Abstract: A coke quench car emission control system includes a coke car and a filter car connected in tandem for joint movement on rails disposed adjacent a coke oven. A hood and recuperator are mounted on a third car disposed on auxiliary rails which extend longitudinally along the upper portions of both the quench car and the filter car and in end-wise alignment. The hood is adapted to be coupled to the coke oven for receiving coke during a pushing operation. The recuperation has an inlet coupled to the hood for receiving emissions and withdrawing heat therefrom. The recuperator also has an outlet which is disposed adjacent the inlet of a filter system mounted on the filter car, when the third car is positioned atop the quench car. The third car is sized so that it can be moved on the auxiliary rails from a position atop the quench car to a position atop the filter car whereby the quench car can be exposed for a quenching operation.

Abstract: A system for producing foam continuously. A body member defines a foam generating chamber. A foamable liquid is introduced into an inlet of the foam generating chamber. A gas is simultaneously introduced under pressure into the inlet of the foam generating chamber to form a mixture of foamable liquid and gas. The mixture is then flowed from the inlet of the foam generating chamber to an outlet thereof through a turbulator medium which substantially fills the foam generating chamber to thereby foam, mix and homogenize the mixture. The inlet and outlet of the foam generating chamber are in an imaginary substantially non-horizontal plane. The foamed and homogenized mixture is then removed from the outlet.

A horizontally rotatable and vertically pivotable boom has one end mounted on the gantry and a coke oven work tool on the other. The framework includes a coke quenching apparatus and conveying equipment.

Abstract: An apparatus for charging coke chambers is disclosed which effectively reduces and controls gas and dust emissions evolved during the coke charging operation. The charging apparatus includes a gas-tight enclosure which seals the immediate area surrounding the cooling chamber or serially arranged chambers in a cooling plant, a lift transport facility located internally to the enclosure for carrying a coke bucket to and from the respective coke cooling chambers, a crane or elevator for placing and removing the coke bucket from the lift transport facility, and an exhaust device for evacuating the gas and dust emissions from the enclosure. Inert gas feedlines are integrated with the charging operation to maintain an inert gas atmosphere within the enclosure.

Abstract: A coke delivery device 10 includes a swingable chute 16 for guiding coke pushed from a coke oven through a coke rack 12 into a quench car 24.The chute 16 is drivingly interconnected with a moveable fume hood 14 whereby lowering the fume hood over the quench car positions the chute 16 for coke guiding. Raising the fume hood moves the chute from the coke guiding position to a storage position concurrently spreading coke pushed into the quench car and dumping any coke remaining on the chute into the quench car.

Abstract: A coke oven charging hole that dissipates heat emanating from the oven so that the cover resists warping due to overheating. The concentration of large amounts of heat directly above the charging hole is also avoided. A lower concave housing member fits into the charging hole and is partially filled with insulation. A circular plate is fixed to this housing member so as to form an insulating air space between this plate and the insulation. One or more other plates are superimposed over this plate so as to form heat air spaces which are open to ambient air so that a laterally directed flow of air is established in these air spaces.

Abstract: A charging hole cover sealing structure in which a disc-shape cover is superimposed over the charging hole and an annulus-shaped charging hole frame. The frame has on its top surface a peripheral medial groove and an inner planar surface. The cover has a lip with a terminal downwardly projecting peripheral tongue that engages the medial groove on the frame as the lip abuts its inner planar surface so that dual gas tight seals are established. A primary continuous seal is established at the point where the lip abuts the inner planar surface on the frame. The groove is filled with a heat resistant particulate material which will cause any coke oven gases escaping through this primary seal to be condensed so as to form a particularly effective sealant material made up of a mixture of the resultant tarry condensation with the particulate material.

Abstract: An improved method and apparatus for making coke wherein the coal is heated by the walls of a multi-cell chamber means and wherein said walls are heated by electric induction in the absence of air; the raw gases from the coal are directed to a by-product plant. The coal is introduced into said chamber means and the coke is discharged from said chamber means in such a way as to provide positive displacement of both the coal and the coke to overcome the sticking and bridging properties of the coal and the coke within said chamber means. Also improved provisions are included for insuring the sealing of said chamber means while operating said chamber means under a positive pressure in order to increase the efficiency of the conversion of coal to coke without causing pollution. The coal, after being coked, is quenched to a temperature below its ignition point before being exposed to the atmosphere to prevent it from burning in order not to cause pollution nor lose yield.

Abstract: A method of recovering silicon from an aqueous slurry containing finely divided silicon particles comprising mixing at least one flocculating agent with the slurry, allowing silicon flocs to form and physically separating the silicon flocs from the slurry for re-use of the silicon contained therein.

