Abstract:

The article solves the actual problem of determining the value of the critical rate of hydrotransport for a specific hydrotransport unit in terms of its operation in supercritical flow conditions, without violating the process regulations and the required freight traffic for processing. Based on the analysis and generalization of the known methods of calculating the parameters of hydrotransport, a methodical approach was proposed for determining the value of the critical rate of hydrotransportation according to the dependence of the hydraulic slope on the speed and concentration of the slurry. The efficiency of the developed methodology was proved based on the results of measurements of the parameters of the Vilnohirsk State Mining and Metallurgical Plant hydrotransport complex in supercritical conditions. The reliability of the developed technique is confirmed by the fact that the relative error in determining the critical rate of hydrotransport according to the methods improved by the author does not exceed 7 %, and in determining the hydraulic slope does not exceed 6 %, respectively.

Abstract:

This paper presents theoretical considerations and working parameters analyzes of hydrotransport during unstable flow. The variable flow of hydraulic mixture in installations causes unsteady operation and pipes spraying, pump damage, obturation in various sections of the pipeline, reduced capacity as well as higher operating costs. Using mathematical equations presented in this paper, such parameters of the hydraulic mixture, hydrotransport installation and control devices can be determined which protect system from possible clogging. Considering the fact that critical speed of hydraulic mixture depends on transported material grain size, mixture volume mass, diameter of pipeline and specific gravity of solid phase, it is possible to accurately analyze obturation in hydrotransport installations depending on those parameters. In order to prevent hydraulic impacts in hydrotransport installation pipelines, which value can be determined mathematically, it is necessary to adjust installation to hydromixture parameters and pump, or vice versa.

Abstract:

The method of determination of parameters of hydrotransport of solid polydisperse materials in vertical pipelines is offered. The reasons of discrepancy between estimated and observed data when using A. Smoldyrev’s method for calculation of hydraulic gradient and critical velocity in vertical steel pipelines are analysed. Particularly non-applicability of Velicanov principle to hydrotransport of solid materials in vertical pipelines is proved and contribution of particles fall velocity to the value of complementary hydraulic gradient in vertical pipelines is estimated. Suggested formulas for calculation of hydraulic gradient and critical velocity in vertical pipelines are multipurpose because they may be used for calculation of hydrotransport parameters in steel and polymeric vertical pipelines with using of friction reducing agents and without it. The method for parameters calculation of solid materials hydrotransport in vertical polymeric pipelines is first offered. Elaborated formulas ensure also increasing of accuracy of calculations.

Abstract:

The effect of slurry conditioning on bitumen recovery and bitumen froth quality has been studied by using three oil sands ores tested with a laboratory hydrotransport extraction system (LHES) and a Denver flotation cell. Tests with the LHES show that an increase in slurry conditioning time yielded a lowered bitumen recovery for a long flotation time (30 min). Longer slurry conditioning time led to a better bitumen froth quality regardless of flotation time. However the over conditioning could be compensated by higher conditioning temperatures and higher slurry flow velocities. Tests with the Denver flotation cell show that the increase in slurry conditioning time resulted in a higher bitumen recovery and a better bitumen froth quality for both good and poor processing ores for a shorter flotation time of 5 min. For a longer flotation time of 20 min, increasing slurry conditioning time had little impact on bitumen recovery but led to a slightly better bitumen froth quality for the good processing ore whereas no effect on bitumen froth quality of the poor processing ore. Results also show that higher slurry temperatures and stronger mechanical energy input were beneficial to both bitumen recovery and bitumen froth quality for all three oil sands ores tested on both devices.

Abstract:

In the present work the generalized mathematical model (SK model) developed by Shrivastava and Kar [1, 2] has been utilized to determine the optimum size of the solid particles (sand, coal, pvc- granules, and lead shot), which offers the minimum frictional resistance to flow and results into the minimum head loss when transported through horizontal pipes under the conditions identical to those achieved by the investigators [3- 6] in their experiments. On the basis of the present investigation it has been observed that for the transport of solid through horizontal pipe at constant throughput the head loss does not depend directly on the size of the particles rather it depends on the values of the critical velocity (fluid velocity at which the head loss is minimum in the characteristic curve) calculated for solids of different sizes. Whereas for the transport of solid particles at constant volumetric concentration the head loss depends directly on the size of the particle and it is minimum for the largest size of the particle. Thus, it is possible to determine the optimum size of the particles for economical hydrotransport through horizontal pipe at constant throughput from the energy consumption point of view by utilizing the expressions of SK model.

Full text

Abstract:

Different flow pattern maps and theoretical models were employed to determine the flow velocity needed to provide the dispersed-bubble flow in a hydrotransport pipeline. Comparison and analysis of the results has been carried out. The maximum and minimum bubble sizes were determined by semi-experimental methods. A log-normal function was employed to describe the bubble size distribution. A model for the bubble size change in the turbulent pipe flow was applied to study the evolution of the overall bubble size distribution. This model takes into account the competing factors influencing the bubble size: 1) dissolution (turbulent diffusion) of air in the liquid, causing bubble shrinkage; 2) pressure drop along the pipeline, causing bubble growth. Numerical analysis shows that the bubble dissolution rate strongly depends on the initial air hold-up and initial bubble size. An increase of air hold-up leads to a fast decrease of the dissolution rate. At sufficient high air hold-ups, the dissolution effect becomes negligible and air bubble sizes are dominantly controlled by the pressure drop. Smaller bubbles have higher dissolution rates than larger ones. Compared with a pure liquid flow under the same flow conditions, the effect of air hold-up is stronger in the slurry flow because of the smaller volume occupied by the liquid.

Abstract:

Erosion-corrosion (E-C) of X-65 pipe steel was investigated in a simulated oil sand slurry through an impingement jet system. Measurements of weight-loss and potentiodynamic polarization curves combined with optical microscopy observation were performed to determine the synergism of corrosion and erosion in E-C of steel. It was found that passivity of the steel developed in static oil-water emulsion cannot be maintained in the flowing fluid due to the enhanced activity of the steel upon impingement of the emulsion/slurry. The effect of slurry impact angle on E-C of steel is complex, depending on the magnitude and synergism of shear stress and normal stress exerting on the electrode surface. There is a synergism of corrosion and erosion in E-C of steel. The contributions of corrosion and erosion to E-C rate of the steel in oil sand slurry rank approximately 30% and 70%, respectively. Erosion dominates the E-C of X-65 steel in oil sand slurry.

Abstract:

Preliminary work has been completed to investigate the effect of particle-particle interaction forces on the flow properties of silica slurries. Classically Hydrotransport studies have focused on the flow of coarse granular material in Newtonian fluids. However, with current economical and environmental pressures, the need to increase solid loadings in pipe flow has lead to studies that examine non-Newtonian fluid dynamics. The flow characteristics of non-Newtonian slurries can be greatly influenced through controlling the solution chemistry. Here we present data on an “ideal” slurry where the particle size and shape is controlled together with the solution chemistry. We have investigated the effect of adsorbed cations on the stability of a suspension, the packing nature of a sediment and the frictional forces to be overcome during reslurrying. A significant change in the criteria assessed was observed as the electrolyte concentration was increased from 0.1mM to 1M. In relation to industrial processes, such delicate control of the slurry chemistry can greatly influence the optimum operating conditions of non-Newtonian pipe flows.
