ABSTRACT:
A rough cut catalyst/vapor separator for fluid catalyst cracking risers which is located at the outlet of a riser and causes the oil-catalyst mixture to undergo a tight, 180 degree downward turn. The centrifugal separator is equivalent to one-half a turn inside a cyclone and causes most of the catalyst to move to the wall. Most of the oil vapors are squeezed out away from the wall. At the end of the separator is a shave-off scoop positioned to divide a predominantly catalyst phase from a predominantly oil phase. The shave-off scoops conduct the catalyst phase away from the center of the vessel and deposit it near the vessel wall where its downward flow is continued under the action of gravity. The oil vapor phase continue its downward flow for a while but then must undergo a 180 degree turn and flow upward to exit the vessel through a series of conventional cyclone separators. The second 180 degree turn of the oil vapors help separate catalyst which is not caught by the shave-off scoop.
