ABSTRACT:
Disclosed is a process and apparatus for reducing the particulate content in a gaseous stream containing entrained particulate matter and condensable hydrocarbons wherein said stream is obtained from the retorting of hydrocarbon-containing solids, particularly from retorted shale. A gaseous effluent containing condensable hydrocarbons and entrained solid particulate matter is produced during the retorting of hydrocarbon-containing solids and is discharged from a retorting vessel through a conduit containing a rotating elongate spiral-shaped element on which a portion of the particulate matter and condensable hydrocarbons form a semi-solid mass. The rotating spiral collects and conveys the semi-solid mass back into the retorting vessel for further processing thereby reducing the solid particulate content of the condensable hydrocarbon product.
