SYSTEM AND METHOD FOR EXTRACTING BITUMEN FROM TAR SAND |
摘要 |
An improved system for removing bitumen from tar sands comprises a pre-treatment system utilizing a vibratory load hopper for classifying and sizing said tar sand particles communicating with a dryer for heating and drying said tar sand particles to a predetermined temperature thereby controlling the moisture content of said tar sands. An extraction system is also included for accepting said tar sands from the dryer comprising a plurality of extraction vessels arranged in series for transporting said tar sands from a first extraction vessel to a final extraction vessel. Furthermore, a solvent system for supplying a predetermined volume of solvent flow through said extraction vessels is employed, whereby solvent is supplied to the last extraction vessel and a solvent and bitumen mixture is withdrawn from the first extraction vessel. |
