Apparatuses for separating catalyst particles from an fcc vapor

An apparatus for separating solid catalyst particles from a Fluid Catalytic Cracking (FCC) vapor comprising:

• a conduit defining an axis and configured to direct flow of an FCC vapor-solid stream in an axial direction;
• and
• four channels in fluid communication with the conduit and configured to receive the FCC vapor-solid stream from the conduit, wherein each 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 respective inlet cross-sectional area, wherein each channel inlet is coupled to the conduit, and wherein each channel outlet is configured to direct the vapor-solid stream tangential to the axis.

An apparatus for separating solid catalyst particles from a Fluid Catalytic Cracking (FCC) vapor comprising:

• an FCC vessel formed with a vessel wall;
• a conduit configured to direct flow of a vapor-solid stream, wherein the conduit is positioned within the vessel;
• a channel positioned within the vessel and having a channel inlet in fluid communication with the conduit and a channel outlet configured to direct flow of the vapor-solid stream tangentially toward the vessel wall, wherein the channel includes means for accelerating the flow of the vapor-solid stream out of the channel outlet and for separating the solid catalyst particles from the FCC vapor.
