Abstract
A separator apparatus has been invented which rapidly disengages catalyst from product vapor in the reactor discharge stream of a fluid catalytic cracking (FCC) apparatus. The separator apparatus comprises a flow diverter which comprises a frustum in which are spiral channels which induce a spin on the impacting stream and are sufficiently deep to contain a layer of catalyst. A position member is attached to the frustum base and apertures in the position member allow the flow of vapor to a bore and on to cyclone separators where final catalyst-vapor separation is made. Catalyst does not pass through the apertures and remains within a cylindrical separation chamber in flow communication with a dip leg which directs the catalyst to a stripper vessel in the fluid catalytic cracking apparatus. The separator apparatus is a solution to the vibration problem experienced in the use of rough-cut cyclones.
