    Abstract: A system for separating bitumen from shingle powder includes: a blender; a solvent tank in fluid communication with the blender; a water tank in fluid communication with the blender; a decanting tank in fluid communication with the blender; a distillation tank in fluid communication with the decanting tank; and a plurality of pumps for pumping fluids between various components of the system or out of the system. When the system is in use, the blender receives and mixes solvent from the solvent tank with shingle powder containing bitumen to produce a bitumen-infused solvent. Water is supplied to the blender from the water tank to wash an interior of the blender. Bitumen-infused solvent received in the decanting tank from the blender is separated from excess water. Bitumen within the bitumen-infused solvent is isolated within the distillation tank.
