Abstract
A generally closed vapor path catalytic cracking reactor system is disclosed which includes a vented post-cyclone inertial separator. The inertial separator includes first and second conduit-like members and a vent located at the downstream end of the upstream member. Spent catalyst can be disengaged from a spent catalyst and cracked vapor mixture through the vent while cracked hydrocarbon vapors flow into the second separator member. The separator vent provides a path for stripping gas to enter the generally closed vapor path under routine operating conditions and provides a flow path for damping pressure surges into a surrounding disengagement vessel under transient quality conditions.
