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 25):
The method of  claim 1 , wherein the first-fraction-rich stream comprises a relatively softer bitumen having a relatively higher penetration value equal to greater than 20 tenths of a millimeter and optionally up to 600, 500 or 400 tenths of a millimeter, wherein the second-fraction-rich stream comprises a relatively harder bitumen having a relatively lower penetration value equal to 0 to 20 tenths of a millimeter, wherein the penetration values are determined at 25\u00b0 C. according to ASTM D5M-13, \u201cStandard Test Method for Penetration of Bituminous Materials\u201d by ASTM International.
