Process for stripping and a fluid catalytic cracking apparatus relating thereto

A fluid catalytic cracking apparatus, comprising:

• A) a stripping vessel forming an inner circumference;
• B) a riser received within the stripping vessel and forming an outer circumference wherein the inner circumference and the outer circumference define an annular zone;
• C) one or more packing layers positioned within the annular zone;
• and
• D) a plurality of baffles, comprising a first baffle and a second baffle positioned below the one or more packing layers.

A process for stripping, comprising:

• A) passing catalyst to a stripping vessel wherein the stripping vessel forms an interior area defined by an inner circumference of the stripping vessel;
• B) providing a plurality of baffles comprising a first baffle and a second baffle wherein the first baffle is positioned within the stripping vessel spaced apart from the inner circumference and the second baffle is coupled to the inner circumference and extends inward into the interior area;
• and
• C) providing one or more packing layers above the plurality of baffles.
