Abstract
Apparatuses for separating solid catalyst particles from a Fluid Catalytic Cracking (FCC) vapor are provided. In one embodiment, an apparatus includes a vessel formed with a vessel wall. A conduit is positioned within the vessel and is configured to direct flow of an FCC vapor-solid stream. The apparatus also includes a channel positioned within the vessel and in fluid communication with the conduit. The channel has a channel inlet with an inlet cross-sectional area and a channel outlet with an outlet cross-sectional area less than about 75% of the inlet cross-sectional area. The channel outlet is configured to direct the vapor-solid stream tangentially toward the vessel wall to separate the solid catalyst particles from the FCC vapor.
