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.
