  • Patent number: 4589700
    Abstract: The present invention relates to a combination of open cast strip mining and auger mining of thin seams of hydrocarbonaceous deposits. In this mining method, a first working pit is stripped to expose the deposit, the hydrocarbonaceous material extracted and the exposed deposit seam face of at least one highwall is auger mined. A second and successive working pits are opened parallel to but spaced apart from the preceding working pit by a predetermined distance thereby leaving an undisturbed overburden portion therebetween. In the second and successive working pits, the overburden is stripped and disposed in the void of its preceding pit, the hydrocarbonaceous material extracted and the hydrocarbonaceous material beneath the undisturbed overburden portion between adjacent working pits substantially removed by auger mining from one or both working pits. The stripping is accomplished by the use of a dragline and the width of the undisturbed overburden portion is related to the working radius of the dragline.

  • Patent number: 4585063
    Abstract: An oil shale process is provided to retort oil shale and purify oil shale retort water. In the process, raw oil shale is retorted in an in situ underground retort or in an above ground retort to liberate shale oil, light hydrocarbon gases and oil shale retort water. The retort water is separated from the shale oil and gases in a sump or in a fractionator or quench tower followed by an API oil/water separator. After the retort water is separated from the shale oil, the retort water is steam stripped, carbon adsorbed and biologically treated, preferably by granular carbon adsorbers followed by activated sludge treatment or by activated sludge containing powdered activated carbon. The retort water can be granularly filtered before being steam stripped. The purified retort water can be used in various other oil shale processes, such as dedusting, scrubbing, spent shale moisturing, backfilling, in situ feed gas injection and pulsed combustion.

  • Patent number: 4584088
    Abstract: A method for producing a kerogen concentrate from oil shale comprises treating shale with a first aqueous caustic treating solution to produce a shale product of substantially transformed mineral content, and then treating the shale product with an aqueous acid solution to produce a first kerogen concentrate. The acid solution extracts minerals from the shale product to make a low ash content first kerogen concentrate. A spent acid solution containing the extracted minerals can be treated to recover minerals therefrom. The first kerogen concentrate is then treated with a second aqueous caustic treating solution to produce a second kerogen concentrate of lower ash content. The first and second aqueous caustic treating solutions are preferably the same.

  • Patent number: 4581867
    Abstract: Specially configured refractory anchors are provided to minimize erosion and increase the useful life of refractory linings in reactors and other vessels. The refractory anchors have a frustroconical base and an overhead crossbar with an intermediate portion and opposite ends. At least one of the opposite ends has an arcuate portion to provide a curved baffle to arcuately deflect and block gases flowing along the refractory lining adjacent to the refractory anchors. Desirably, the crossbar provides an erosion resistant barrier to help protect the structural integrity of the refractory linings. The base extends downwardly from the crossbar and reinforces the refractory lining. The flared sides of the base diverge towards the opposite ends of the crossbar at obtuse angles of inclination to provide pockets for receiving and holding the refractory lining. In one embodient, the refractory anchor has an S-shaped crossbar with reverse bent opposite ends.
