Abstract
An apparatus for recovery of solids from a vapor, the apparatus including: a vessel comprising a cylindrical portion on top of an angled portion; a vapor inlet located in the cylindrical portion for introducing a solid-vapor mixture tangentially to the cylindrical portion; at least one inlet nozzle disposed in a top of the vessel for spraying a hydrocarbon fluid into the vessel; an indirect heat exchange device disposed concentrically within the cylindrical portion, thereby providing an annulus for vapor and hydrocarbon flow; a heat exchange device disposed at an exterior of the angled portion; an outlet located at a bottom of the angled portion to recover the vapor having a reduced solids content and a solid-hydrocarbon mixture. Also disclosed are processes to clean an oil vapor using such an apparatus.