Abstract: A coke oven battery servicing apparatus includes a coke catching and collecting bucket movable from a first position adjacent the oven to a second position clear of the oven and a coke guide cage having an opening therein which is complementary to the bucket. When in the first position the bucket collects coke spillage during oven door extraction and door jamb cleaning. When the coke guide is positioned for pushing, the bucket is moved into a third position in which the bucket is removably inserted into the aforementioned opening to become integral with the coke guide cage. The collected coke spillage is then pushed together with the coke from the oven through the guide means for disposal in a quenching receptacle or car.

Abstract: A process for producing a distillable hydrocarbonaceous stream, fuel gases and blast furnace grade coke from a heavy, high sulfur, crude oil by producing delayed coke from at least a portion of the crude oil; crushing at least a portion of the coke to provide a finely divided coke feedstock to a briquetting operation where the finely divided coke is briquetted using crude oil or topped crude oil as a binder to produce briquettes of a size from about 3/4 inch to about 3 inches with the resulting briquettes being passed to a high temperature vertical calciner where the solids are desulfurized to produce a strong blast furnace grade coke. The distillable stream and fuel gas stream are recovered from the delayed coking operation, the vertical calciner and optionally a crude oil topping operation. In some instances coke particles in the size range from about 3/4 inch to about 3 inches may be passed directly to the calciner without crushing and briquetting.

Abstract: A method and a device for feeding purging and degraphitizing air into pipes for rich gas leading to the heating walls of coke ovens. In the device a first cross-sectional opening is connected to a pipe for rich gas. This opening can be opened and closed with a first gate and is adapted to initially release only a relatively small cross-sectional aperture for passing purging air therethrough. A second cross-sectional opening is provided in the device, which is connected to the pipe for rich gas. The second opening can be opened and closed with a second gate and is adapted to release successively, with a time delay after the first cross-sectional opening, a relatively larger cross-section for passing degraphitizing air therethrough. An exchangeable screen can be placed in the aperture in the first cross-sectional opening. The degraphitizing air enters the pipe for burning off the graphite deposits resulting from the rich gas.

Abstract: To seal against the surround of the door opening of a coke oven, the door has an elongate knife-edge element which engages the surround and is held against a sealing surface on the side of the door. The knife edge element is movable past the sealing surface on the door for adjustment. The knife-edge element is divided into a plurality of mutually abutting parts in the adjustment direction. In order to allow a greater amount of adjustment of the knife edge element and to make assembly of the seal easier, holding means e.g. a plurality of brackets, are provided to hold the parts of the knife edge together in the adjustment direction and to restrain at least the outermost part from lateral movement relative to the door. The holding means permits relative sliding of the parts in the longitudinal direction.

Abstract: Industrially crystallized potassium chloride having a potassium chloride content of at least 95 weight percent and containing a minor contaminating amount of inorganic metal salt impurities, e.g., sodium chloride, is purified by leaching compacted particles of said potassium chloride with an aqueous leaching solution, the solute of which solution is selected from the group consisting of potassium chloride and mixtures of potassium chloride and sodium chloride. The leaching solution is saturated with respect to potassium chloride and substantially unsaturated with respect to sodium chloride. The compacted particles are maintained in contact with the leaching solution for a time sufficient to reduce substantially the sodium chloride content thereof, and potassium chloride particles of reduced sodium chloride content are recovered from the leaching solution. The leached compacted particles are transparent and comprise single and compound euhedral cubic crystals.

Abstract: A coke car is traversed along a battery of coke ovens and receives hot coke discharged through a fall space in an overlying smoke collector hood. The car is moved slowly only a short distance along the battery during the coke pushing operation while it is loaded wih coke at one end of the car and progresses slowly to the other end thereof. Horizontal end sealing plates are fitted to the car and the hood at the level of the top edges of the end walls on each side of the car and hood. The total of the length of the two sealing plates is not less than the distance traveled by the car during coke pushing. Gaps are left between the bottom edges of the side walls of the smoke hood or extension plates disposed thereon and the sealing plates on the coke car. The gaps allow entry of air into the hood for uniform extraction of the emissions formed during the coke pushing operation. In addition, gaps of equal width can also be left between the top edges of the longitudinal walls of the car and hood.

Abstract: Production of coke from coal is improved by mixing self-feeding coal with compacted non self-feeding coal prior to carrying out the coking process. Preferably, there is about 10% to about 60% by weight of the non self-feeding coal based on the total charge. Binders may be used and it is preferred that the non self-feeding coal be preheated to approximately 150.degree. C. to 250.degree. C. prior to mixing. In the event that an aqueous emulsion is used as the binder, the preheating step may be omitted. Coke of superior abrasion resistance is obtained by the foregoing method.
