  • Pulsed retorting with continuous shale oil upgrading
    Patent number: 4532991
    Abstract: One or more in situ oil shale retorts are alternately operated in a combustion mode and a purge mode with a steam or water purge to produce a greater yield of shale oil. Hydrogen-rich off gases emitted during purging are mixed with the shale oil in a reactor in the presence of a catalyst, after being stripped of carbon dioxide, to produce a high quality shale oil. The reactor off gases, purge mode off gases, and/or hydrogen gases can also be used as the purge gas.

  • Disposal of spent oil shale and other materials
    Patent number: 4529497
    Abstract: A process is provided for retorting synthetic fuels, such as oil shale, and disposing of the tailings in an environmentally acceptable manner. In the process, raw synthetic fuels are retorted in a surface retort to produce synthetic oil. The synthetic oil is dedusted and upgraded. The retorted synthetic fuels can be combusted and moisturized to generate heat for the retort, produce steam, and facilitate handling of the residual waste material (tailings). A disposal site of spent synthetic fuels, spent upgrading catalyst, dust, and/or other material is formed with vapor breaks at one or more levels in the pile. Air is passed through the vapor breaks to evaporate leachate rather than permitting the leachate to carry pollutants from the pile into the ground and surrounding bodies of water.

  • Separation of hydrogen sulfide from gaseous and non-aqueous liquid streams
    Patent number: 4526774
    Abstract: An indirect hydrogen sulfide conversion process for the production of elemental hydrogen and sulfur. The process is based upon the electrochemical oxidation of iodide in an aqueous solution with a pH in the range of 0 to 1 at high current densities and current efficiencies. Hydrogen gas is produced concurrently with soluble triiodide. Treatment of a gaseous or non-aqueous liquid stream with electrolyte solutions containing triiodide yields a sulfur product in plastic form. The sulfur product can be recrystallized from a solvent to yield sulfur of comparable purity to that presently produced.

  • Cooling and condensing of sulfur and water from Claus process gas
    Patent number: 4526590
    Abstract: The Claus process gas is cooled in a condenser to condense most of the sulfur vapor in solid form. The gas leaving the condenser is then further cooled to condense water without producing substantially any sulfur in an undesirable form. The resulting gas of reduced water content is useful in Claus reaction, particularly the low temperature Claus reaction in which the product sulfur is adsorbed on the catalyst.
