METHODS FOR PROCESSING AN OIL SAND SLURRY OR A BITUMEN EXTRACT STREAM

摘要

A method may include providing a bitumen extract stream, having bitumen dissolved in a first solvent, and suspended fines; separating the bitumen extract stream into a concentrated fines stream and a low fines bitumen extract stream; producing agglomerated fines by agglomerating the concentrated fines stream; forming washed agglomerated fines by washing the agglomerated fines with a washing solvent that removes residual bitumen extract from the agglomerated fines; producing dry solids by removing the washed solvent from the washed agglomerated fines; and producing a bitumen product stream by removing the first solvent from the low fines bitumen extract stream.
