    摘要: A process for extracting crude oil from a solid, oil bearing diatomaceous earth. In the process includes the step (a) of mixing crude oil-bearing diatomaceous earthwith a heated solvent such as toluene to reduce the size of the oil-bearing diatomaceous earthand release crude oil into the solvent, step (b) of adding water to the size reduced solid and solvent mixture of step (a) to yield a mixture of crude oil+solvent+water+sized reduced diatomaceous earth, step (c) of passing the mixture of crude oil+solvent+water+sized reduced diatomaceous earthfrom step (b) through a cyclone separator to remove residual solids and to yield crude oil+solvent; and step (d) of passing the crude oil+solvent mixture of step (c) through a solvent stripper to remove solvent from the crude oil and to yield substantially diatomaceous earthand solvent free crude oil.

    摘要: Processes and systems for the above ground extraction of crude oil from a mud-water slurry well bore mined from oil rich diatomite formations. The slurry is separated into liquid and solid factions, the liquid faction having oil, water and small sized solids, and the solid faction having larger chunks of solids. The solids faction is processed to form a slurry mixture which is cooked to disassociate oil therefrom and is centrifuged to yield an oil/solvent faction, a water faction, and a lowered oil content solids faction. The oil/solvent faction is further processed to separate the oil and solvent. Alternately, the mud-water slurry is treated to form an emulsion having a neutral pH, with solids being removed and the remaining emulsion processed to break the emulsion by removal of water as a vapor to recovery crude oil, with remaining crude oil in the solids being further processed.
