Oil And Oil Products

Hydrocarbon-oxidizing microorganisms are widespread in natural ecosystems, since the ability to oxidize hydrocarbons is associated with the presence of enzymes of the oxidase group, with microorganisms using oil and oil products as the sole source of carbon and energy in the microbiological decomposition of hydrocarbons. The decomposition of oil and oil products in the soil under natural conditions is a biogeochemical process in which the functional activity of a complex of soil microorganisms that ensure the complete mineralization of oil and oil products to carbon dioxide and water is of crucial importance. The search for effective indigenous hydrocarbon-oxidizing microorganisms, the creation on their basis of a full-fledged specialized consortium of microorganisms and their introduction into the initial, cleaned environment is one of the promising methods of purification with oil pollution in the oil-producing regions of Kazakhstan. Among the new biological methods for cleaning soil from oil pollution, the most promising are the use of a consortium based on immobilized microorganisms. A correctly selected carrier capable of sorption of petroleum hydrocarbons preserves and maintains attached cells in a viable state for a long time and protects them, especially at the initial stage of introduction, from adverse environmental conditions, which increases the efficiency of oil destruction. Hydrocarbon-oxidizing microorganisms have high emulsifying activity and sorption ability for expanded clay, optimal conditions for biomass accumulation are: temperature 28-30 °С, pH = 7 and 9. It is recommended to use a consortium of oil-degrading microorganisms based on the native strains of cultures Bacillus firmus S20, Bacillus subtilis PR28, Micrococcus roseus UD6-4, Micrococcus varians PR69 to clean the soils contaminated with oil and oil products in the Zhanatalap field in the Atyrau region. It should be noted that after 8 months at the Zhanatalap field in the Atyrau region, oil destruction amounted to 94.3% in the variant with the introduction of immobilized microorganisms on zeolite and expanded clay. The results of the research are the basis for further development of technology for the restoration of oil-contaminated soils in arid conditions of Kazakhstan.

Laboratory Setup

Purpose: The aim of this work is the operational electrophysical method of the control for contamination and purification of soil from oil products and the identification of changes in the soil properties in electrochemical processing to determine rational modes of processing.Methods: Investigations are performed on the laboratory setup including the two -electrode scheme of electric treatment of the artificially polluted soil .The setup is equipped with a system of micro sensors of specific electrical resistance. Traditional laboratory tests are used to determine the physical and mechanical properties of soils. The possibility of control for soil purification by electrochemical method using a system of continuous operational geophysical monitoring is considered.Results: Changes in the physical properties of contaminated soils are experimentally confirmed when exposed to the electric current. A physical model is created for coagulation of oil products in pores during the electrical processing. It increases the amount of sand and clay components with changes in the electrical resistance of soil. The physical processes in the clean and polluted soil are compared. It is shown that when electric current passes through contaminated soils, oil products in pores transfer to a solid, less toxic state, which leads to a change in the specific electrical soil resistance throughout the zone processed. This pattern should be used to control soil decontamination.

The model of ecological rationing of oil-polluted soils is substantiated according to the function of providing the soil with conditions for biological activity according to separate biological indicators sensitive to oil products, in particular, catalase activity and survival of pot worms. Petroleum products were rationed in different types of soils of the Sakhalin region: high-moor peat bog; humus podzolic surface-glue; alluvial meadow acidic; brown forest acid podzolic in model series with different levels of pollution. The establishment of a standard value at which the functioning of the studied soils changes, was carried out according to the criterion of changing the values of selected biological parameters corresponding to the change in the rate of soil functioning with increasing oil concentration according to the dose-effect model. For the standard of soil quality for petroleum products in the regions of oil production, the value of petroleum products was used, leading to a significant deviation of the values of biological indicators from background values determined by the same biological indicators. For the permissible residual content of oil products in soils, in which the soil maintains stable functioning, performs environmental functions, a 30% change in the functioning of the soil from the background analogue according to the studied biological indicators was taken. Calculations on the rationing of oil content in soils can be performed using the non-linear regression model described by the logistic curve.

AbstractThe results of field, analytical, and experimental research at a number of production facilities reflect the properties of oil-contaminated soils in 3 landscapes: the permafrost treeless Arctic ecosystem, boreal forest, and temperate-climate grassland-woodland ecotone. Laboratory studies have revealed the concentrations of petroleum hydrocarbons in soils, ranging from medium levels of 2000–3000 mg/kg to critical figures over 5000 mg/kg, being 2–25 times higher than the permissible content of oil products in soils. The experimentally applied thermal effects for the oil products desorption from the soil allowed finding an optimal regime: the treatment temperature from 25 to 250 °C reduces the concentrations to an acceptable value. The conditions are environmentally sound, given that the complete combustion point of humates is ca. 450 °C. The outcomes suggest the eco-friendly solution for soil remediation, preserving the soil fertility in fragile cold environments and in more resilient temperate climates, where revitalized brownfields are essential for food production.

