Zusammenfassung:A method for monitoring and controlling flocculation of oil sands fine tailings in a pipeline is provided comprising injecting a polymeric flocculant into a tailings feed being pumped through the pipeline, mixing the polymeric flocculant and tailings feed in the pipeline, and providing one or more adjustable valves in the pipeline that are operable to either reduce the flow area of the adjustable valve to increase shear or dispersed energy when the polymeric flocculant and tailings feed are under-mixed or increase the flow area of the adjustable valve to decrease shear or dispersed energy when the polymeric flocculant and tailings feed are over-mixed.
