Abstract
Induction loss systems are used in mining for process control in long-distance pumping, aiming to maintain appropriate pressure levels and control flow. However, these systems dissipate energy, which increases the pumping system's consumption. This work proposes the use of pressure control systems at dissipation points to recover part of this dissipated energy through pumps operating as turbines (PAT), thereby reducing the overall operational cost of the asset. Additionally, PATs allow for continuous control in slurry systems that cannot be controlled by valves due to the material's abrasiveness. An instrumented loop pumping system was developed and constructed to test the proposed system on a reduced scale.
