    摘要: A dry sealing leg apparatus is comprised of four chambers through which a moving bed of retorted shale particulates from an oil shale retort is passed serially: a surge chamber, a gas injection chamber, a seal leg chamber, and a gas disengaging chamber. In the gas injection chamber, a sealing gas penetrates the moving bed of shale and divides into two portions. One portion travels countercurrently to the shale through the surge chamber and enters the retort at a positive pressure to seal product gases therein. A second portion travels co-currently with the shale through the seal leg chamber and gas disengaging chamber and exits at a pressure less than that of the retort, having been reduced in pressure by resistance to its passage through the shale.A method is provided wherein shale particulates are retorted, then passed through the dry sealing leg to reduce pressure, and crushed at a lower pressure than the operating pressure of the retort, following which the crushed retorted particulates are transported by an entraining gas stream to a fluidized combustor in which a substantial proportion of combustible materials on the shale particulates is burned to release heat energy for recovery from the flue gases.

    摘要: Retorted shale particles are recovered from a retort and delivered to a gas lift for transport to a fluidized combustor by passage, serially, through a sealing vessel, a crusher preferably operating at retort pressure, and a surge vessel. In the sealing vessel, a sealing gas is introduced, and after commingling with the shale, the gas passes counter-currently to the shale and enters the retort, thus sealing the retort gases in the retort while separating the retorted shale from the retort gases. Retorted shale from the sealing vessel is transported to a crusher, wherein the shale is reduced in size to that suitable for combustion under fluidized conditions. To prevent the crushed shale from packing, the shale is passed to a surge vessel, wherein the crushed shale is held as a fluidized bed, from which the crushed shale is continuously withdrawn at a regulated rate and introduced into the gas lift leading to the fluidized combustor.

    摘要: Crushed, retorted shale particles recovered from a shale oil retort but still containing combustible materials are burned under oxidizing conditions in a fluidized combustor to remove substantially all of the hydrocarbonaceous materials. Hot combustion flue gases are recovered, divided, and delivered to two heat exchangers, the first for indirectly preheating recycled retort education gases and the second for indirectly heating water. Also recovered from the combustor are shale particles, which are introduced into a fluidized cooling vessel and therein cooled by indirectly exchanging heat with water while traces of residual hydrocarbons burn from the shale.

    摘要: A method is provided for retorting oil shale whereby full utilization of the heat energy available in the retorted shale and maximum desulfurization of the flue gas released to the atmosphere are simultaneously effected. Basically, the process comprises passing a crushed shale feed upwardly through preheating and retorting zones in a retort vessel wherein eduction of shale oil and product gases is achieved by direct heat exchange with a preheated, recycled portion of said product gases passed countercurrently to the shale feed, and then passing the retorted shale downwardly through combustion and cooling zones. Complete combustion of coke on the retorted shale in the combustion zone not only results in full utilization of the potential heat energy stored within the retorted shale but also in the production of gaseous sulfur components (mostly SO.sub.2) that chemically react with the alkaline components of the shale. Concurrent flow of gas and retorted shale in the combustion zone at temperatures between 900.degree. and 1670.degree. F permits the reaction between said SO.sub.2 and the alkaline components of the shale to proceed essentially to completion, thus desulfurizing the flue gas produced in said combustion zone.

    摘要: An apparatus for removing solids from a solids upflow vessel, preferably an upflow retort, which includes a horizontally reciprocatable carriage containing a vertical feed cylinder that extends downward from a horizontal seal plate. A vertically reciprocatable piston is located inside the feed cylinder. One section of the seal plate contains a hole and a sliding door for opening and closing the hole. During normal operations when the apparatus is used to feed solids from a feed chute to an upflow vessel, the carriage is reciprocated between a first stationary position wherein the feed cylinder is aligned with the outlet of the solids feed chute while at least a portion of the closed hole in the seal plate is aligned with and below the inlet to the upflow vessel, and a second stationary position wherein the feed cylinder is aligned with the inlet to the upflow vessel while another section of the seal plate is aligned with the outlet from the feed chute. A tram-like suspension system moveably supports the carriage from elevated structural rails. When it is desired to remove solids from the upflow vessel during a maintenance shutdown, the hole in the seal plate is opened and the carriage is moved between its first and second stationary positions such that at least a portion of the open hole is aligned with and below the inlet to the upflow vessel.

    摘要: Hot particles removed from a retort, preferably retort-sized particles of oil shale removed from a retort operating at superatmospheric pressure, are crushed and fed to a fluidized surge zone maintained under non-oxidizing conditions at substantially the pressure of the retort to forestall escape of retort gases. Raw fines are introduced into the surge zone and retorted without agglomeration by heat transferred from the hot retorted particles and/or a heated fluidizing gas stream to educe hydrocarbonaceous vapors. Educed vapors are scrubbed, condensed and separated into liquid and gaseous product streams, a portion of the latter being recycled to provide fluidizing process gas streams.

    摘要: Crushed oil shale is subjected to eduction in a solids-upflow or -downflow retort in contact with a preheated counter-currently flowing eduction gas comprising a recycled portion of the retort make gases. The problem of shale particle agglomeration is avoided by correlating the eduction gas flow rate and temperature so as to insure that the 750.degree.-850.degree. F shale temperature interval in the retort is maintained at a level sufficiently high in the retort that the total shale, or "rock" pressure bearing down on said interval is insufficient to bring about agglomeration. It is found that the problem of agglomeration is critical to the 750.degree.-850.degree. F temperature range, and that there is a definite correlation between the oil assay of the raw shale and the permissible rock pressure which the shale particles in this temperature range can withstand without undergoing agglomeration. Provision is made for shifting the 750.degree.-850.degree. F zone upwardly or downwardly in the retort.

    摘要: Hot, coarse, particles removed from a retort, preferably coarse particles of oil shale removed from a retort operating at superatmospheric pressure, are crushed to a size suitable for fluidization and then fed to a fluidization zone maintained under non-oxidizing conditions at substantially the pressure of the retort to forestall escape of retort gases. Raw fines are introduced into the fluidization zone and retorted without agglomeration using heat transferred from the hot retorted particles. Also introduced into the fluidization zone is a heated fluidizing gas stream comprised of recycle retort gas, which is employed to educe hydrocarbonaceous vapors from the fines and, optionally transfer heat. Educed vapors from the fluidization zone are recycled to the retort to be partially condensed and recovered as liquid and gaseous product streams along with other vapors educed in the retort.