The results of experimental studies to assess the effect of humic preparations on the processes of microbiological remediation of soils contaminated with oil products of various fractions (gasoline, diesel fuel, fuel oil) is presented. The object of the study was humic preparations, different in their state of aggregation, sources and isolation technology. The evaluation criterion was the degree of degradation of oil products in contaminated soils with the combined use of industrial microbiological destructors and humic preparations. It was found that the introduction of humic preparations into the soil contaminated with oil products stimulates the processes of their microbiological remediation. Thus, the degree of degradation of oil products under the influence of humic preparations increases by 10–70 %, depending on the properties of the oil products themselves, as well as on the characteristics of the introduced preparations.

Arctic Conditions

Arctic zone of the Russian Federation occupies a large area of the country and it differs from other regions with special climatic conditions. In winter air temperature can be lowered to 70°C below zero in the Arctic, and almost all the territory is located in the permafrost zone. The main potential sources of emergency conditions resulted in oil products used as finished raw materials, fuel and lubricants which will inevitably fall into the soil, are operated machinery and equipment for the hydrocarbons extraction and transportation. Weak self-recovery potential of soils in a short growing season and low temperatures involves the development and use of adapted to arctic conditions technologies for rapid overcoming of accidental oil spills consequences. We propose adapted to arctic conditions technology for rapid consequences elimination of accidents involving oil spills. Decontamination technology of soils polluted with oil products is based on the encapsulation of the pollutant (reagent encapsulation technology) with an alkaline reagent based on calcium. We used as a reagent powdered building quick lime; it is carbonate rock calcine or a mixture of this product with mineral additives (calcium oxide). The main advantage of the reagent encapsulation technology is decontamination efficiency of contaminated soils compared to traditional technologies of decontamination. One more important factor is low market value of lime as compared to other reagents, biological substances and solvents for the oil products extraction. We describe the basic steps of the reagent encapsulation technology in decontamination of soils contaminated with oil products. If we use exotherm process energy of chemical decontamination of soils contaminated with oil products, in combination with a forced feed of carbon dioxide to decontamination zone; then at the stage of coat formation from calcium carbonate on the surface of the pollutant it allows to complete decontamination of soils contaminated with oil products using the reagent encapsulation technology in extreme Arctic natural climatic conditions. We describe the principle of equipment operation allowing to carry out decontamination of soils contaminated with oil products using reagent encapsulation technology in Arctic climatic conditions. Encapsulated material obtained as a result of decontamination of soils contaminated with oil products, is resistant to natural and anthropogenic factors, such as moisture, temperature changes, acid rain and high pressure. We present the results of experimental studies for determining the optimal amount of the reagent required for the efficient completion of the decontamination of snow contaminated with motor oil, and soils contaminated with oil products depending on the degree of contamination and the type of pollutant. Our studies confirm that the reagent encapsulation technology showed good performance in severe climatic conditions and they are suitable for decontamination of soils and snow contaminated with gasoline, diesel fuel and engine oil.

The paper analyzes the consequences of the abolition of the export duty on oil and oil products as a necessary step to stimulate energy efficiency of Russia’s economy and eliminate underdevelopment provoked by a long-term subsidizing of inefficient oil refining sector in Russia. The calculation results have shown that even taking into account several deviations from the planned scenarios of changing the parameters of tax regulation of the oil industry in 2014— 2019, the tax maneuver brought over 3.5 trillion rubles (in 2019 — 148 billion rubles) to the state budget in 2014—2017, mainly due to an increase in the base mineral extraction tax rate, and contributed to an increase in the depth of oil refining from 72% to 85%. In addition, the article analyzes possible risks associated with the current plan for reforming the taxation of the industry until 2024 and proposes an alternative that could level some of them. A comparative analysis of the effects of the tax maneuver under the current reform plan and the alternative variant suggests that the latter will allow to achieve a greater total budgetary effect in four years, reduce the cost of subsidizing domestic oil refining, increase the efficiency of Russian vertically integrated oil companies, and reduce the growth rate of oil products prices in the retail market.
