Opis:: The problem of effective technology for heavy oil recovery nowadays has a great importance, because of worsening geological conditions of the developed deposits, decreasing recovery factor, increasing the part of heavy oil. For the future sustainable development of oil producing industry the involved technologies must require energy effectiveness and ecological safety. The paper proves the enhanced oil recovery methods necessity for heavy oil deposits, highlighted thermal technologies as the most effective. But traditional thermal treatment technologies is a source of air pollutant emission, such as CO, NO etc. The calculation of emissions for traditional steam generator is provided. Besides, the paper shows the effectiveness of electrical enhanced oil recovery methods. The advantages of associated gas as a fuel for cogeneration plants is shown. The main approaches to implementation of carbon dioxide sequestration technologies in the oil and gas industry of Russia are defined. Conceptual view of СО₂-EOR technologies potential within the context of sustainable development of oil and gas industry are presented. On the basis of the conducted research a number of scientific research and practical areas of the CCS technology development are revealed.

Opis:: The use of heavy metals in the manufacturing industry over the past few decades has eventually contributed to a rise in the flow of metallic compounds into wastewater and has raised significant ecological and health threats to living things. Adsorption is an excellent way to treat solid waste effluent, offering significant benefits such as affordability, profitability, ease of operation and efficiency. However, the price of commercial adsorbent namely activated carbon has soared due to its high demand. There is also a green improvement in this method by turning the commercial adsorbent into agricultural waste. In Malaysia, the oil palm waste is such suitable material that can be utilized for making activated carbon, since they are ample and easy to find. Additionally, part of them is agricultural waste that cannot be consumed (i.e. leaves and fronds). Hence, this study aimed to analyse the potential of activated carbon from agricultural waste, namely oil palm waste, in reducing the levels of heavy metals in industrial wastewater.

Tytuł:: Assessing the Environmental Condition of Minor Rivers in Urban Areas

Tematy:: sediment pollution

Opis:: This article is devoted to the study of water and sediment pollution in the channel of the Neva delta. Spectrophotometry was used to determine the concentration of pollutants in water. In the chemical analysis of the precipitate, atomic absorption spectroscopy and infrared spectroscopy were used. Analysis of the hydrochemical composition and sediment of the Smolenka River showed high concentrations of heavy metals and petroleum products. At the same time, the hydrochemical composition of the Smolenka River is highly unstable, but the concentration of oil products and lead in the sediments indicates the presence of local pollution sources. Based on our findings, we are guided by the restoration of the aquatic environment.

Opis:: The ecological risk and source apportionment of heavy metals and hydrocarbons in soil from the study site was carried out. Composite soil samples (n = 48) were collected from 3 sampling points (SP 1, SP 2, SP 3) within the site at 50, 200, and 500 meters, respectively, from the oil well and from a control site (Ibagwa, Abak) at 10,000 meters from the study site, using a hand-held auger. The samples were analyzed for heavy metals using inductively coupled plasma atomic emission spectrometry (ICP–AES, Yobin Yvon JY-24) and total petroleum hydrocarbon (TPH) using Agilent 6890N Gas Chromatography - Flame Ionization Detector (GC– FID model, Japan). Mean levels of heavy metals and TPH were higher in the study site compared to the control. The mean levels of heavy metals were 0.748 mg/kg (Pb), 0.754 mg/kg (Cd), 1.577 mg/kg (Ni), 0.274 mg/kg (Cr), 4.749 mg/kg (Fe), 0.020 mg/kg (V), 0.103 mg/kg (Co), 0.181 mg/kg (As), 5.544 mg/kg (Mn), and 5.187 mg/kg (TPH). The heavy metals in the soil had an increasing sequence of V

Opis:: The article provides the results of studying the effect of 0.1, 1.0, 2.5, 5.0, 7.5, and 10% aqueous suspensions of bottom ash and technical carbon on the germination vigor of the seeds of oil flax and the environmental safety of its use in terms of the content of heavy metals. Laboratory experiments were performed at the environment lab, field experiments – at the experimental field of the Kokshetau State University n.a. S. Ualikhanov. The laboratory germination vigor of the seeds, the length of seedlings, and the mesocotyl were determined according to the Interstate Standard Agricultural Seeds GOST 12038–844. In the field experiment on studying dosages of introducing the drug, the content of heavy metals was determined by the method of stripping voltammetry. The preparation is a mixture of bottom ash and technical carbon in the ratio of 2:1. It has been found that the use of a 5% aqueous suspension of the preparations contributes to increasing the laboratory germination to 97.0% (88% in the reference), the length of the mesocotyl to 80 mm (55 mm in the reference), the length of roots to 79 mm, and the weight of germinated seeds to 1.6 grams (in the reference, these values were 46 mm and 0.6 g, respectively). After the introduction of the preparation made of bottom ash and technical carbon at the dosages of 100, 200, 300, 400, and 500 kg/ha, the content of heavy metals insignificantly increases, compared to the reference, but does not exceed the permissible levels in the soil, in the stalks, and in the grains of oil flax; that is, the introduction of the preparation into the soil at the dosages of 100 – 500 kg/ha is ecologically safe. The experimental data have shown that the maximum effect is ensured by pre-sowing treatment of oil flax seeds with a 5% solution of aqueous suspension made of bottom ash and technical carbon, where the laboratory germination capacity of the seeds increased by 10.2%.

Opis:: Oil pollution is a hazard both in terms of scale and toxicity. Oil and oil products cause poisoning, death of organisms and soil degradation. The natural self-purification of natural objects from pollution depends on the natural conditions of the region, the presence of moisture, heat and the activity of the vital activity of the soil biocenosis. Under the conditions of Siberia, where a low temperature regime is maintained for a long time, self-purification is a long process. As a result of the long industrial use of the Medvezhye oil and gas condensate field, the soils of this area have accumulated pollutants. Thus, it is required to assess the toxicity of the soil, as well as to provide the ways and methods to prevent its environmental pollution. One of the ways to restore disturbed landscapes is technical and biological reclamation, the features and results of which are considered in this study using the Medvezhye deposit sand pit as an example.
