Abstract: The article describes a new design of disc scraping regenerative crystallizer for dewaxing oils and de-oiling slack waxes and petrolatums. To study heat transfer in the crystallizer of this design a computer model of one section of the unit was built. The problem of conjugate heat transfer was solved in a specialized software package based on the numerical finite volume method. The results of numerical simulations, the comparison of the data provided by the developers of the disk crystallizer are presented. The study results showed that the proposed model adequately describes the hydro- and thermodynamic modes of the commercial crystallizer.

The study of nonlinear waves propagation in dispersed hydrocarbon medium
Design, manufacturing and operation of oil and gas sector equipment and facilities

Authors: Alexander F. MAKSIMENKO was born 1954. He graduated from Gubkin Moscow Institute of Petrochemical and Gas Industry in 1976 specializing in “Applied Mathematics”. He is Doctor of Technical Sciences, Professor of the Department of Theoretical Mechanics at Gubkin Russian State University of Oil and Gas. He is author of more than 75 scientific works, including 3 monographs. E-mail: maf@gubkin.ru

Abstract: An equilibrium model describing the propagation of the shock wave through the reacting condensed hydrocarbon medium is constructed. To determine the equilibrium parameters of the condensed hydrocarbon mixture the system of nonlinear equations is numerically solved, includig the thermal equation of state and the generalized law of mass action. The studies carried out using the proposed model are consistent with experimental data. The model allows to assess the degree of conversion of condensed dispersed hydrocarbon compounds during the shock wave at first approximation. It is necessary to know the functions of the standard affinity reactions in this matter, and its coefficient of thermal expansion. A more accurate and detailed analysis of the propagation of the shock wave through the condensed hydrocarbon compounds requires determining their thermal equation of state, as well as building a more correct mathematical model based on the principles of non-equilibrium thermodynamics.

Abstract: The technology for making castings for pump assembly with high surface quality is considered. It is shown that it is possible to manufacture castings of the pump assembly without surface defects using nonstick coatings based on aluminosilicates modified with nanostructured modifier (boehmite). The effect of nano modifiers on the high temperature strength of nonstick coatings is studied. The optimal content of boehmite is shown to increase the strength of nonstick coatings in the temperature range 1000–1500 °C due to the formation of a new phase in the coating, i.e. mullite.

Abstract: The questions of recycling technologies for scarce alloying elements (tungsten, chromium, molybdenum, vanadium, cobalt, etc.) in the manufacture of cast tool and industrial equipment for various purposes, as well as for use as working bodies of drilling and tunneling equipment are considered. The influence of various modifying elements on the physical and mechanical properties of high speed steel is studied. The positive influence of titanium diboride on the impact strength and wear resistance of high speed steel is shown. The effect of cooling rate on the microstructure of high speed steel is studied.

Abstract: Extra-Heavy Crude Oils are interesting for oilmen due the great reserves of this oil type despite deficit of worldwide energy sources. But processing of this type of mineral sources both up-stream and down-stream associated with innovation techniques and the newest apparatus. This work concern to the problems of heavy oil’s treatment by means of electric dehydrators. Particularly implantation into this apparatus dual-polarity electrodes (DPD) should improve the demulsification process which is complicate for heavy crudes by small delta density and small dimension of dispersed droplets. Tests of dehydratation Yarega and Arlan heavy crudes on the models of traditional and DPD dehydrators were carry out to determinate a degree of process intensification. As a result were obtained an equalations that bound the outlet concentration of water in oil with specific load of different apparatus-type and different temperatures. The Viscosity in work conditions of dehydratations was used as a base for coefficient calculation in 3rd degree polynomical equalations. This equalations are the core of new method of electric dehydrators choosing for heavy oils treatment. The applicability of this method was approved by the modernization of refinery and field oil-treatment units in Timano-Pechorskiy oil region. Key words: Extra-Heavy Crude Oil, Field and Refinery Oil Treatment.

Abstract: The values of current density for the economic current density for pricing of 1980 and 2010 are calculated. The calculated values of economic current density are compared with standard values. The spread of economic current densities depending on the price of electricity in December 2010 (by region) and the price of cable products (prices from multiple vendors) is shown. On the example of a typical power supply circuit of gas turbine compressor station a method for selecting the cable line sections using the methods of multi-criterion optimization is proposed. In analyzing this issue, all studies were conducted on the example of the four types of cables: with aluminum and copper conductors, paper and plastic insulation and voltage of 6 kV and 10 kV.
