FLOCCULATED OIL FINE TAILINGS DEPOSITION METHOD AND DEVICE

摘要

A method and device for additionally mixing mature fine tailings (MFT) with flocculating agent prior to depositing into a deposition cell. The method includes the steps of: a) receiving a fluid flow of flocculated mature fine tailings and residual flocculating agent from an in-line feed; b) reducing the flow velocity of the fluid flow and accumulating it inside a chamber up to a predetermined height; and c) allowing the fluid flow to flow down a descent assembly so as to descend from the predetermined height to at least one lower height, the descent assembly being configured so that residual flocculating agent from the fluid flow is additionally mixed with mature fine tailings from the fluid flow when it travels down the descent assembly from an upper region to a lower region, the descent assembly being further configured for preventing overshearing of the flocculated mature fine tailings. Also disclosed is a kit with corresponding components for assembling the deposition device.
