    Springer
    Details
    Publikationsdatum: 2014-12-19
    Beschreibung: It is established that carbonate dissolution kinetics have diffusion and kinetic control, i.e., chemical reaction rate determines the transfer of calcium and carbonate ions into solution and diffusion processes determine the removal of ions into the depth of solution. Kinetics of calcite and siderite dissolution in hydrochloric acid solution in relation to medium pH are studied. Orders of dissolution reaction rate with respect to hydrogen ions n (H + ) = 0.6±0.1 are calculated.

    Beschreibung: A mathematical model of physical and chemical processes that occur during solid-fuel gasification in a fluidized bed reactor is defined. The physical and chemical processes in the reaction zone of the gasifier are analyzed. A basic system of differential equations of continuum mechanics for a multiphase flow with consideration of heat and mass exchange, turbulence, and chemical reactions within the effective space of the gasifier are formulated. The physical equations of state of the medium and algebraic equations for calculation of the coefficient of exchange between the solid particles and gas flow are presented. The kinetic rates of the chemical reactions in the gasification process are defined. The mathematical model proposed is required for numerical analysis of physical fields of the gasifier, and optimization of its operation with maximum hydrogen yield in the synthesis gas.

    Beschreibung: Results of hydrodynamic tests of dry and irrigated polymer miniring nozzles 40 ∞ 3.5 ∞ 1 mm in dimension are presented. It is shown that MRN-type nozzles surpass foreign counterparts in terms of basic geometric characteristics. Thus, the specific surface of an MRN-type nozzle is 180 m 2 /m 3 , i.e., 40% higher than that of the well-known CMR nozzle. Tests demonstrated that the hydraulic resistance of a dry MRN-type nozzle is one-third that of a nozzle made of Raschig rings and 1.3-times less than that of a CMR nozzle. Empirical equations for use in determining hydraulic resistance are presented.

    Beschreibung: The distinctive features of contact interaction between seat and wedge in gate valves are investigated using a finite-elements analysis program. It is shown by the example of DN400 valve that the forces of interaction between the seat and the wedge are unevenly distributed over the area of their contact. To avoid failure, the forces of contact interaction must not be excessively large. However, weakening of contact interaction increases the risk of loss of leak-tightness of the seat–wedge junction.

    Beschreibung: This article evaluates 440 standard sizes of separators for the oil and gas industry. The author proposes an evaluation and selection method for oil and gas collection, transportation, and processing plants. Weight and size parameters of the separators depend on the type of machine, projected consumption of gas and liquid, and operating pressure. The parameters can vary by an order of magnitude for the separators of one type, and by two orders of magnitude for separators of different types. The aforesaid method of selection by separation efficiency and weight and size criteria is recommended for selection of separators in the oil and gas and other industries.

    Influence of Nonuniformity of Gas Flow on Efficiency of Gas Cleaning in an Electrostatic Precipitator (2014)
    Springer
    Details
    Publikationsdatum: 2014-04-06
    Beschreibung: Based on an analysis of Deitsh’s formula, which relates the velocity of a gas in an electrostatic precipitator to the magnitude of the overshooting through the apparatus, it is established that the optimal velocity of the flow in an electrostatic precipitator corresponds to the minimum of the second derivative, i.e., 50–60% above the velocity corresponding to the inflection point. It is shown that, depending on the length of the active zone of an electrostatic precipitator, the nonuniformity of the flow may lead to a decrease in the overshooting of 10% and more. On the basis of the results obtained, a gas-distributing lattice mounted in a converging tube that creates nonuniformity in the active zone of the terminal field of the electrostatic precipitator is developed.

    Capabilities of Theoretical and Empirical Methods of Calculating the Parameters of Viscous Flow of a Medium in Cylindrical Annular Channels (2014)
    Springer
    Details
    Publikationsdatum: 2014-11-22
    Beschreibung: Questions related to the selection and application of theoretical or empirical methods for the calculation of the parameters of the groove seals of shafts widely used in pumps and compressors are considered. A theoretical method of calculation through the compilation and solution of a system of equations that describe the flow of a medium in the channel of a groove seal is successfully applied for the case of a laminar regime of flow of a medium in a channel. It is not possible to describe such flow by means of a closed system of equations in the case of a turbulent regime of flow of a medium in the channel of a groove seal. The new theoretical method of determining the unknown parameters of the turbulent flow of a medium in annular groove seals, which is related to the solution of the Martsinkovskii equation, may serve only as a tool for studying the nature of the processes that occur in a groove seal. Thus, empirical methods based on Bernoulli’s equation and the data of experimental investigations are still the only reliable tool for calculating the characteristics of groove seals in the case of a turbulent regime of flow of a medium.

    Beschreibung: The combustion of distillate fuel by single steel particles of fixed size and a massive “hot” metal plate are investigated experimentally. It is possible to conclude that significant differences exist between the heat-transfer conditions at ignition of liquid fuels by a massive heat source and a small-size single heated particle on the basis of analysis and codification of results of the experimental investigations conducted. Experimentally determined thermokinetic ignition parameters of the liquid fuels will also differ appreciably. The results obtained from the experimental investigations are the basis for further development of ignition models of hot liquids, particularly detailed accounting of heat-and mass-transfer processes.

    Optimization of Flow Diagrams of Multiphase Pump-Ejector Systems for Improving Their Operational Efficiency with Combined Oil and Gas Gathering (2014)
    Springer
    Details
    Publikationsdatum: 2014-11-21
    Beschreibung: It is shown that the primary cause of inefficient operation of multiphase pump-ejector systems installed in oil fields for combined oil and gas gathering is that not only associated (casing-head) gas, but also oil recovered incidentally with water enters the receiving chambers of jet apparatuses. Even under the current operation conditions, the power consumption at BPS-0122 Sofinskaya booster-type pumping plant can be reduced more than twofold by utilizing the existing infrastructure to the maximum and optimizing the flow diagrams of the pump-ejector system where the functions of submersible centrifugal pumps and jet apparatuses are separated. In future development, the pump-ejector system could be provided with an additional ejector, which will allow effective integration of straight-flow and circulatory schemes.

    Modeling the Gravity Cascade Classification of Granular Materials (2014)
    Springer
    Details
    Publikationsdatum: 2014-11-21
    Beschreibung: A schematic of a gravity cascade classification of granular materials is suggested. A mathematical model is developed for the distribution dynamics of particles of a targeted component throughout the stages of a cascade gravity classifier under the action of mixing, segregation, and migration effects in a gravity flow of a granular material. Cascade gravity classification is mathematically modeled and the results obtained are compared with experimental data. The adequacy of the modeling results is confirmed by assessing the uniformity of adequacy and reproducibility dispersions.

    Specifics of Separator Work at Low Gas Flow Rates (2014)
    Springer
    Details
    Publikationsdatum: 2014-11-21
    Beschreibung: A procedure for calculating work of several separators having string, mesh, and centrifugal heavy-phase (liquid) precipitators (HPP) at low gas flow rates, when separation in the HPP takes place in the gravity precipitation mode in the separator gas zone, is described. In this process, specific liquid entrainment with the gas increases dramatically. In selecting separators, if the factor of gas velocity in the HPP is less than the minimum calculated level, a correction must be made in the calculation and design of the separators. During operation of the separators, the actual gas flow rate and pressure should be checked to find out whether the gas velocity factor in the HPP fell below the minimum calculated level, and this should be taken into account in calculating liquid entrainment with the gas.
