Water Requirement For Coal Slurry Transportation, David T. Kao, Sandra L. Rusher
Water Requirement For Coal Slurry Transportation, David T. Kao, Sandra L. Rusher
KWRRI Research Reports
The amount of water required for coal slurry transportation is a function of the coal properties and the magnitude of coal movement. The pipeline system characteristics and the method of slurry preparation also affects the overall water requirement of the system. In the present study methodologies are developed based on reported and modified coal slurry flow correlation equations to determine the quantity of water needed under various coal transport and flow conditions. Auxiliary water requirements including start-up and flushing water storage; related evaporation and seepage losses are also included. A computer program and several monographs are presented to provide a …

Hydrodynamic Separation Of Solids From Solid-Liquid Mixtures, Harry J. Sterling Jr., Don J. Wood
KWRRI Research Reports
Several schemes for separating solid pollutants from water flowing in a closed conduit were examined. Separation based on the momentum differential between the solids and liquids and the centrifugal movement of a conveying liquid were both examined under turbulent flow conditions. The study indicated these processes to have limited applications, primarily due to the difficulties in withdrawing a significant fraction of separated flow and the deleterious effects of turbulent mixing. However, utilization of the differential momentum of solid particles and water when flowing laminarly through a pipe was found to be a viable separation scheme. Significant experimental separations (greater than …
