Abstract
An FCC process uses a tube sheet arrangement and a multiplicity of centrifugal separation devices in an FCC reactor to reduce the volume of the reactor vessel thereby minimizing uncontrolled reaction of feed hydrocarbons and the production of riser by-products. The separation arrangement encloses an upwardly directed outlet end of a ballistic separation device in a low volume disengaging vessel that transfers dilute catalyst and product vapors to a tube sheet arrangement of swirl tubes that removes catalyst and directs it downwardly into a stripper arrangement.
