摘要
A riser cyclone separator is positioned external to a containment vessel. The riser cyclone separator discharges separated catalyst to a catalyst stripper and separated vapor to a plenum, both positioned internal to the containment vessel. Means is provided for withdrawing stripping gas from the catalyst stripper and passing it via the riser cyclone separator to the plenum. The riser cyclone separator is inherently pressure stable relative to the containment vessel. The invention is particularly useful for retrofitting a direct-connected riser cyclone separator to a preexisting containment vessel with space limitations.
