Opis:
From the beginning of the 20th century until the interwar period, Poland was at the forefront of crude oil producers in the world, and then in Europe. Poland, as a result of war damage, and first of all territorial changes that occurred after World War II, lost significant resources of this raw material. At the same time, the development of oil demand, related to the economic recovery of the country, contributed to the need to develop imports, which during 1990-2017 increased from 13.0 million tons to over 24.0 million tons of crude oil. Poland, due to the technical configuration of domestic refineries, as well as the availability of the "Przyjaźń” pipeline, imports crude oil mainly from Russia. However, Polish refineries have the opportunity to develop alternative sources of supply through the availability of Naftoport in Gdańsk. Thus, the progressive diversification of supplies, causes a decline in the share of Russian oil (from 95% during 2001-2005 to 74% in 2017), for the benefit of raw material from the Middle East, but also North America or other European countries. The extraction of crude oil from domestic deposits increased in the analyzed period from 0.15 million tons to 0.94 million tons in 2017, but in recent years it covers only 3-4% of domestic demand.

Opis:
The objectives of this work were concentrated to investigate the enhancement of petrol distillate production from crude oil after treating with two additives. Attempts were also made to find out the mechanisms, those are responsible for enhancing the quantity and quality of petrol from crude oil by straight run refining process. From this study, it has been illustrated that the yield of petrol was directly proportional to the lubricating oil and inversely proportional to the bitumen asphalt content in the hydrocarbon mixture influenced by both physical and chemical reasons. The yield of petrol was increased ca. 4% (w/w) when 0.25% (w/w) additive-1 was used for blending before distillation. The physical properties of distillate petrol product were studied as well as the chemical quality was determined by TGA, 1H- NMR and GC-MS photometer.

Opis:
The effects of crude oils entering marine environment have been investigated since early 1960s when oil pollution became a subject of global environmental concern. Extraction and transportation of crude oils have been contributing to water pollution especially in closed water basins, such as the Baltic Sea. It was estimated that yearly oil input to the Baltic Sea amounts to 21-70 thousands of tons, which is twice higher than in the North Sea and three times higher than in the North Atlantic. Growing pollution loads into the Baltic Sea created a demand for multifarious studies on the environmental effects of oil products. In this study, we focus on bio-optical and ecological aspects of the presence of crude oil in seawater. Dispersed oil droplets occur in seawater as the result of contaminated river inflows, bilge water discharges and as the consequence of mechanical and chemical dispersion of oil spills. Their optical properties depend on oil type, concentration and size distribution. We present further results obtained from the developed fluorescence-based method for determination of the crude oil concentration in natural Baltic seawater and for evaluation of the oil droplets size by applying vacuum filtering. The results have been measured for the samples collected in Southern Baltic Sea during several ship cruises in 2012. We discuss the application of vacuum filtering in the fluorescence analyses in the context of laboratory, in situ and remote detection of dispersed oil.

Opis:
Despite of numerous actions undertook by the global and local authorities towards protection of marine environment, oil pollution loads into the Baltic Sea still tend to increase and need to be continuously estimated in order to apply the legal regulations. There is a demand for multifarious studies on the environmental effects of oil products. Dispersed oil droplets occur in seawater as the result of contaminated river inflows, bilge water discharges and as the consequence of mechanical and chemical dispersion of oil spills. Their optical properties depend on oil type, concentration and size distribution. Oil content influences many environmental factors, like water quality and bio-optical parameters (e.g. water-leaving radiance, inherent optical properties, seawater fluorescence). We present a unique study of the collected database of crude oil fluorescence spectra for better understanding the correlations between oil optical properties and its concentration, as well as for evaluation of the oil droplets size by the application of vacuum filtering using three filters of different permeability. Fluorescence spectra have been registered for oil-in-water emulsion samples prepared in the laboratory by mechanical dispersion. We discuss the optical properties of crude oil and the relationships between them in the context of potential remote detection of dispersed oil in seawater.

In his article, the author presents problems related to the functioning of the oil production sector in the world and in Poland. He also discusses the prospects of national entities of the sector. The two companies – Orlen and Lotos – have modern processing plants at their disposal thanks to which they can have products which allow for obtaining an optimal model margin. The capacity of the refinery in Płock, which is owned by Orlen, stands at over 16 million tons of oil annually. In the case of Lotos, the refinery in Gdańsk can process about 10 million tons of oil a year. The two refineries are favourably located which allows for obtaining raw material through two independent channels – Russian oil through the “Przyjaźń” pipeline, and various types of oil transported by sea by Naftoport and the system of pipelines managed by the PERN company.

