Opis:: The paper presents studies on oil removal from soil by means of water elution with a help of shaking out the contaminants from the soil. The tests were performed on simulated soil samples contaminated with a mixture of petroleum hydrocarbons. The study consisted in recording the time influence and the number of elution cycles to remove contaminants from the soil. The samples were then subject to the determination of petroleum hydrocarbons, aliphatic hydrocarbons, and BTEX compounds (benzene, toluene, ethylbenzene, xylene). Due to adding various concentrations of petroleum into particular soil samples and applying different shaking times, it was possible to find out the impact of petroleum content and sample shaking duration on the course and possibility of petroleum substances removal by means of elution process.

Opis:: Contamination of soil and water with petroleum during its extraction, collection, transportation, storage and preparation occurs frequently, and purification of oil spills is one of the pressing environmental problems of oil producing organizations. There are a large number of methods for utilization oil spills. The sorption method in combination with bioremediation is capable of effectively purification of petroleum contaminated soils. The paper shows the possibility of using a carbonized mixture of shungite from the Koksu deposit (Kazakhstan) with rice husk as a sorbent and carrier of microorganism strains. The physicochemical properties and elemental composition, as well as the microstructure of carbonized samples were established. The maximum sorption capacity of carbonized sorbents when purifying the soil samples from oil from the Karazhanbas field was 1.86 g/g after 60 days. The carbonized samples with microorganism strains immobilized on them showed a degree of oil destruction reaching 90%.

Opis:: The paper deals with one of important ecological problems – utilization of associated petroleum gas (APG) at oil fields. An example of APG usage as a fuel for gas turbine power plants is examined. Among possible topologies of power plants the focus is put on the structure based on turbines with combined diesel-gas supplying for increasing reliability of power generation in case of failures in the system of preparation of APG. In order to ensure correct transition of turbines from gas to diesel supplying it is important to know responds of the system to the interruption of gas supplying. Based on the fundamental principles of thermodynamics and fluid dynamics gas-turbine power plant simulation model has been developed utilizing MATLAB/Simulink environment. Using the model allowed revealing the influence of load-sharing among the turbines of different types on the transition to an additional source of turbine fuel. Based on simulation results, recommendations have been worked out for the improvement of the reliability of gas turbine power plant.

Opis:: Ropa naftowa i jej pochodne stanowią jedno z głównych zanieczyszczeń środowiska gruntowo-wodnego w Polsce. Przykładem tego jest wylewisko odpadów z odwiertów wydobywczych ropy naftowej w Lipinkach koło Gorlic, gdzie prowadzi się rekultywację. W pobliżu zbudowano instalację do oczyszczania zawartości wylewiska, z zastosowaniem mikroorganizmów. Ziemia jest oczyszczana z węglowodorów, a następnie zawrócona do wyrobiska. Powierzchnia oczyszczonej ziemi zostanie zrekultywowana biologicznie stosownie do roślinności na terenie przyległym. W artykule przedstawiono fizyczne, chemiczne i mikrobiologiczne właściwości zawartości wylewiska oraz redukcję zawartości poszczególnych trakcji węglowodorów (C7-C36) w kolejnych etapach oczyszczania. Badania potwierdzają skuteczność zaproponowanej metody rekultywacji środowiska, która może być zakończona w okresie 5 lat.
Petroleum and its derivatives constitute one of the main sources of pollution of the groundwater enviroument in Poland. Au example of such pollution is the spillage site of waste from the petroleum extraction boreholes at Lipinki near Gorlice where the reclamation has been conducted. Au installation was built near the site to clean up the content of the spillage site using microorganisms. The earth is being purified by removing hydrocarbons and then retuned to the site. The cleaned surface will be subject to biological reclamation taking account of the vegetation growing in the surrounding area. In the paper the physical, chemical and microbiological properties of the spillage site content were presented as well as the reduction of contents of respective carbohydrate fractions (C7 - C36) during the successive stages of purification. The effectiveness of the proposed method of environmental reclamation was corroborated by the study results. The reclamation may be due to be terminated over a five year period.

