Centrifuge Polymer Inlet Flow Control
At a Canadian oil sands mining facility, a liquid polymer is injected into the Fluid Fine Tailings (at the centrifuge inlets), separating the fines and clay from the water and expediting the reclamation process. To modulate the polymer media, the client had installed 8” pinch valves.
Due to the incompatibility between the pinch valve sleeve material and the abrasive process media, the sleeves were frequently rupturing. As such, the pinch valves were replaced every month, resulting in significant labor expenditures and lost production.
Disappointed with their pinch valve service life and performance, the client approached SlurryFlo to recommend a better control valve for this application.
A Quantum Leap in Service Life
An 8” SlurryFlo control valve was installed on a trial basis. After two months of service, the client challenged SlurryFlo to further refine the valve’s performance.
Collaborating with the client, SlurryFlo engineers developed a revised seat plate geometry, which further optimized the process control (note: due to SlurryFlo’s unique modular design, the new seat plate was easily installed on site).
Upon one year of service, the client was impressed with SlurryFlo’s control valve service life. They have now replaced all existing pinch valves in this application.