Opis:
Media pipeline transportation, in particular energy commodities has a very high share in the world economy. It has many advantages over other methods of transmission of the products on land but there are concerns about the safety of the pipeline system. When we are designing the pipeline, we take into consideration maximal discharge pressure of medium, but any change in pumping parameters results the appea rance of an unsteady (transient) process, which in some cases may lead to a rapid increase in pressure. The largest increase in pressure in the pipeline comes at a time of a complete stop fluid flow. There is formed a water hammer, which may cause a major accident up to pipeline leaks inclusive. Subject of considerations in the paper is the analysis of changes in pressure over time in the pipeline obtained in 12 experiments of stop oil pump unit in the trunk pipeline for different pumping parameters and properties of the medium. Based on the recorded changes of pressure in measurement points were fitted regression models allowing to forecast an increase in pressure along the pipeline route caused by water hammer.

Opis:
A device with a frequency-modulated output signal has been developed to increase the sensitivity and accuracy of measuring moisture content in crude oil and petroleum products in the range of 0~20%. The main element of the device is a self-oscillator transducer based on a transistor structure with negative differential resistance. A capacitive sensor in the form of a capacitive cylindrical structure with cylindrical electrodes was used to determine moisture content in crude oil and petroleum products. Electric permittivity of a two-component mixture of oil and water was estimated and the capacitance of the humidity-sensitive capacitive cylindrical structure with cylindrical electrodes was calculated. An electrical diagram of the device for measuring and controlling the humidity of crude oil and petroleum products has been developed. The relative error of converting the humidity of oil and petroleum products into capacitance which was caused by the change in oil temperature, was determined to be 0.225%. Values of relative errors of the device for measuring the humidity of oil and petroleum products are as follows: 1.355 · 10-5% is caused by instability of the oscillator frequency, 0.01% is caused by fluctuations in the supply voltage of the self-oscillator transducer, 0.05% is caused by a change in ambient temperature by 1°C. For the developed device, which used errors of the first and second type, the reliability of humidity control of oil and petroleum products has been determined to be 0.9591.

The article presents the results of theoretical and experimental studies on the mechanical activation of viscous oil, which confirmed the effectiveness of cavitation on their rheological properties. The major making source of raw materials of oil branch stocks heavy and bituminous crude oils are. Improvement of technologies transportations it is, caused by their high resource potential. Capacity and economic efficiency of the oil pipeline depends on properties of the pumped-over oil. The main obstacle for ensuring necessary speed is viscosity. Recently the steady tendency to magnification of bulks of haul, oil and oil products was out lined. Thus, for problem solution on magnification of bulk of an oil pumping and oil products, developments new or optimization of applied technologies of haul of crude oil and crude oil products taking into account their rheological behavior and operating characteristics of pipelines are indispensable. With that, end in view the big practical and theoretical interest is, represented by working out of new methods of struggle against formation of paraffin adjournment. Considering problem urgency, from our party experiences on influence studying cavitation on formation asphaltene - pitch - paraffin adjournment on an internal surface of the pipeline have, been spent. The possibility of an intensification of process of influence of chemical reagent by cavitation for decrease in viscosity of oil is established. Results of pilot studies on complex influence of chemical reagents and cavitation on viscosity crude oil with various structural and group structure are received. As have shown experiments, as a result cavitation in oil there are irreversible changes of viscosity, pressure of sated steams, shares: paraffin, asphaltene and pitch hydrocarbons.

