Abstract

A cyclone (500) suitable for use in a third stage separator in a fluid catalytic cracking unit or to improve other gas/solid separations. The cyclone has an inlet for gas and entrained solids (515) and a clean gas outlet tube (520) at one end of a cyclone body. Solids and some gas are withdrawn through a solids outlet (545) and discharged into a catch chamber. Some of the gas discharged with the solids into the catch chamber is returned to the interior of the cyclone body through a gas reflux opening in the cyclone (555). Chaotic reflux of gas back into the cyclone through the solids outlet is eliminated.
