  • Technical solutions for treatment of underground waters containing hydrogen sulfide

    The article describes the chemical composition of groundwater in the Rostov area. On the basis of sanitary and environmental assessment of the chemical composition of groundwater from wells, one of the areas of the South-Eastern part of the Rostov area, which are sources of water of the Egorlykskaya station, it was found that the concentration of hydrogen sulfide exceeds the MPC by about 1000 times. Analysis of methods of water purification from hydrogen sulfide, the main of which include: oxidation with molecular chlorine, sodium hypochlorite, hydrogen peroxide, showed the advantage of using the hydrogen peroxide. A new reactor design is proposed, which allows to increase the contact time of the treated water with the oxidant by hydrogen peroxide without increasing the size of the structure. This allows the maximum transfer of dissolved hydrogen sulfide in the solid phase.

    Keywords: groundwater; hydrogen sulfide, purification, hydrogen peroxide, chemical reactor, economic efficiency

  • New directions of research and development in the field of nanotechnology for the creation and application of inorganic composite materials Part I

    In the paper, we give a brief overview of the main developments made personally and under the direct supervision of the professor, academician RANS andIAELPS P. Kudryavtsev. These developments are devoted to the use of sol-gel processes in various branches of science and technology. Using this process, new composite heat-resistant materials, highly disperse materials and thin filmswere created. These developments have made it possible to create new efficient catalysts and highly selective inorganic ion-exchange materials. Based on inorganic ion-exchange materials, a technology was developed to extract lithium from natural brines, which are poor in lithium content. On the basis of sol-gel technology, new composite matrix-isolated flocculants-coagulants were created. These reagents are designed for the treatment of natural and wastewater in order to remove impurities of oil products and heavy metals.

  • Methods for evaluating the operational reliability of cars

    The study on the hardness of samples from steel ST3 and 15G. On the basis of the correlation equations obtained values of ultimate strength of the examined steels. With the application of the law of three-parameter Weibull distribution constructed density distribution and the resulting minimum value of ultimate strength. The obtained results are proposed to use to determine the value of the resource for load-bearing systems of vehicles.

    Keywords: reliability, lifetime, the hardness of steel, strength of steels, the endurance limit of steels, the Weibull law

  • Simulation modeling as a tool for integrated assessment of strategic risks logistics companies

    The possibility of improving the management efficiency of the main business processes of a logistics enterprise on the basis of an integrated assessment of strategic risks is considered. The methodology is based on the idea of sharing the technology of simulation and two concepts: the Balanced Scorecard (BSС) and the Integrated Risk Management System (IRMS). We propose formula for calculating operational risk based on port statistics collected while running the simulation model, namely the chosen values of the triangular distribution of the statistical data. Also presented a formula linguistic evaluation of integrated strategic risk, lead to the conclusion the risk that previously designated port strategy will not be achieved.

  • Determination of degree of homogenization of composition mixtures based on estimation of entropy of optoleptical information obtained by mixture surface photosensitive scanning

    In this article we consider technique of determination of degree of homogeneity of heterogeneous mixtures by using tool contactless method. This method uses optoleptical information of mixture surface. This method can be used in automatic control systems. An optoleptical information may be obtained using standard devices of photosensitive scanning. The value of entropy of otptoleptical information is used to estimate the degree of mixture homogenization. Operations of component mixing are widely used in technological processes. The degree of homogenization of mixture is the one of quality indicators of mixing process. The degree of homogenization is usually determined by laboratory method, which requires additional time for analysis. The degree of homogenization can also be determined by using the senses. In this case, the results of determination depends on the experience of the expert. In this article we looked at an example for the paint industry. The method can be applied to a wide range of heterogeneous composition.
