  • Apparatus for control of coke oven emissions
    Patent number: 4360404
    Abstract: Enclosure and exhaust apparatus is provided to enhance control and removal of coke-side emissions during a push in the operation of a coke oven battery. The gaseous and entrained particulate emissions are initially confined to a first longitudinally extending containment zone where the emissions are directed, under the influence of its gaseous thermal drive, upwardly and laterally outwardly away from the coke-side face of the battery. The emissions are then transferred, at the peak of the first containment zone, laterally, through a gas expansion throat, into a second longitudinally extending containment zone that is adjacent and parallel to the first containment zone. Contemporaneously with entering the second containment zone, a portion of the emissions is removed therefrom through an exhaust conduit located at the upper reaches or peak portion of the second containment zone.

  • Apparatus for entrained coal pyrolysis
    Patent number: 4359363
    Abstract: This invention discloses a process and apparatus for pyrolyzing particulate coal by heating with a particulate solid heating media in a transport reactor. The invention tends to dampen fluctuations in the flow of heating media upstream of the pyrolysis zone, and by so doing forms a substantially continuous and substantially uniform annular column of heating media flowing downwardly along the inside diameter of the reactor. The invention is particularly useful for bituminous or agglomerative type coals.

  • Gas-collecting apparatus for coking installation
    Patent number: 4359364
    Abstract: A coking installation has a coking chamber whose coke side opens above a bench level that is above ground level. A coke-guide track at this bench level supports a coke guide which is displaceable along the track and alignable with the coke side of the chamber. A ground-level quenching-car track supports a quenching car which can be displaced along the car track to receive coke pushed from the chamber through the guide. A gas-collecting apparatus has an outer track supported on the ground outside the coke-guide quenching-car tracks. A portal support is displaceable along this outer track and has outrigger arms carrying a gas-collecting hood above the quenching car. The gas-treatment plant has a stationary conduit provided on the ground underneath the portal support and is connected via a movable conduit to the hood on the support.

  • Method for quenching coke
    Patent number: 4358343
    Abstract: Preheated bulk material capable of coking is quenched by flowing the quenching liquid through the loose bulk material, whereby the bulk material is substantially closed off relative to the atmosphere. The liquid is applied to the top of the bulk material in a quenching chamber which is closed at its top by a sealed cover and which has an open grating for a horizontal bottom. The steam formed by the quenching liquid and, if formed, any excess quenching liquid are drawn off from the quenching chamber through the open grating. The total quantity of quenching liquid to be supplied as a function of time is controlled by a valve through a control signal depending on the chemical and physical properties constituting bulk material characteristics prior to the heating of the coal. The control signal also takes into account the type of the intended heat treatment in the form of quenching characteristics.

  • Process for drying and preheating coal utilizing heat in dry cooling or quenching of coke
    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.

  • Method of solid-state pyrolysis of organic polymeric substances
    Patent number: 4353782
    Abstract: The yield of good-quality bodies consisting of vitreous carbon is increased to substantially 100% when the pyrolysis is performed in a reaction vessel in which a collecting container or a collecting disc for the condensable volatile decomposition products which is open at its upper side is arranged above the polymeric substances to be pyrolyzed. The collecting disc divides the interior of the reaction vessel into two parts, a passage for gases remaining between the upper part and the lower part. During the pyrolysis, a spatial temperature distribution is adjusted in the reaction vessel which results in a pulsating evaporation and condensation of the decomposition products, so that the decomposition products are completely removed.

  • Processing of heavy high-sulfur feedstocks
    Patent number: 4351702
    Abstract: A heavy high-sulfur hydrocarbonaceous feedstock is partially delayed coked and partially formcoked. The coke products are screened, with larger particles being calcined at desulfurizing temperatures and smaller particles being recycled to the formcoker. Overhead products from both coking operations are combined, fractionated, and desulfurized. The heaviest cut from the fractionator is combined with the feedstock as recycle.

  • Hydrocarbon heating apparatus
    Patent number: 4351803
    Abstract: Hydrocarbons are preheated, particularly for a hydrodesulfurization process by first heating the hydrocarbon stream to produce a vapor and a liquid stream, thereafter superheating at least some of the vapor phase and mixing the superheated vapor phase with the liquid phase to generate the hydrocarbon feedstream at the desired temperature. By this procedure only the evaporated hydrocarbons are subjected to a high temperature, but not the heavier hydrocarbons.

  • Method for circumferential dimension measuring and control in crystal rod pulling
    Patent number: 4350557
    Abstract: The circumference of a crystal rod is monitored and controlled during the rod growing process by providing relative rotation between the growing crystal rod and a melt of the crystal material as the rod is being pulled from the melt according to the Czochralski method, and by using a radiation-sensitive control system for adjusting growth conditions of the rod in response to variations in a radiation signal which is indicative of the circumferential dimension of the rod. An electronic circuit integrates the radiation signal over each complete rotation of the rod, thereby eliminating unnecessary adjustment of the growth conditions in response to diametric variations of the rod which recur regularly in each rotation.

  • Spray nozzle for coke oven gas-collecting system
    Patent number: 4348258
    Abstract: A spray nozzle for use in the elbow interconnecting a coke oven ascension pipe and a main, characterized in having frusto-conical nozzle orifices to generate sprays which commpletely cover the elbow cross section only when they reach the transition between the elbow and the coke oven main. The invention resides in the realization that in order to optimize the performance of the nozzle, there must be a specified relationship between the inlet diameters of the frusto-conical orifices, the outlet diameters of the orifices and the radial and circumferential distances between the centers of orifices arranged in concentric circles.

  • Apparatus for solid gas reaction
    Patent number: 4348363
    Abstract: Continuous fluorination of carbon is carried out by employing an apparatus for contact reaction of solid powder and reactive gas which comprises a horizontal reactor having a trough provided with weirs (e.g. height: 1 to 6 mm., interval: 5 to 30 cm.) and a vibrating means for vibrating the trough, and in which carbon particles supplied continuously are transported on the trough in a form of thin layer by the vibration of the trough while continuing the reaction by contacting efficiently the carbon particles with a fluorine gas. The contact reaction is efficiently conducted without accumulating the reaction heat to produce the fluorinated carbon in high yields, and the process is useful for the mass production. The apparatus is also useful for various contact reaction of a solid powder and a reactive gas.
