Abstract: Paunch-sludge from an abattoir is mixed with the fatty DAF-float from an abattoir, and placed in a shearing vessel. The mixture of the two material thickens the medium in which the matted strands are contained, enabling shearing to be more effective; so much so that paunch-sludge can now be sheared to a homogeneous liquid. The technique can be used with other sludges and other fatty waste materials.

Abstract: A system for chemically disposing energetic material enclosed in assembled devices includes a porous basket. The porous basket forms an enclosed chamber for receiving the assembled devices. Further, the basket is supported by a rotatable basket arm that is, in turn, connected to a lifting arm. In addition to these structures, the system includes a tank that holds a hydrolysis solution.

Abstract: A method and apparatus are provided for removing oil from absorbent materials of the type used in components for absorbing oil and containing oil spills. The components are first passed through a press to squeeze some of the oil from the components. The components are then shredded to separate the components into separate pieces of the absorbent materials. An auger pushes the pieces of absorbent materials into an elongated tubular trommel having a perforated sidewall. The pieces of absorbent materials are sprayed with treatment fluids as the trommel is rotated to tumble the absorbent materials within the trommel. The oil and treatment fluids drain from the absorbent materials, and pass through the perforations in the trommel sidewalls and onto a collection trough. The collection trough directs the oil and treatment fluids through a separator to reclaim treatment fluids and oil for later use.

Abstract: The washer comprises an open-topped vessel having a tube mounted vertically and centrally therein. Post-primary bitumen froth is fed to the upper end of the tube. Pairs of down throw and up throw propellers mounted to rotate in the tube act to shear the froth as it passes down through the tube. At its lower end, the tube is closed off by a transverse wall. Slots are formed in the tube side wall to provide an exit. The sheared mixture thus changes direction as it leaves the tube. In the vessel chamber, solids and water sink downwardly and are removed as tailings through a bottom outlet. The sheared aerated bitumen rises and forms a new forth that is recovered in a launder. Middlings are withdrawn from the chamber and recycled to join the feed. The product froth is reduced in water and solids relative to the feed froth.

Abstract: In a reactor, granular feedstock having particle sizes in the range from about 0.5 to 15 mm is subjected in a moving bed to a countercurrent extraction at a temperature in the range from 20.degree. to 150.degree. C. and under a pressure in the range from 50 to 400 bars by a continuously supplied solvent which is in a liquid or supercritical state. A mixture of valuable substances and solvent is withdrawn from the upper portion of the reactor. The solvent is separated from the valuable substances by a pressure relief and/or temperature rise and is recycled to the reactor. The extraction residue is withdrawn from the lower end of the reactor. Respective locks are used to charge the feedstock into the reactor and to discharge the extraction residue from the reactor. Solvent and an entrainer are supplied to the reactor at different locations. Outlet ducts having a length of 0.1 to 1 m are preferably used to deliver the feedstock onto a moving bed in the reactor so that a free space is provided over the bed.

Abstract: The thermodynamic efficiency of a tar sands conditioning drum is improved by continuously and simultaneously discharging steam from all the nozzles of an array of a few relatively large nozzles distributed circumferentially around the inner drum periphery rather than selectively sparging the steam only from those nozzles beneath the tar sands pulp surface. As a result, the drum shell and components above the pulp are heated and thus heat the pulp by radiation and, after entering the pulp, by convection as well as by sparging. Hot water droplets formed continuously in the steam cloud rain onto the pulp surface to provide another highly important heat transfer mechanism. Coincidentally, mechanical reliability and economics are achieved by eliminating the sparge valve and multiplicity of smaller nozzles which characterize the prior art tar sands conditioning drums.
