    Abstract: An apparatus and process are provided for depressurizing, cooling, and, optionally, moisturizing retorted oil shale produced in an oil shale retort operated at superatmospheric pressure. Hot retorted oil shale particles are gravitated from the retort and into an elongated, multichambered vessel. In the upper chambers of the vessel the particles are partially cooled by contact with a controlled flow of liquid water. The water, having been totally vaporized, is removed from the particles at a rate which prevents the substantial flow of gases between the vessel and the retort. In the lower chambers of the vessel, the particles are first stripped of entrained hydrocarbon gas by gravitating through a countercurrently flowing stream of stripping gas and then brought to ambient pressure by gravitating through a long, narrow seal leg. Optionally, the depressurized and partially cooled particles are then further cooled and moisturized by admixing with a controlled flow of liquid water.

  • Patent number: 4407699
    Abstract: A process and apparatus for the dry cooling of coke involves the provision of a vessel having therein first and second zones in full communication with each other. Hot coke from a coking operation is introduced into the first zone and is passed through the first and second zones. Raw coke oven gas from the coking operation is introduced into the first zone, thereby reducing the temperature of the coke, while cleaning the raw coke oven gas to form cleaned coke oven gas. The cleaned coke oven gas is removed from the first zone, cooled, and then directly or indirectly utilized as a heat carrier gas introduced into the second zone to therein further reduce the temperature of the coke. The thereby further cooled coke is removed from the second zone.

  • Patent number: 4406747
    Abstract: The present specification describes and claims a method and apparatus for use in cooling the solid residue of gasification of a reactor operated at a pressure above atmospheric for the gasification of carbonaceous materials. The residue of gasification is conducted out of the reactor into a cooling apparatus located therebelow and flows through the cooling apparatus from the top to the bottom thereof. A cooling liquid is introduced into the solid residue in the upper region of the cooling apparatus and is metered such that the greater portion of the heat contained in the residue is eliminated in the form of heat of vaporization, sensible heat and chemical binding energy with the resultant steam and reaction products produced. The remaining residual heat which corresponds to the difference between the desired final temperature and the temperature after cooling by the liquid, is eliminated by a gas blown into the bottom region of the cooling apparatus and/or by indirect heat exchange.

  • Patent number: 4371425
    Abstract: Coke is dry cooled in a shaft-like cooler by gases conveyed through the coke. The cooler comprises a top antechamber below a charging opening, a cooling chamber under the antechamber and having a gas inlet and a coke outlet at the bottom end. Between the antechamber and the cooling chamber, there is a cylindrical wall having a gas inlet. The cooling chamber is divided by radial walls which abut a central masonry core and divide the chamber into three shaft-like chambers to insure uniform descending of the coke. A prop is placed at the center of each component shaft for deflecting the descending coke from a central region. Cooling gas is supplied through a pipe having a downwardly-directed opening below a central masonry core. Additional cooling gas is supplied by an annular chamber surrounding a cone at a coke outlet of the cooling chamber.

  • Patent number: 4354903
    Abstract: A three-cycle process as disclosed for drying and preheating coking coal using the heat from cooled coke. Cooling gas is passed over hot coke to heat the cooling gas and cool the coke. The heated cooling gas is then passed through a waste heat boiler and then back to the hot coke in a coke cooling chamber. This completes the first closed cycle. Water is supplied to the waste heat boiler to form steam. The steam is supplied to a fluidized bed of wet coal to indirectly preheat and dry the wet coal in a second cycle. The wet coal is fluidized using fluidizing gas which converts water in the wet coal into steam. Some of the steam is condensed from the combination of fluidizing gas plus steam and then the fluidizing gas is returned to the bed. Steam from the waste heat boiler is also supplied to the fluidizing gas before it re-enters the bed to heat the fluidizing gas.

  • Patent number: 4342622
    Abstract: In a formed coke process of the type in which carbonization and calcination of coal is carried out prior to briquetting, the hot calcined char is cooled by means of a hydrogen-rich gas at superatmospheric pressure so as to effect concurrent cooling and desulfurization of the char. High sulfur coal containing 1.5 to 4 wt. % sulfur can be used while obtaining a char and a formed coke product with a sulfur content of 0.8 wt. % or less. The cooling can be done in two stages: (1) a first stage in which sulfur removal and cooling to a temperature not lower than about 800.degree. F. are accomplished with a hydrogen-rich gas, and (2) a second stage in which further cooling to about 200.degree. F. or less is accomplished with an inert gas.
