Abstract:
1. An apparatus to monitor properties of a slurry to be used in a waste re-injection process, the apparatus comprising: a flow loop in communication with a tank containing the slurry, the flow loop comprising a pump, a viscometer and a densitometer; the viscometer configured to measure a viscosity of the slurry and provide a viscosity output; the densitometer configured to measure the density of the slurry and provide a density output; a controller to receive the viscosity and density outputs and provide an operator interface terminal and system diagnostics; the operator interface terminal in communication with the controller, wherein the operator interface terminal displays the viscosity and density outputs and system diagnostics; a slurry simulator in communication with the controller, the slurry simulator configured to predict performance of an as-injected slurry in the waste re-injection process; the controller configured to perform real-time adjustments to the slurry in the flow loop in response to the predicted performance of the as-injected slurry by the slurry simulator.
