Abstract
A multi-stage cyclone for fluidized catalytic cracking of heavy oils is disclosed. A low efficiency inertial separator concentrates solids, FCC catalyst and fines, by forcing gas and entrained solids to make from 1/2 to 3/4 turn. Gas, with most of the solids content removed, is charged directly into the inlet horn of a conventional high efficiency cyclone. The solids concentrator/cyclone device may be used in FCC regenerators or reactors to reduce particulate losses, reduce catalyst attrition, and reduce erosion of cyclones caused by high catalyst loadings.
