A feedwell system for delivering a slurry (for example a bituminous slurry) to a separation vessel (for example a primary separation vessel) includes a feedwell barrel with an inlet for receiving the slurry, internal baffles, and a bottom outlet. A downpipe extends from the bottom of the barrel directing the existing slurry onto a deflector plate deflecting the slurry radially and outwardly. A protector plate located between the downpipe and the deflector plate improves the underwash layer stability. Ventilation openings in the protector plate induce inflow which reduces the discharge velocity, limits the formation of an adverse pressure gradient and encourages circumferential distribution.

Feedwell system for a separation vessel

A feedwell for a gravity separation vessel for introducing a feed stream such as oil sand slurry to the gravity separation vessel is provided comprising a walled member having an upper perimeter edge, a lower perimeter edge and a substantially continuous wall extending from the upper perimeter edge to the lower perimeter edge; an inlet for introducing the feed stream into the walled member positioned adjacent the substantially continuous wall; and a bottom floor having an opening and extending generally beneath the lower perimeter edge; whereby a perimeter of the opening is less than a perimeter of the walled member.
