This paper shows the oil-oxidizing ability of Micrococcus bacteria isolated from the Nakhodka Bay surface waters of the Peter the Great Gulf, the Sea of Japan. Micrococcus Bacteria are known to be the most active destructors of petroleum hydrocarbons in natural biotopes, contaminated objects. Voroshilova-Dianova liquid containing 2,5% oil or oil products was introduced into sterile penicillin bottles with 105 cells of the investigated bacteria. The ability to destruct petroleum hydrocarbons by bacteria of this genus was studied using a gravimetric method during 30 days. Destruction of oil, gasoline, fuel oil and diesel fuel was shown. Micrococcus bacteria showed a high oil-oxidizing ability and decompose 65-99,9% of oil and oil products within 30 days. Gasoline was the source of petroleum hydrocarbons with the greatest ability to utilize this genus of bacteria. The destruction of this hydrocarbons source by bacteria on days 15-20 was about 99% of the initial concentration. The lowest ability of destruction by Micrococcus bacteria was revealed for diesel fuel.

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.

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.
