IMPACT OF OIL AND OIL PRODUCTS ON THE ENVIRONMENT

abstract 1251701022 issue 125 pp. 309 – 318 31.01.2017 ru 1783
This article is devoted to the influence of petroleum and petroleum products on the natural environment. There are the chemical composition of petroleum and the reasons for its detrimental impact on natural components. The pathways of petroleum and petroleum products in the natural environment were listed. There is a characteristic of the impact of these substances on all components of the natural environment, including soil, hydrosphere, living organisms. Consequences of such impact on each of the elements were listed. There are methods of fighting oil pollution and the need to make their application more expressed, as well as developing new, more effective ways

PAST AND PRESENT OF NANOTECHNOLOGY: NANO-POWDER TECHNOLOGY AS HYDROFOBISATION MEAN OF SURFACES OF DIFFERENT PHYSICAL NATURE

abstract 1121508094 issue 112 pp. 1291 – 1302 30.10.2015 ru 1582
In the context of nano-technological history, some possibilities of nano-powders possibilities are discovered. Through a very high dispersal property they remain on different surfaces, chemical neutral, withheld high temperature, not very expensive to treat surfaces in the process of hydrofobisation, non toxic. Some perspectives to use nano-powders in many fields of industry are discussed

PERFECTION OF CLEARING OF WATERS FROM PETROLEUM TECHNOLOGY

abstract 1271703025 issue 127 pp. 380 – 389 31.03.2017 ru 263
Nowadays there are sorbents, both natural, and modified, which allow to clear waters from variety of pollutants simultaneously, for example from ions of heavy metals and petroleum. We have received a new modified sorbent with use of a sol-method. The given sorbent represents beads in common besieged magnesium hydroxide and aluminum having layered structure. For the characteristic of the structure of the researched systems we have carried out an X-ray analysis. Studying the mechanism of interaction of the sorbent with ions of heavy metals was carried out with the use of the research of chemical structure of the sorbent and the condition of adsorbed ions by methods of IR spectroscopy and X-ray analysis. The conclusion was made, that modified inorganic sorbent on a basis of magnesium hydroxide and aluminum has a number of distinctive features and advantages comparing to other filtering materials

PURIFICATION OF OILY WASTEWATER BY USING NATURAL AND SYNTHETIC SORBENTS

abstract 1131509024 issue 113 pp. 297 – 306 30.11.2015 ru 1559
This article reviews the existing natural and artificial sorbents used for water purification from petroleum and petroleum products. A popular, widely used sorbents and new technologies, such as Versoil sorbent, sorbent based on the waste of olive oil production, sorbent-based waste felting production are considered. There are advantages of the use of a sorbent depends on its cost and the requirements to the quality of purification. There are advantages of the use of a sorbent depends on its cost and the requirements to the quality of purification. Main sorption properties of the most popular at the moment organic and inorganic sorbents are presented in tabular form, which allows them to conduct a comparative analysis. It was concluded, that the most promising sorbents were produced from plant waste

RESEARCH AND MODERNIZATION OF CRUSHING AND SORTING EQUIPMENT OF SAND AND SAND-GRAVEL MIXTURE

abstract 1001406093 issue 100 pp. 1435 – 1445 30.06.2014 ru 1350
The object of studying was CMD-108 crusher. The aim of this scientific article is studying kinetic and dynamic parameters of crusher operating devices. As a tool of studying there were used methods of mathematic analysis, theoretic mechanics and physics. As a result of theoretic studies there were defined speeds of various points of the crusher operating devices as well as there were obtained the values of dynamic loads on them and given recommendations on optimization of the crusher operating conditions and its designs. There was also determined an optimum zone of the material crushing from the viewpoint of operating life of the hinged joints of movable jaw enabling to reduce to minimum dynamic impact components of the reactions of the supporting joints of the movable jaw which increases their operating life

RESEARCH METHODS OF WATER PURIFICATION FROM POLLUTION WITH PETROLEUM AND PETROLEUM PRODUCTS

abstract 1131509025 issue 113 pp. 307 – 316 30.11.2015 ru 944
This article provides an overview of the currently existing methods of purification of waters from pollution with petroleum and petroleum products. The most popular cleaning ways and new emerging technologies are considered. For each method of combating with petroleum pollution the circumstances and the factors are given, under which the application of this method is the most efficient and cost-effective. The article briefly describes the technology of each method, and its main strengths and weaknesses, particularly the use and quality of water purification

STUDY OF SORPTION PROPERTIES OF FILTER MATERIALS

abstract 1261702020 issue 126 pp. 266 – 275 28.02.2017 ru 312
Present article is devoted to research of sorption properties of various filtering materials. The various types of filters, such as fabric, frame, granular filters are considered. The principles of work of each type of filters, feature and difference them from each other are considered. The conditions of their application are investigated. Process of filtering through a layer of granular loading also is described. The physicochemical parameters of some granular materials including sand, hydroanthracite-Р, granite road metal, volcanic tuffs, and expanded vermiculite are given. The comparison of oil capacity of some materials is considered at their use as a filtering material and oil collectors. We have described sorption features of activated carbon, used as a filtering material for clearing waters of petroleum and petroleum. The article has a conclusion about their prospects and the efficiency of application when fighting with petroleum pollutions
