A dry thermal processor for recovering hydrocarbons from oil sand solids comprises concentric, radially spaced, horizontal inner and outer tubular members connected for rotation together. The inner member provides a substantially open preheat zone and vaporization zone while the outer member provides, in the annular space between the tubular members, a substantially open combustion zone and heat transfer zone. The ends of the outer member are sealed by stationary feed end and product end structures. Advance means move the oil sand solids from the feed end structure through the preheat and vaporization zones to the product end structure and back through the combustion and heat transfer zones. Rotation of the inner member causes size reduction of the oil sand feed in the preheat zone, and oversize is discharged directly into the annular space at the second end of the preheat zone. Separate means are provided for removing the gases produced in the zones, said means maintaining the gaseous atmospheres in the preheat zone, vaporization zone and annular space substantially segregated from each other.

Apparatus for recovering hydrocarbons from whole oil said containing sand and clay solids in discrete and lump forms, water, bitumen and oversize rocks, said apparatus comprising: spaced, substantially horizontal generally concentric inner and outer tubular members having first and second ends, said members being connected to rotate together, said inner member forming substantially open preheat and vaporization zones at its first and second ends respectively, said members combining to form a substantially open substantially annular space between them having a combustion zone at the second end thereof and a heat transfer zone at the first end thereof; means for supporting and rotating the members; means for sealing the ends of the outer member and the first end of the inner member; means, extending through the sealing means, for feeding whole oil sand into the preheat zone; means, carried by the tubular members, for advancing oil sand solids along a path extending through the preheat and vaporization zones and back through the combustion and heat-transfer zones; said outer member carrying means positioned in the heat transfer zone and adapted to lift hot sand solids being advanced therethrough and to drop them onto a significant portion of the top surface of that section of the wall of the inner member which forms the preheat zone to cause heat to be transferred through such wall section, whereby water in the whole oil sand may be vaporized in the preheat zone and whereby lumps of oil sand may be reduced in size by a combination of heating and cascading effected by rotation of the inner member; first means, extending through the sealing means, for removing water vapor from the preheat zone; means, associated with the preheat portion of the inner tubular member, for separating oversize solids from the whole oil sand being advanced through the preheat zone and transferring them into the annular space for disposal; means, carried by the inner member and extending across the crosssectional area thereof, for restricting gas movement between the preheat and vaporization zones, said means having means in the outer portion thereof operative to permit remaining preheated tar sand to be advanced from the preheat zone into the vaporization zone; means, associated with the inner tubular member, for recycling hot sand solids, being advanced through the annular space, into the first end of the vaporization zone for mixing with oil sand issuing from the preheat zone to raise its temperature and thereby vaporize and crack hydrocarbons and produce coked solids, said means cooperating with the hot sand solids to prevent significant gas movement therethrough between the annular space and the vaporization zone; second means for removing gases from the vaporization zone for recovery; means, associated with the inner tubular member at its second end, for transferring coked solids from the vaporization zone to the combustion zone, said means cooperating with the coked solids to prevent significant gas movement therethrough between said zones; said second means extending through the sealing means and being associated with the coked solids transfer means; means for introducing oxygen-containing gas into the combustion zone for burning coke to produce hot sand solids; third means, associated with the sealing means, for drawing combustion gas from the annular space for disposal; and means, associated with the sealing means, for removing sand solids from the heat transfer zone for disposal.
