System to separate suspensions of catalyst particles and reacted mixture of hydrocarbons

摘要

A system for separating catalyst particles in the catalytic cracking of reacted hydrocarbons includes 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.
