Opis:
The scheme in which the Carpathians, Carpathian Foredeep and Polish Lowland are distinguished as the hydrocarbon prospective zones was used hitherto in Poland. Good geological diagnosis of Poland area enables to distinguish the petroleum provinces in terms of basin analysis (methodology). This procedure are based on an integration of multidisciplinary geological and geophysical data with into a petroleum play concept. Results of drillings and petroleum play procedures allow to predict boundaries of petroleum provinces. Effects of basin analysis with regards to the stratigraphy of hydrocarbon-bearing areas are presented in Figure 1. All these prospective areas (Fig. 1) have been matched into five independent units (Fig. 2) which could be defined as following petroleum provinces: Pomerania, Wielkopolska, Ma3opolska, Lublin and Gdansk. These petroleum provinces are only the parts of sedimentary basins the individual development of which enabled generation, migration and preservation of hydrocarbons. Location of the above mentioned petroleum provinces is also brightly reflected on the map of crustal consolidation (Fig. 3): every province in Poland has its own individual geologic history.

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:
Ultrasonic irradiation is one of the advanced oxidation methods used in wastewater treatment. In this study, ultrasonic treatment of petroleum refinery effluent was examined. An ultrasonic homogenizator with a 20 kHz frequency and an ultrasonic bath with a 42 kHz frequency were used as a source for ultrasound. The effects of parameters such as ZnO amount, ozone saturation time, and type of ultrasound source on the degradation of petroleum refinery effluent were investigated. The degradation of petroleum refinery effluent was measured as a change in initial chemical oxygen demand (COD) and with time. According to the results, degradation increased with the addition of ZnO in an ultrasonic probe. There was also a positive effect of ozone saturation before sonication then applying ultrasound on the degradation for an ultrasonic probe. It was observed that there was no positive effect of ZnO addition and ozone saturation on degradation for an ultrasonic bath.

Opis:
According to many intenstigations, oil pollution cause difficult changes of structure and function of natural ecosystems, as well as violation of metabolic processes, production and destruction of organic matter, and consequently leads to a decrease in species diversity. Studies show that planktonic animals are quite sensitive to oil pollution of sea water, which accelerates their death in the concentration of 0.01 mg·dm-3.

Opis:
Subject of this work was carrying out researches on removal of petroleum derivates in laboratory stripping tower. In researches model water was used, which was mixture of distilled water and petrol and diesel fuel mix in ratio of 1 to 3, next it was submitted to aeration. Repelling of petroleum derivatives was med in 4 series, starting researches from minimal concentration 0,132 µg/dm3 to 3,992 µg/dm3. Level of each concentration resulted from concentrations found in underground and superficial water based on researches made by authoress. As a result of stripping process outcomes were between 53,9 and 82,7%, lowest effects were achieved in III series – 44,8%. Observation was made, that during the process petroleum derivatives was removed gradually in III series, meanwhile in other series from the beginning high level of reduction was reached. Carried out stripping of petroleum hydrocarbons from water to air confirms relatively efficient method enabling lowering of their content to safe level. This process can be used to treatment of underground and superficial water with wide range of concentrations.

Opis:
Research background: The analysts of the petroleum product markets of industrial countries believe that the elasticity of demand varies at different periods, which gave rise to the hypothesis that behavioral and structural factors have changed the consumers? reaction during the last few decades, with a change in prices of petroleum products. Purpose of the article: The purpose of this article is to study the elasticity of demand and prices in order to identify changes in consumer behavior in the oil market after significant socio-economic shocks and to establish a correlation between changes in elasticity and price volatility, with the Ukrainian petroleum products market as an illustrative example. Methods: Based on the time series of the petroleum product market of Ukraine, static and dynamic models for assessing the demand elasticity were constructed. It was found that the time series of demand for petroleum products is non-stationary but then the time series of the first differences is stationary according to the extended Dickey-Fuller test; further, the fact of co-integration between time series of consumption, income, and prices was established by the Johansson test. This made it possible to construct co-integration dependence, allowing, in turn, the development of models for assessing the elasticity of demand for petroleum products, on the basis of which objective assessments of changes in consumer behavior were established. Analysis of the monthly calculation of petroleum products? price volatility during the period 2008 to 2018 has showed that the values of volatility increased abnormally in the period between the beginning of 2014 and the middle of 2015. The estimates of price and demand elasticities obtained for the two periods up to the beginning of 2014 and the second half of 2015 differ significantly from the values of the corresponding elasticities between the beginning of 2014 and the middle of 2015. Findings & Value added: Assessments of income elasticities and price elasticities for petroleum products in the Ukrainian market were obtained by three co-integration models, both short and long term, for each of the three previously defined time intervals. In one of them, characterized by a high level of price volatility conditionally referred to as a crisis, the value of elasticities differed markedly from the corresponding values in the other two periods, in particular, -0.383 for price elasticity and 1.068 for a long-term bond. In the other two periods, these were, respectively, 0.543 for price elasticity and 0.274 for long-term pre-crisis elasticity, and -0.470 for price elasticity and 0.235 for long-term post-crisis elasticity. Appropriate elasticity estimates were obtained for both the short-run and the dynamic model, for the same defined intervals. A comparison of these estimates showed the closeness of the values of elasticities for the pre-crisis and post-crisis intervals and a marked difference from the estimates of the elasticities in the crisis interval. Thus, it was found that a significant change in elasticities is accompanied by an increase in price volatility.

Genesis of rain sewage is connected with drainage of roads and objects linked with them. Its quality changes with flow intensity modification and rain duration. Devices used to rainwater treatment have great impact on environment. The aim of made research was evaluation of rainwater treatment effectiveness of selected separators located in Białystok. Storm water drainage is in 47,35% city area. City area is divided in 905 drainage basins (depends on area, rain intensity, flow rate, canal capacity) with differential areas (from 1,2 ha to 196,0 ha). To research there selected 4 separators and there were 6 sample taken in each point. In samples ChZT, BZT5, suspension, petroleum-benzine extractive substances and petroleum hydrocarbons were marked. Research results show us, that extraction of suspension and petroleum substances during heavy rain is ineffective.
