Abstract:
A waste processing system is provided herein which entails the use of at least one fixed-position plasma arc generator (36) for primary processing and at least one moveable plasma arc generator (38) for secondary processing assistance and/or final condition of the slag prior to exit from the reactor vessel. This optimum processing environment is provided by control of reactor vessel configuration and real time control of processing characteristics to ensure maximum processing efficiency.
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 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:
In a method for processing used cathode material containing carbon, in particular used cathode troughs from aluminum production, the cathode material is put into a shaft furnace and, in order to gasify carbon, is subjected to a thermal treatment in the shaft furnace at a temperature above the ignition temperature of the carbon and above the evaporation temperature of toxic substances contained in the used cathode material. The reaction gases are conducted co-current with the carbon in a first longitudinal section of the shaft furnace and countercurrent to the carbon in a second longitudinal section of the shaft furnace. The reaction gases are drawn from a region of the shaft furnace having an enlarged cross-section between the longitudinal sections and are preferably subjected to an after-treatment.
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.
