. Two methods and devices for capturing oil vapors and returning them to the reservoir are proposed, based on different principles: vapor absorption in the cooled oil product and vapor recovery on the principle of the Carnot cycle. It is shown that these devices can provide effective detection of oil leaks and recovery of their vapors, as well as improve the effectiveness of environmental protection at modern gas stations and tank farms.
