Abstract:
A method of treating recyclable raw materials containing valuable metals is provided, the method including the steps of feeding recyclable raw materials (W) containing valuable metals into a rotary kiln furnace (2) in which a refractory product having an Al2O3—Cr2O3 content of 70% or greater is used for an inner wall; feeding an additive (A) containing SiO2 as a major component into the rotary kiln furnace (2) so as to increase a viscosity of a slag (S) flowing along the inner wall, thereby the recyclable raw materials (W) are attached on the slag (S) having a high viscosity such that at least part of the recyclable raw materials (W) is exposed to the inside of the rotary kiln furnace; and burning/melting the recyclable raw materials (W) attached on the slag (S) in the rotary kiln furnace (2).
Abstract:
Disclosed are novel engineered fuel feed stocks, feed stocks produced by the described processes, methods of making the fuel feed stocks, methods of producing energy from the fuel feed stocks. Components derived from processed MSW waste streams can be used to make such feed stocks which are substantially free of glass, metals, grit and noncombustibles and contain a sorbent. These feed stocks are useful for a variety of purposes including as gasification and combustion fuels. In addition, one or more sorbents can be added to the feed stocks in order to reduce the amount of a variety of pollutants present in traditional fuel and feed stocks, including, but not limited, sulfur and chlorine. Further, these feed stocks with added sorbent can mitigate corrosion, improve fuel conversion, extend power generating plant lifetime, reduce ash slagging, and reduced operating temperature.
Abstract:
A vehicle configured to carry solid refinery waste is disclosed. The vehicle includes a mobile tank including a plurality of compartments and at least one buffer disposed between each of the plurality of compartments. The vehicle further includes a plurality of manhole openings on a top wall of the tank, each manhole opening being associated with one of the plurality of compartments and being sized to enable an agitator to pass therethrough. The vehicle also includes a plurality of connectors, each connector being affixed to the mobile tank for movement therewith to selectively secure the agitator and a plurality of fluid valves sized to permit an emulsion of the solid refinery waste and at least one diluent to pass therethrough in flowable form.
Abstract:
An apparatus for mixing tank contents including sedimentary material is disclosed. The apparatus includes an agitator connected to a support including a plurality of detachable sections. The apparatus further includes a frame adjacent an opening in a top of the tank. The apparatus also includes an actuatable connector for interconnecting the frame to the support. The connector is configured to be actuated in order to lift a first portion of the support above the frame while a second portion of the support below the frame is maintained, to thereby cause a gap between the first portion and the second portion enabling at least one of the detachable sections to be inserted into the gap. The apparatus also includes at least one actuator for causing the connector to lift the first portion in order to cause the gap, and for lowering the first portion and the second portion.
Abstract:
A method for disposing of solid refinery waste is disclosed. The method includes removing solid waste constituents from inside a refinery tank using excavating machinery, delumping the solid waste constituents, and conveying the delumped solid waste constituents into a mobile tank. The method further includes transporting the delumped solid waste constituents in the mobile tank to a burning facility, adding at least one diluent, mixing, and pumping from the mobile tank a flowable mixture of refinery waste and the at least one diluent at the burning facility.

Abstract:
A waste-to-energy conversion apparatus comprising a primary combustion chamber capable of holding a load of waste, and the primary combustion chamber further comprises a heat source to heat the waste and generate a syn gas stream, grates, within the primary chamber, capable of supporting the load of waste during heating, a mixing chamber wherein the syn gas is mixed with additional combustion gas, a multi-chambered secondary combustion chamber for combusting the mixture of syn gas and additional combustion gas, and an energy extraction system for extracting the heat energy generated by the combustion of the mixture of syn gas and additional combustion gas.
Abstract:
A Carbon Conversion System having four functional units, each unit comprising one or more zones, wherein the units are integrated to optimize the overall conversion of carbonaceous feedstock into syngas and slag. The processes that occur within each zone of the system can be optimized, for example, by the configuration of each of the units and by managing the conditions that occur within each zone using an integrated control system.
Abstract:
Techniques are generally described for producing cement clinker that includes forming cement clinker in a kiln, heating waste additives, and applying the heated waste additives to the cement clinker in the kiln. Additionally, examples are generally described that include an apparatus for producing cement clinker that includes a kiln in which cement clinker is formed and a device having an opening positioned inside the kiln which provides heated waste additives to the kiln for application to the cement clinker. An example device for applying waste additives to cement clinker includes an eductor configured to receive waste additives and transport air in which the waste additives are pneumatically entrained, and includes a lance coupled to the eductor and configured to receive the pneumatically entrained waste additives and receive a support gas that reacts with the waste additives and heats the same for application to the cement clinker.