Opis:: Public crude oil fields in Wonocolo sub-district were active from 1942 until now and have inadequately operated. The aims of this research were to measure the level of total petroleum hydrocarbon (TPH) pollution and their distribution in soil and surface water at the Wonocolo public crude oil fields. Twelve composite soil samples were collected from uncontaminated and contaminated sites of old well (OW), transportation line (T), and refinery area (R) at the depths of 0–30 cm, 30–60 cm, and 60–90 cm. The composite surface water sample was obtained from two points with different distances from the river side. TPH from soil and surface water samples were extracted using soxhlet and gravimetric method. Quantification of TPH was performed using Fourier Transform Infrared (FT-IR) Spectrometer. From the results of this study, it was concluded that soils and surface water are contaminated by TPH of 119.80–107,190 µg/g and 211,025.73 µg/L, respectively. TPH is clearly located in the upper of 0–30 cm depth at OW, T, and R sites (52,328.14–107,189.63 µg/g). These concentrations exceeded the soil quality standard of TPH and classified as category A for human hazard risk. The findings from this study show that there are considerable health risks which are potentially poisonous to humans in the local area. We recommend that remediation could be conducted using biological methods to reduce TPH pollution level.

Opis:: Creation of rain sewer is connected with dehydration of roads and coexisting objects. The paper presents a discussion upon the issue of groundwater contamination by petroleum compounds and other pollutants from transport based on studies of groundwater within the parking lots. The study included 9 parking areas, including 7 in Bialystok, 1 in a residential area outside of Bialystok in Ignatki, and one in Kleosin. The tested waters were subject to determination of COD, total suspension, and petroleum substances expressed as a mineral oil index. The studies have shown that the concentrations of determined parameters were in most cases proportional to the larger runoffs and concentration of petroleum compounds increased with the increase of suspension. It has been shown that from part of the parking lots, the meteoric water was discharged directly into watercourses and exceeds the permissible limits regulated by the Decree.

Opis:: Experimental studies on the dynamic sorption of model mixtures containing petroleum products were performed. The subject of the study was the modified sorbent from the ash-and-slag wastes accumulated in the ash dump of the Novocherkassk State District Power Plant (SDPP) (Russia, Novocherkassk, Rostov Region), obtained using the method of ash removal. The quantity of the sorbent for each model solution was fixed at 5.0 g. The model solutions in the amount of 1 dm³ were passed through a column filled with the modified sorbent at constant filtration rate w = const with filtrate takeout of 0.1 dm³/min. The pH value of the solution, which is advisable for extracting petroleum products, was determined experimentally. For this purpose, the model solutions, containing 100 mg/dm³ of petroleum products with pH = 1.65, 4.01, 6.86, 8.12, 9.18, and 11.34, were prepared. The optimum pH value of the solution was considered pH = 7.5. The content of petroleum products in the filtrate in all experiments was determined using IR spectrometry. The working range of water pollution with petroleum products was determined on a series of model solutions containing petroleum products in the range between 0.5 and 10 mg/dm³ with the increment of 0.5, between 10 and 100 mg/dm³ with the increment of 10, and between 100 and 1,000 mg/dm³ with the increment of 100. The maximum extraction of petroleum products from the solution was 88.23%. The applicability of the Henry’s law to the range of petroleum products concentrations in the filtrate of 50 mg/dm³ was confirmed. The adsorption equilibrium constant (Henry’s law constant) was determined experimentally. The effect of the natural freshwater matrix on the degree of petroleum products extraction was studied; no significant effect on petroleum products sorption was found. A conclusion was made that the sorbent can ensure the efficiency of water purifying from petroleum products of no less than 85% in the range of pollution between 5 and 300 mg/dm³.

Opis:: This present study to determine the potential of Neptunia oleracea as a phytoremediation agent for petroleum liquid waste in terms of various parameters such as physical temperature, and chemical parameters, namely pH, sulfide, and ammonia. Crude oil liquid waste is a hazardous waste if discharged directly into the environment, especially water. In this research, a method of biological treatment of petroleum liquid waste was used by utilizing aquatic plants, namely Neptunia oleracea. Phytoremediation is a way to treat waste that still contains contaminants thus levels can be minimized and even accumulated by various types of plants. This phytoremediation technique uses a simple bioreactor with various concentrations of petroleum liquid waste, namely control (0% waste), 10% waste, 20% waste, and 30% waste. The results of this study can be seen that the Neptunia oleracea plant is able to survive in petroleum liquid waste with a treatment time of approximately 3 weeks. In testing the levels of ammonia and sulfide after treatment showed fluctuating results from week to week. This is a response from Neptunia oleracea which uses these compounds in its metabolic processes. The ability of Neptunia oleracea to reduce sulfide and ammonia levels indicates that this plant can be used as a phytoremediation agent for petroleum liquid waste.

