摘要： The present invention provides new techniques for non-invasive and real-time measurement of the velocity profile of slurry flow in horizontal pipes, as well as the measurement and trending of pipe wear on slurry lines. In the first case, this information can be used to determine the approach and onset of solid deposition on the bottom of the pipe. Having this information in real time can enable operation at lower velocities or higher solids concentration or both while avoiding solids deposition or plugging and their associated operational costs. In the second case, the present invention uses a permanently or semi-permanently installed ring of conformable ultrasonic transducers clamped onto the outside of the pipe. These transducers are used to measure the thickness of the pipe under their respective locations.

摘要： The present invention provides a new and unique processor module that features one or more modules configured to respond to one or more input signals containing information about a volumetric flow of a fluid having minerals and varying amounts of entrained gas flowing in a pipe and being processed in a processing stage of a mineral extraction processing system for extracting a mineral from ore, and also configured to provide one or more output signals containing information about operations of the processing stage of the mineral extraction processing system that is not substantially affected by the varying amounts of entrained gas in the fluid flowing in the pipe. The one or more output signals may be used to control the operations of the processing stage. The one or more input signals may be based at least partly on a speed of sound measurement, including a SONAR-based entrained gas measurement to determine the amount of entrained air in conjunction with a density measurement of the fluid flowing in the pipe.

摘要： A signal processor is provided comprising one or more signal processor modules configured to: compare signaling containing information about historical data related to the performance of a pump; and provide corresponding signaling containing information about predicted maintenance needs of the pump on a real time basis based at least partly on the signaling compared containing information about the historical data related to the performance of the pump. The one or more signal processor modules may be configured to compare over time the hydraulic power generated by the pump and electric power consumed by a motor driving the pump, including tracking a ratio of hydraulic to electric power. The one or more signal processor modules may be configured to predict maintenance needs based on an algorithm that takes into account a trade-off between the cost of power consumed by a motor driving the pump and the cost associated with the pump maintenance in order to substantially minimize the total cost of operating the pump.
