20100051511Method For Releasing Organics From Shale And Like Materials To Produce A Liquid Shale Fuel - Method for release of organic materials from shale oil and like solid substances, by treating shale oil powder in a liquid medium, with vortical movements, wave movements, acoustic turbulent streams, or combinations thereof. The treatment causes foaming of the liquid medium followed by separation of the foam from the liquid medium, whereby the foam is enriched with organic materials released from the shale oil powder. The foam can be placed in a liquid organic solvent and treated with vortical movements, wave movements, acoustic turbulent streams, or combinations thereof. The treatment causes the extraction of hydrocarbons into the solvent, and the inorganic shale material to precipitate. The remaining inorganic sold material can be utilized in the manufacture of construction materials. The obtained solution of the extracted hydrocarbons into the solvent represents a synthetic fuel, which could be used after slight reforming as motor fuel, jet fuel, or the like.03-04-2010
20130075306MULTI-STAGE COUNTER-CURRENT FROTH SETTLER AND METHOD OF USE - A method for recovery of bitumen from a bitumen-containing froth utilizes solvent and a single, froth settling vessel having a plurality of internals therein. The froth is first diluted with enough solvent to reduce the viscosity of the froth and the diluted froth is added to the vessel above the internals. Additional of the solvent is added to the vessel, either below the internals, intermediate the internals or both and is flowed counter-current to the diluted froth which is flowing downwardly over the plurality of internals. A gradient of solvent concentration relative to hydrocarbon concentration is formed through the internals which act as multiple stages of separation. The product, being bitumen and other light components, are carried with the solvent to the top of the vessel. The heavier components such as water, solids and asphaltene aggregates fall to the bottom of the vessel by gravity. Where paraffinic solvents are used, the solvent to bitumen ratio for the initial dilution of the froth is kept below a ratio at which the asphaltenes are rejected. Substantially all of the asphaltene rejection occurs in the settling vessel as the solvent to bitumen ratio increases therein.03-28-2013