Opis:
Gospodarka Polski w głównej mierze bazuje na paliwach kopalnych. Najważniejszym nośnikiem energii pierwotnej jest węgiel, chociaż jego udział w krajowym bilansie paliwowo-energetycznym rokrocznie maleje. Drugim, pod względem zużycia, surowcem energetycznym jest ropa naftowa. W 2015 roku przemysł rafineryjny odnotował rekordowy wynik przerobu w wysokości 25,9 mln Mg. Rosnąca konsumpcja produktów petrochemicznych oraz wzrost mocy przerobowych krajowych rafinerii pozwoliły osiągnąć tak wysoki wynik. Uniwersalność ropy naftowej pozwala na uzyskanie produktów o różnym zastosowaniu. Należą do nich między innymi: olej napędowy, LPG i etan, paliwo lotnicze, benzyna silnikowa, oleje bazowe do wytwarzania środków smarnych, asfalty, woski naftowe. W artykule przedstawione zostały zmiany, jakie zaszły w strukturze krajowego zużycia oleju napędowego, LPG i etanu, benzyn silnikowych oraz paliw lotniczych w latach 2004 − 2014. Analizie poddano produkcję krajową, import oraz eksport. Konsumpcja oleju napędowego, LPG i etanu oraz paliwa lotniczego wzrosła w rozważanym okresie. Zmalało natomiast zużycie całkowite benzyn silnikowych. Analogicznie nastąpiły zmiany w produkcji krajowej. Wolumen importu zmniejszył się, a eksportu wzrósł dla każdego z przedstawianych produktów rafinacji ropy naftowej.
The economy in Poland is based mainly on fossil fuels. The most important primary energy carrier is coal, although its share in the national fuel and energy balance is still decreasing. In terms of consumption, crude oil is in the second place of energy resources. The Polish refinery industry reached a record result, namely 25.9 million Mg in 2015. The growing consumption of petroleum products and an increase in the capacity of domestic refineries allowed such a high score to be achieved. The versatility of crude oil allows products for different purposes to be obtained. These include: diesel, LPG and ethane, aviation fuel, motor gasoline, base oils for lubricants preparation, asphalts, petroleum waxes. The article presents the changes which have taken place in the structure of domestic consumption of these products from 2004–2014. The author has analyzed domestic production, import and export. The consumption of diesel, LPG, ethane, and aviation fuel increased in that period. The consumption of motor gasoline decreased, as did domestic production. The volume of the import decreased, while the export increased for each of the presented refined petroleum products.

Opis:
Relative permeabilities relationships as a function of fluids saturation are one of the most important parameters for describing multiphase flow processes in reservoir rocks. When direct laboratory tests are not available for investigating oil-water multi-phase flow in rocks, then indirect prediction techniques using relative permeability functions are widely used, e.g. from capillary pressure test. In this study the measurement of capillary pressure was performed on rocks plugs with different characteristics at reservoir conditions using porous plate method. During measurement semi-permeable membrane was used with 15 bar threshold pressure, what allowed to register formation water saturation, at changing differential pressures steps. Desaturation at each pressure stage was continued until no more produced liquid was observed. Water saturation point at maximum capillary pressure applied is assumed to be final irreducible water saturation. Application of porous plate method provides sufficient stabilization time, allowing to achieve uniform saturation distribution. In this research, Brook-Corey model was used to predict relative permeability from experimental measured capillary pressure data for oil-water phase flow in porous media. As a result, it is possible to obtain more accurate capillary pressure outcomes, and relative permeability curves for the two-phase system, than other methods used in practice. Performing capillary pressure measurements at reservoir conditions, allows to restore the processes occurring in the reservoir.

Opis:
Analysis of factors shaping the market environment the oil sector in the European Union leads to the conclusion that the main elements having an impact on the profitability of refinery operations include their complexity index, access to a particular slate of crude oil, supply infrastructure (land premium, supply side, etc.) as well as laws and regulations regarding this very industry (both EU and national legislation). It should be emphasized that on the one hand European refiners compete against each other on national markets (including the EU market), on the other hand, however, they are vulnerable to competitive activity of refineries from outside of the European Union. Recent years clearly outline the downturn in the oil refining sector of the EU, that is manifested by idling the refineries, changes in their base model activity (conversion into the fuel and crude oil storage sites), or at best sector acquisitions by foreign companies (mainly from the Russian Federation). The progressive loss of capacity of oil refining on the Old Continent will cause significant changes in the energy security of fuel supplies, which simply, will have to be imported from abroad in the foreseeable future. In order to counteract the negative developments in the market, refineries affiliated with professional organizations (such as EUROPIA, Concawe) have taken an action in co-operation with the European Commission and the International Energy Agency aimed to develop the so-called pilot - horizontal control of refining sector efficiency (fitness check) involving the review of existing EU law. The purpose of this activity is to identify unnecessary burdens and unintended, negative impact of existing EU law on the sector. In line with the European Commission plans, the results of a fitness check are to be published in late 2014, yet the new non-legislative and legislative initiatives of the EU should take into account the context of the restoration of refinery competitiveness.