Opis:: The paper presents the results of field and laboratory studies aimed at studying the processes of oil transformation in the soil under the influence of natural biological processes during a two-year period on artificially created old spills. The soil of the study area was characterized as meadow. The high toxic effect of oil was confirmed, which was expressed in the complete extinction of soil flora and fauna. Despite the low oil content in the soil (less than 5%), soil self-purification processes were not observed. Moreover, the high sorption properties of the soil, the violation of the water regime and the lack of aeration led to the “conservation” of oil and significantly slowed down the natural processes of its biodegradation. This was confirmed by a slight change in the content of oil products a year after the start of the experiment, as well as the presence of free oil in the pore space of the studied soil.

Opis:: The following article is an analysis of designed processes of the life cycle of the most popular fuel for Diesel engines: diesel oil. This fuel is produced from petroleum, which is a non-renewable source of energy. Analysis was carried out with the assumptions of Life Cycle Assessment, which is a tool to test the environmental impact of the product. The life cycle of diesel was divided into five unit processes: petroleum extraction, transport of petroleum to the refinery, refining petroleum to diesel, transport of diesel to the recipient and utilization of delivered fuel by transport company. For every process the energy consumption and emission of carbon monoxide, nitrogen oxides and sulphursulphur oxides was calculated, with assumption of probable data, that could occur in real processes. The analysis has shown, that the process of refining petroleum is highly pollution-intensive. Also the combustion of diesel generates a significant amount of pollutants’ emission, which is why it is necessary to develop technologies that could contribute to the reduction of emission.

Opis:: Drilling sludge formed in the process of drilling wells using a drilling agent on a hydrocarbon basis looks like soft pasty mass of black color, with a distinct smell of petroleum products. Oil-based drill sludge has a high oil and chloride ions content, identified excessive concentrations of chromium 2.67 times. According to the degree of accumulation of heavy metals, that were distributed in the following order: manganese (Mn) > zinc (Zn) > copper (Cu) > chromium (Cr) > lead (Pb) > cobalt (Co) > arsenic (As) > mercury (Hg) > cadmium (Cd). The results of the particle size distribution indicate a significant proportion of physical clay, which peaks for the silt fraction – 63.60 %. During the study of the waste drilling agent was found that it includes oil products which reached level of 9000 mg/kg, while the hydrogen index refers to a neutral medium – 6.5 pH. The evaluation of the toxic effect of drilling waste according to the test-results has an acute toxic effect on the environment (hazard class IV). The significance of the research indicates the relevance of environmental assessment of drilling waste for the optimal choice of their subsequent disposal.

Opis:: Oil-containing wastewaters are regarded as main industrial pollutants of soil and water environments. They can occur as free-floating oil, unstable or stable oil-in-water (O/W) emulsions, and in the case of extreme organic load, as water-in-oil (W/O) emulsions. In this study two types of oily effluents, a typical O/W emulsion marked as E1 and a W/O emulsion E2, both discharged by local metal processing plants were examined to test their toxicity to microbial communities and the ability to serve as nutrient sources for bacterial growth. The organic contaminant load of the samples was evaluated on the basis of chemical oxygen demand (COD) parameter values and was equal to 48 200 mg O₂dm^-3 and >300 000 mg O₂dm^-3 for E1 and E2, respectively. Both emulsions proved to be non toxic to bacterial communities and were shown to contain biodiverse autochthonous microflora consisting of several bacterial strains adapted to the presence of xenobiotics (the total of 1.36 106 CFU cm^-3 and 1.72 10⁵ CFU cm^-3 was determined for E1 and E2, respectively). These indigenous bacteria as well as exogenously inoculated specialized allochthonous microorganisms were biostimulated so as to proliferate within the wastewater environment whose organic content served as the only source of carbon. The most favorable cultivation conditions were determined as fully aerobic growth at the temperature of 25 ºC. In 9 to 18 day-tests, autochthonous as well as bioaugmented allochthonous bacterial population dynamics were monitored. For both emulsions tested there was a dramatic increase (up to three orders of magnitude) in bacterial frequency, as compared to the respective initial values. The resultant high biomass densities suggest that the effluents are susceptible to bioremediation. A preliminary xenobiotic biodegradation test confirmed that mixed auto- and allochthonous bacterial consortia obtained upon inoculation of the samples with microbiocenoses preselected for efficient hydrocarbon biodegradation led to a decrease in the organic pollution level.
