Abstract
An inertial/filtering separator in a single vessel and FCC process using same as a third stage separator are disclosed. Gas and fines are added tangentially to an annulus formed by a cylindrical insert in a vessel. Gas flows over the insert and down to filters in the vessel. Solids are withdrawn from the base of the annulus and periodically from the filter. Three types of solids collection--inertial, gravity settling and filtration--are practiced in a single vessel.