Opis:
W Polsce wzrasta znaczenie ropy naftowej w bilansie wykorzystania energii pierwotnej. Należy podkreślić, że obecnie potrzeby paliwowe w ograniczonym stopniu podlegaj ą regulacji, gdyż wynikają bezpośrednio z długookresowych zmian zachodzących w otoczeniu. Ponadto barierą dla prawidłowego funkcjonowania tego sektora są coraz częściej uwidaczniające się ograniczenia polityczno-gospodarcze zarówno w kraju jak i zagranicą. W związku z tym ukształtowany niekorzystnie dla odbiorców rynek, skłania do postawienia pytania o znaczenie poszczególnych czynników w procesie kształtowania aktualnych i przysz łych potrzeb paliwowych. Celem artykułu jest próba przeprowadzenia analizy zmian zachodz ących w krajowym otoczeniu i ocena ich wpływu na poziom zapotrzebowania na ropę naftową w Polsce w latach 1995-2006 oraz określenie ich znaczenia do roku 2015. Jego realizacja odbywa się poprzez metodę badawczą, która obejmuje następujące etapy: analizę otoczenia, ocenę otoczenia oraz ocenę szans i zagrożeń.
In Poland the importance of petroleum in the balance of the exploitation of primary energy has been considerably increasing. It needs to be emphasized that the present petroleum demand can only be regulated in a limited degree as it results from the long-term changes in the environment. Moreover, political and economic limitations which are more frequently apparent in and outside Poland are also a barrier to the proper functioning of the petroleum sector. As a consequence, the development of the market disadvantageous for the consumers triggers the questions concerning the significance of the particular factors in shaping the demand on petroleum at present and in the future. Therefore, the aim of this article is to analyze the changes in the domestic environment and to evaluate their influence upon the level of demand on petroleum in Poland in the years 1995-2006, as well as to determine their significance up to the year 2015. The stages of the research are: the analysis of the environment, the evaluation of the environment, the prognosis of the opportunities and threats.

The article discusses a very important problem of oil production. Oil, recognized as a major source of economic development, is the main energy source of the modern world. Unfortunately, Poland has limited oil reserves. However, the production, which meets only about 4% of the demand, is carried out. Oil deposits in Poland are found in the Carpathians, in the Carpathian Foredeep, in the Polish Lowlands, and in the Polish Exclusive Economic Zone of the Baltic Sea. Initially, deposits in the Carpathians were of the greatest economic importance, but these are already depleted to a great extent. Currently, oil deposits in the Polish Lowlands are of the greatest economic importance. The largest deposit is BMB (Barnówko-Mostno-Buszewo) near Gorzów Wielkopolski. In total, in Poland oil resources amount to 23 598.46 thousand tons, of which.37% accounts for industrial resources (14 482.15 thousand tons). The article presents crude oil resources in Poland by regions, i.e. Polish Lowlands, the Carpathians, the Carpathian Foredeep, and the Polish Exclusive Economic Zone The resources were divided into anticipated economic, industrial, undeveloped resources and abandoned deposits. In addition, the three Polish companies involved in the extraction of oil, namely PGNiG S.A., the LOTOS Group S.A. and ORLEN Upstream sp. z o.o., were presented. The locations where exploitation is carried out and the volume of oil production in the last few years were discussed.

Ropa jest podstawowym surowcem energetycznym w świecie i źródłem tak spektakularnego rozwoju gospodarczego jaki obserwujemy od czasu jest odkrycia. Polska jest niestety krajem ubogim w zasoby tego surowca, niemniej jednak prowadzone jest wydobycie, które zaspokaja zaledwie około 4% potrzeb. Zasoby ropy naftowej w Polsce znajdują się w Karpatach, w zapadlisku przedkarpackim, na Niżu Polskim oraz w polskiej strefie ekonomicznej Bałtyku. Początkowo największe znaczenie gospodarcze miały złoża w Karpatach, ale uległy one już w znacznym stopniu wyczerpaniu. Obecnie największe znaczenie mają złoża ropy występujące na Niżu Polskim. Największym złożem jest BMB (skrót od nazw miejscowości Barnówko-Mostno-Buszewo) koło Gorzowa Wielkopolskiego. Ogółem w Polsce zasoby ropy naftowej wynoszą 23 598,46 tys. ton, w tym zasoby przemysłowe 14 482,15 tys. ton, co stanowi,37% zasobów ogółem. W artykule przedstawiono zasoby ropy naftowej w Polsce z podziałem na regiony, tzn. Niż Polski, Karpaty, Zapadlisko przedkarpackie, oraz polską strefę ekonomiczną Bałtyku. Zasoby podzielono na zasoby bilansowe, przemysłowe, niezagospodarowane oraz złoża, w których zaniechano eksploatacji. Przedstawiono również trzy polskie firmy, które zajmują się wydobyciem tego surowca, czyli PGNiG S.A., Grupę LOTOS S.A. oraz ORLEN Upstream sp. z o.o. Pokazano miejsca, w których prowadzona jest eksploatacja oraz jej wielkość w kilku ostatnich latach.

