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):
A method for separating bitumen-containing materials to provide at least one product stream, wherein the bitumen-containing materials comprise a first fraction and a second fraction, and wherein the at least one product stream comprises a first-fraction-rich stream comprising the first fraction and a second-fraction-rich stream comprising the second fraction, the method comprising:\n contacting the bitumen-containing materials with a first solvent, wherein the first fraction is soluble in the first solvent, and wherein the first fraction comprises maltenes; separating the bitumen-containing materials to provide a first-solvent-and-first-fraction-rich stream and a first remaining portion of the bitumen-containing materials, wherein the first-solvent-and-first-fraction-rich stream comprises a separated portion of the first solvent and the first fraction dissolved in the separated portion of the first solvent; separating the first-solvent-and-first-fraction-rich stream to provide the first-fraction-rich stream; contacting the first remaining portion of the bitumen-containing materials with a second solvent, wherein the first remaining portion of the bitumen-containing materials comprises the second fraction, wherein the second fraction is soluble in the second solvent, and wherein the second fraction comprises asphaltenes; separating the first remaining portion of the bitumen-containing materials to provide a second-solvent-and-second-fraction-rich stream comprising a separated portion of the second solvent and the second fraction dissolved in the separated portion of the second solvent; and separating the second-solvent-and-second-fraction-rich stream to provide the second-fraction-rich stream.
