Abstract:
Method and apparatus to facilitate recycling of at least one fraction of bitumen-containing materials. This can be accomplished by dissolving the at least one fraction, for example, maltenes or asphaltenes in roofing shingles, into at least one solvent. In one aspect, the apparatus comprises a dissolution vessel, a tumbler positioned therein, and at least one solvent distributor. The tumbler is configured to facilitate wetting the bitumen-containing materials with solvent. In a second aspect, a system comprises the apparatus, a solid-liquid separator, for example, a vibratory screen, and at least one solvent-fraction separator, for example, a flash drum. The at least one solvent can comprise one or more solvents useful to extract the at least one fraction. In a third aspect, a first fraction is extracted from the bitumen-containing materials with a first solvent composition, then a second fraction is extracted from the remaining bitumen-containing materials with a second solvent composition.

Claim (Index 1):
An apparatus to facilitate dissolution of at least one fraction of bitumen-containing materials into at least one solvent, the apparatus comprising:\n a dissolution vessel; a tumbler configured to agitate the bitumen-containing materials and facilitate wetting the bitumen-containing materials with the at least one solvent; and at least one solvent distributor configured to discharge the at least one solvent into the dissolution vessel;\n wherein the dissolution vessel comprises: \n a feed inlet of the dissolution vessel configured to facilitate feeding the bitumen-containing materials into the dissolution vessel; \n a catch basin of the dissolution vessel; and \n at least one discharge outlet of the dissolution vessel; \n wherein the tumbler comprises:\n a cage configured to rotate within the dissolution vessel and to receive the bitumen-containing materials, wherein the bitumen-containing materials comprise larger solid objects and smaller solid objects, wherein the cage is configured to partially contain the bitumen-containing materials, wherein the cage comprises cage apertures configured to retain the larger solid objects that cannot pass through the cage apertures and allow liquid and the smaller solid objects to pass through the cage apertures; and \n a containment space bounded by the cage, wherein the containment space is configured to permit the bitumen-containing materials to be agitated within the cage; \n wherein the catch basin is configured to receive catch basin contents, wherein the catch basin contents comprise the at least one solvent, the at least one fraction of the bitumen-containing materials and the smaller solid objects in the bitumen-containing materials, and wherein the catch basin is configured to discharge the catch basin contents through the at least one discharge outlet, thereby providing a mixed-materials stream.