Opis:
W artykule przedstawiono mechanizmy wydzielania się soli w wielofazowych układach charakterystycznych dla płynów złożowych. Następnie opisano zasady separacji płynów złożowych podczas wydobycia ropy naftowej. Szczególną uwagę zwrócono na rozdzielanie wysokozmineralizowanych solanek od ropy naftowej. Przeanalizowano składy wód złożowych na wybranych krajowych kopalniach ze względu na zawartości soli. Określono zawartości chlorków w ropach surowych po pierwszym stopniu separacji oraz możliwości wydzielania się soli w urządzeniach wydobywczych. Wskazano na sposoby likwidacji emulsji i odsalania ropy naftowej oraz przeciwdziałania wydzielania się dużych aglomeracji solnych.
The mechanisms of precipitation in polyphase characteristic arrangements the salt for were introduced brine in article. The principle of separation of brine was described during exploitation of crude oil. Special attention was paid to distributing highly mineralized brines from oil. The compositions of brines were analyzed on the example of selected Polish mines with regard to salt content. The chlorides content was qualified for crude oils after the first degree of separation, and the possibility of precipitation in mining devices the salt was verified. The ways of liquidation of emulsion and salt removal from the crude oil were indicated and the measures against precipitation of large saline agglomerations.

Opis:
The article summarizes recent events related to the crude oil market, regarding particularly the policy of reduction in the commodity supply introduced by the countries of the OPEC cartel and Russia. The author examined the next steps undertaken by member nations of the oil association, which were targeted at an increase in the price of oil and at lowering the level of crude oil reserves in the OECD countries. In addition, the process of creating a shale revolution in the United States was outlined, which led to a great level of independence of this country from the supply of energy resources from other parts of the world. The article is an attempt to introduce a wider topic which is the shale revolution in the USA, and its and impact on the global oil market. It is also a starting point for further considerations regarding possible steps of the OPEC cartel arising after expiration of the current agreement.

Opis:
This paper examines the development of oil prices in the last years and its impact on energy security of the southern Europe countries. The development of oil prices in the last years has a potential impact on all economies. Indeed the impact was positive for crude oil importing economies but in the other hand, negative impact on crude oil exporting economies. According to our analysis, the impact was positive on all southern Europe economies, regardless the scale of the impact. Off course the low crude oil prices improves the affordablity of energy supply, but for the energy security of southern Europe countries should be insured by other alternative energy resources, among them natural gas and renewable energy resources.

Opis:
In this study, comparative potential effects of commercial activated carbon (CAC) and plantain peel-derived biochar (PPBC) of different particle sizes and dosage to stimulate petroleum hydrocarbon biodegradation in soil were investigated. Microcosms containing soil were spiked with weathered Bonny light crude oil (WBLCO) (10% w/w) and amended with different particle sizes (0.02, 0.07 and 0.48 mm) and dosage (20, 30 and 40 g) of CAC and PPBC, respectively. The bioremediation experiments were carried out for a period of 28 days under laboratory conditions. The results showed that there was a positive relationship between the rate of petroleum hydrocarbons reduction and presence of the CAC and PPBC in crude oil contaminated soil microcosms. The WBLCO biodegradation data fitted well to the first-order kinetic model. The model revealed that WBLCO contaminated-soil microcosms amended with CAC and PPBC had higher biodegradation rate constants (k) as well as lower half-life times (t1/2) than unamended soil (natural attenuation) remediation system. The rate constants increased while half-life times decreased with decreased particle size and increased dosage of amendment agents. ANOVA statistical analysis revealed that WBLCO biodegradation in soil was significantly (p = 0.05) influenced by the addition of CAC and biochar amendment agents, respectively. However, Tukey’s post hoc test (at p = 0.05) showed that there was no significant difference in the bioremediation efficiency of CAC and PPBC. Thus, amendment of soils with biochar has the potential to be an inexpensive, efficient, environmentally friendly and relatively novel strategy to mitigate organic compound-contaminated soil.

