Abstract: A coke oven door includes a mainframe, a diaphragm assembly coupled with the mainframe, and a plurality of load-exerting assemblies attached to the mainframe. The diaphragm assembly includes a pan and a sealing edge structure attached to the pan. The sealing edge structure includes a load-receiving surface, a door-sealing surface spaced from the load-receiving surface, and a plurality of scallops spaced from one another. Each of the load-exerting assemblies is positioned and configured to selectively, operably apply a load to the load-receiving surface of the sealing edge structure. The scallops are configured and positioned to facilitate deflection of the sealing edge structure, in response to loads applied to the load-receiving surface, such that the door-sealing surface is configured to be positioned in contacting, and at least substantially sealing, engagement with a door jamb of a coke oven body.

Abstract: Water from underground and other sources is brackish and not suitable for human consumption. Naturally present dissolved chemicals in water make it brackish. The precipitants and dissolved chemicals need to be separated from water to make it consumable. A combination of aeration systems, filtration systems, crystallizers and hydrophobic membrane carrying filter are used to desalinate the brackish water. Pressure retarded osmosis process using an apparatus is also used to further purify water. Various heat exchange apparatus are used for energy conservation and efficient processing of water in a feasible way. The disclosure enables to purify water and provide a useful technology to eradicate water scarcity.

Abstract: A method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A mined hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom. Hydrocarbon products can be collected from intermediate locations within the permeable body. Advantageously, an intermediate fluid collection system can be used to draw a hydrocarbon product from the permeable body at preselected locations. Such intermediate collection can provide hydrocarbon product fractions which can reduce or eliminate the need for full-scale distillation of a hydrocarbon product having a full range of products such as that typically found in crude oil.

Abstract: A low-energy input process for the pyrolytic conversion of biomass to charcoal or carbonized charcoal is provided. The biomass is sealed in a container, pressurized, then air is introduced at the proximal end of the container and released at the distal end of the container. The biomass is ignited by a heater at the distal end. The operation of the heater is halted after initial ignition and the biomass is allowed to continue to burn in a proximal-to-distal end airflow to finish the conversion.

Abstract: To make it easier to carbonize the processing target material to a desired carbonized condition and also to make installment within a limited installment space possible. A carbonizing apparatus includes a carbonizing furnace having a feeding portion for a processing target material, a takeout portion for a carbonized material, a blowout portion for combustion air and an exhausting portion for combustion exhaust gas and a stirring device capable of stirring the processing target material inside the carbonizing furnace. The blowout amount of the combustion air is adjustable. The apparatus is operable to carbonize the processing target material fed from the feeding portion, with stirring, spontaneously combusting and moving the material while moving this material toward the takeout portion and subsequently to take out the resultant carbonized material from the takeout portion.

Abstract: A pyrolysis process and reactor converts various hydrocarbons such as waste materials, for example, scrap polymers, tires, etc., into various chemical components or amounts thereof, not otherwise produced by conventional pyrolytic processes. A large reactor size is utilized in association with a low heat input per unit weight of charge. A thick pyrolyzate/“char” layer is formed during pyrolysis. The product or various components thereof can be utilized as a fuel or octane additive.

Abstract: An improved process and apparatus for the destructive distillation or pyrolysis of rubber, such as used rubber tires, to produce liquid and gaseous hydrocarbons and a solid carbonaceous char. A heat transfer gas circulating in a circulation loop is used to cool the hot char produced in the distillation chamber of a distillation oven, the circulation loop having some means for removing the heat transferred to the heat transfer gas from the hot char. In one embodiment, two distillation ovens are operated in off-set, batchwise distillation cycles. The distillation cycles in the two ovens are coordinated so that a fresh charge of rubber feed is introduced into the distillation chamber of one of the ovens as the distillation of rubber in the other oven is concluded.

Abstract: Whole tires are heated in a pressure vessel to a range of between 700.degree. Farenheit and 900.degree. Farenheit, with pressure within the vessel achieved and maintained at 100-300 pounds per square inch. The vessel has a heat tube which extends through the center of the tires contained therein to uniformly apply heat. The method produces a low sulfur oil and gas, and a useable coke product from the pryolysis of the tires.

Abstract: A method and apparatus for producing fuel and carbon black from rubber are disclosed. The method and apparatus produce a liquid fuel that is low in sulfur content, gaseous hydrocarbons, and solid carbonaceous materials from used rubber tires. Rubber is heated under negative pressures in the presence of a minimal amount of oxygen. The methods and apparatus of the present invention also produce little air emissions and conserve energy.
