A flow loop that contains a mixing tank, pump, horizontal pipeline, and corresponding measurement transducers has been constructed at Florida International University's Hemispheric Center for Environmental Technology (FIU-HCET). Several slurry simulants that include liquid and five or six chemical solid species were applied in the tests. New data were provided on the pressure gradient and volume concentration across a vertical cross-section. It was found that the flow characteristics are quite distinct from the classical characteristics of coal-water or sand-water slurry flowing in horizontal pipelines. An apparent transition point occurs in the curve of the pressure gradient versus velocity. Flow observation identified that the solid particles settle down at the velocities of the corresponding transition points. The velocities at the transition points are classified as the limit deposition velocity. Lower velocity than the limit deposition velocity will result in a stationary bed flow. Weight concentration measurements in a heterogeneous flow regime indicate that there is no weight concentration gradient along the axial distance. However, within the present parameter range, the weight concentration is always higher at the top point than that at the bottom point.