Opis:
Fossil fuel is the main source for CO2 emissions that causes global warming. This fact is the starting point for this paper, that consider on three different sources of data: crude oil used to calculate CO2 emissions for Iraq for the period from 1980 to 2018; annual data of total CO2 emissions available from the Carbon Dioxide Information Analysis Center (CDIAC) for Iraq and the world for the period from 1980 to 2014; and CO2 concentrations for Iraq for the period from 2002 to 2006 and for the world for the period from 1980 to 2018. The result is a multifaceted according to the dataset sources. Carbon dioxide emissions calculated from Iraqi crude oil was increased from 1.29 Mt in 2012 to 1.97 Mt in 2018. The world and Iraq CO2 emissions with different slop of average line that was 0.5 for world, 0.003 for Iraq, while increased exponential function from 2008 to 2014 to reach 36 and 0.17 Mt, respectively. The highest value of Iraqi CO2 concentration was 403 ppm in 2016, while the global CO2 concentrations slowly increased with slop line equal to 1.75 ppm per year, from minimum value of 338.6 ppm was in 1980, while maximum value of 407.05 ppm was in 2018, that’s mean no decreased in CO2 concentration unless emissions addressed.

Opis:
This present research work was conducted to determine the phytotoxic effects on tropical native plants, Ludwigia octovalvis, in order to assess its application for phytoremediation of crude oil sludge in contaminated sand. For this purpose of study, L. octavalvis plants were planted in containers containing different proportion of spiked real crude oil sludge in sand (10%, 50%, and 100% (v/v)). Degradation of crude oil sludge by L. octovalvis was measured in terms of total petroleum hydrocarbons (TPH) and was compared with TPH degradation inside control crates without plants. The findings indicated that the average TPH removal after a prolonged 42-day exposure period was high. The degrees of TPH degradation were 67.0, 42.4 and 46.2% in sand spiked with real crude oil sludge at 10, 50 and 100% respectively, whereas the degradation was only 34.7, 29.1 and 20.5% for the unplanted containers at the same respective proportions of crude oil sludge in sand. These findings give evidence that L. octovalvis has the capability to degrade hydrocarbons in crude oil sludge.

Opis:
In recent years, the world natural gas market is changing mainly due to the wid-er access to LNG (Liquefied Natural Gas). This technology allows to trade between the market participants all over the world. The natural gas prices on the American and European market are benchmarked to Henry Hub and National Balancing Point (NBP) natural gas. The goal of this paper is to investigate whether the listings of natural gas in the derivatives markets are linked and to analyse the relationship between natural gas and crude oil prices. We show that the probability distribution of returns is not normal and that there is a strong ARCH effect. We use multivariate GARCH model to describe the linkages between several series. We take into account two return series of natural gas futures contracts (Henry Hub and National Balancing Point) and two returns series of crude oil futures contracts (West Texas Intermediate and Brent) to measure the strength of linkages across two commodity markets of the most important fossil fuels.

W artykule przedstawiono ropę naftową jako główny surowiec energetyczno-przemysłowy oraz warunki wzrostu i rozwoju bakterii i grzybów w produktach ropopochodnych, które w następstwie powodują rozkład węglowodorów i dodatków uszlachetniających. Następnie opisano problem i występujące rodzaje zanieczyszczenia paliwa i oleju silnikowego ze szczególnym uwzględnieniem zanieczyszczenia mikrobiologicznego, którego konsekwencją jest powstawanie osadów, widocznych jako cząstki stałe, stanowiące mieszaninę żywych i martwych komórek oraz nieorganicznych produktów ubocznych. Scharakteryzowano również obecnie stosowane metody zwalczania mikroorganizmów w produktach ropopochodnych, do których należą między innymi zastosowanie biocydów mające znaczne skutki uboczne dla środowiska naturalnego, w wyniku czego istnieje potrzeba prac nad środkami przyjaznymi środowisku naturalnemu. W kolejnej części artykułu omówiono środek biobójczy nowej generacji - nanosrebro, czyli mikroskopijne cząsteczki srebra, jego właściwości i mechanizm działania. W ostatniej części artykułu pokazano obecne zastosowania nanosrebra w różnych dziedzinach życia i możliwości jego użycia do zwalczania mikroorganizmów w produktach ropopochodnych.
