ABSTRACT:
A process for separating catalyst particles in the catalytic cracking of reacted hydrocarbons includes feeding the reacted hydrobarbons to an unconfined cyclone device made up of a diplegless cyclone opening directly into a large volume separator vessel downwardly through a mouth and upwardly through the annular space between concentric pipes. The concentric pipes are connected to the other components of the system as well as the hydrocarbon fluid catalytic cracking process carried out in the system.
