Calderon, A

An improved method and apparatus for recovering shale oil from shale wherein the shale is mined, crushed and pyrolized electrically in surface facilities by induction in a chamber made up of a plurality of cells in the absence of air and the raw gases are directed to a condensing means for separating the liquids from the gases. The invention also describes a method and apparatus for making use of the residue from the liquids separated from the gas in order to use said residue economically and generate electric power for the induction system used in the instant invention. The invention further discloses means for the recovering of the heat energy contained in the spent shale. The invention also discloses a method and apparatus for the disposal of the spent shale in an environmentally acceptable manner in order to prevent pollution and save the great quantities of water needed for reclamation.
