Abstract: A feedwell is provided for an inclined plate separator having a separation chamber containing parallel plates defining separation passages. The feedwell includes a plenum defining a plenum chamber external to the separation chamber, an upward-facing deflector surface in the plenum chamber, an inlet for discharging influent fluid onto a receiving region of the deflector surface, and an outlet for discharging the influent fluid out of the plenum and transversely into the separation chamber. The feedwell also includes parallel fins. The fins define between them plenum passages that extend from a fin end to outlet. The fin ends are disposed between the outlet and the receiving region, and are arranged in a horizontal semi-elliptical path defining a center that horizontally coincides with the receiving region.

Abstract: The liquid feed nozzle assemblies for a circulating fluid bed reactor comprise (i) a throttle body premixer to combine liquid feed with atomization steam to form a liquid feed/steam mixture comprising gas bubbles in liquid; (ii) a conduit connected to the premixer and to a discharge nozzle to convey a flow of the liquid/steam mixture created by the premixer to the nozzle body; (iii) a discharge nozzle connected to the flow conduit to shear the liquid feed/steam mixture to create liquid feed droplets of reduced size and (iv) a disperser at the outlet of the discharge nozzle to provide a spray jet of liquid feed having an increased surface area relative to a cylindrical jet. The nozzle assembles are particularly useful in fluid coking units using heavy oil feeds such a tar sands bitumen.

Abstract: A feedwell system for use in a separation vessel is provided, comprising a substantially cylindrical chamber having a bottom floor with an opening therein; an inlet for introducing a feed stream into the substantially cylindrical chamber; and a deflector plate having a generally conical shape and spacedly position beneath the opening of the bottom floor, the deflector plate having at least one aperture therethrough; whereby the feed stream exits the opening of the bottom floor onto the deflector plate having at least one aperture therethrough.
