Abstract
A system and methods for power generation uses non-aqueous solvent. The method includes treating oil sands with a non-aqueous solvent to extract bitumen in an extraction process and separating the non-aqueous solvent from the bitumen in a solvent recovery process. The method also includes heating the non-aqueous solvent, expanding the non-aqueous solvent to generate power, and cooling the non-aqueous solvent. The method further includes recycling at least a portion of the non-aqueous solvent to the extraction process.
