Title:
APPARATUS FOR RECOVERING HYDROCARBONS FROM SOLIDS
Document Type and Number:
WIPO Patent Application WO1998035767
Kind Code:
A3
Abstract:
An apparatus is provided which is a trailer mounted rotating drum having an auger feed, an air tight seal, chain, and spiral and lateral flights within the drum which is heated externally, through which contaminated soil, such as drilling cuttings, is heated and processed to remove and reclaim the contaminants. The decontaminated soil exits through a dual trap door arrangement with the entry and exit door being 180 DEG apart. A water quench line extends into the drum for dust suppression. The contaminant is typically diesel oil which has been added to drilling muds. The soil which exits the unit is essentially contaminant free, and the diesel oil which has been vaporized during the heating process is condensed and collected.
