    Opis:
    Georgia, deprived of its own hydrocarbon resources, relies exclusively on the import. It has abstained from purchasing those from the Russian Federation for political reasons, which, combined with the lack of LNG terminal infrastructure, has led to the factual monopolization of crude oil and natural gas supplies from Azerbaijan. For geopolitical reasons, Georgia remains the only export route for Azerbaijan for these resources. Easy access to those resources due to its position as a transit state has an impact on the tempo of energy transformation in Georgia. On the one hand, the significantly lower than expected dynamics of the development of renewable energy sources, and on the other hand, the growing role of Azerbaijani national companies in the market of liquid fuels and natural gas in Georgia, are visible consequences of the emergent status quo.
    Pozbawiona własnych złóż surowców węglowodorowych Gruzja zdana jest na import. Zaniechanie z przyczyn politycznych ich zakupów w Federacji Rosyjskiej oraz braki infrastrukturalne (w tym brak terminalu LNG) doprowadziły do faktycznej monopolizacji dostaw ropy naftowej i gazu ziemnego z Azerbejdżanu. Z powodów geopolitycznych Gruzja pozostaje dla Azerbejdżanu jedyną drogą eksportową tych surowców. Łatwy dostęp do nich – z racji zajmowania pozycji państwa tranzytowego – nie pozostaje bez wpływu na tempo transformacji energetycznej w Gruzji. Znacząco niższa niż należałoby się tego spodziewać dynamika rozwoju OZE z jednej strony, a z drugiej rosnąca na znaczeniu rola azerbejdżańskich spółek narodowych na rynku paliw ciekłych i gazu ziemnego w Gruzji są dostrzegalną konsekwencją powstałego status quo.

    Opis:
    The drilling of any oil and gas well is accompanied by the use of drilling fluids consisting of chemical reagents and materials of varying degrees of environmental hazard. The existing drilling waste disposal technologies are expensive, energyand labor-intensive, and do not always contribute to the formation of environmentally friendly compounds. In this regard, the possibility of using destructor microorganisms capable of growing and exhibiting biochemical activity under the conditions of complex pollution, in an environment with a high content of hydrocarbons, surfactants and polymer additives capable of biodegrading these substances, is relevant. In connection with the foregoing, the search for new strains of bacteria for the disposal of drilling waste, which are resistant to the conditions of complex toxic effects of drill cuttings components and, at the same time, capable of providing a significant degree of detoxification of the reagents that are part of hydrocarbon-based solutions, is relevant.

    Opis:
    Diesel fuels currently constitute around 60–70% of the turnover of fuel bases in Poland. Diesel fuels are stored in vertical steel tanks with fixed roofs, which, according to applicable legal acts, do not require airtight sealing. This results in the emission of gases containing hydrocarbons to the atmosphere, which at high turnover of fuel bases generates the need to determine the concentration of hydrocarbons emitted to the atmosphere and to perform calculations of concentrations occurring at the boundary of the fuel base site. The article collects available literature data and presents the results of research on the emissions of hydrocarbons to the atmosphere that occur during handling and storage of diesel fuel in storage tanks, including the determination of the saturated vapor pressure of the hydrocarbon components of the tested diesel fuel depending on the temperature. The emissions tests were carried out by taking gas samples emitted during operations on diesel storage tanks. Analyzes of the gas samples supplied in gas-tight syringes were performed with SRI 8610C gas chromatograph equipped with a flame ionization detector (FID) and an alumina packed column. Diesel oil sample analysis was performed by gas chromatography using Shimadzu GC-2010 Plus chromatograph equipped with flame ionization detector (FID). ZB-5HT column (30 m × 0.25 mm × 0.25 µm) was used for the separation of the substances. Research has shown the amount of hydrocarbon emissions to the atmosphere depending on the type of loading operations, the degree of storage tank filling and oil temperature. The dependence of the concentration of hydrocarbons emitted from the storage tank depending on the degree of filling of the tank has been determined in the research. Results of calculations of diesel vapor pressure show convergence with most available literature data and measurement results. General design guidelines have been defined to determine the data necessary to calculate the level of hydrocarbon concentrations in atmospheric air. The research was aimed at creating the basis for the required environmental calculations, relevant in the absence of relevant literature data, necessary for the reliable determination of the amount of hydrocarbon emissions.

    Opis:
    The aim of the study was to assess the impact of diesel oil on the activity of oxidoreductases in loamy sand, and to evaluate effect of selenium addition in the restoration of homeostasis of soil contaminated with diesel oil. The experiment was carried out under laboratory conditions with loamy sand. 0.05 mmol/kg of selenium (Se(IV) or Se(VI)), and diesel oil in the doses of 2, 10 and 50 g/kg were added to the soil samples. In soil treated with selenium and diesel oil activities of dehydrogenases, catalase, o-diphenol oxidase and nitrate reductase were measured on 1, 7, 14, 28, 56 and 112 day of the experiment. Contamination with diesel oil did not cause significant changes only in the activity of o-diphenol oxidase. The highest increase was observed in activity of dehydrogenases. Selenium limited hydrocarbons impact on activity of soil oxidoreductases, especially in loamy sand with diesel oil in the dose of 10 g/kg. Obtained results showed that this effect was reduced after treatment with selenium in both oxidation states but for nitrate reductase and catalase this reduction was reported after application of Se(VI) and Se(IV), respectively.

    Opis:
    The proposed article involves an investigation of the processes taking place during the preparation of mixed fuels that are combined directly before combustion. The fuel dose formed in this way must take into account the qualitative and quantitative composition of the fuels and the amount of air in the process. Given that liquid fuels similar to gasoline (e.g. methanol, ethanol, butanol) are characterized by different properties, their comparison would be useful in order to use their ratio to influence the combustion process. The process of fuel preparation plays a decisive role in this issue. The article describes abilities of modelling the injection of various fuels simultaneously to the combustion chamber for creating fuel mixture directly before ignition. First part of the article consists of analysis of light hydrocarbon fuels mixing abilities, supported with present research data. Next part describes the evaluation of execution of the assumed system – two fuel injectors with analysis of spray penetration. The modelling of the injection and spray was performed in the AVL FIRE 2014.2 environment and the results were presented. The injection possibility was proven by injecting the fuel to the combustion chamber model. Local values of air-fuel ratio, density and ambient pressure were presented to better understand the potential in mixing fuels directly before ignition. The conclusion includes description of fuel mixing abilities, influence of various fuels on creation of a stratified mixture and definition of controllability of charge ignition.

    Opis:
    Term “jet fuel” is well known and recognized worldwide - it applies to aviation product used to power all turbine engines in aircrafts and helicopters. Its’ properties are clearly and strictly defined in international specifications. However, in the discussion concerning jet fuels, and in most research material, many people seem to forget that this fuel is a mixture of different hydrocarbons, is produced from different feedstock (crude oil from different sources available worldwide) and as a final product is obtained with different production processes. Thus, however jet fuel must meet the requirements defined in international standards, these fuels differ each other and as a result, differences can be observed in logistic chain and in combustion process. This paper points out some differences between jet fuels and its aim is to convict users, researchers and all people in aviation industry dealing with jet engines operation, that - when talking about jet fuel - many factors and details about final product must be considered, and this type of product should not be seen as single-type fuel, as most people see it now. The article has been prepared within the research project funded by the National Science Centre in Poland and granted with decision no. DEC-2011/01/D/ST8/06567.
