Abstract:
An apparatus 1 for disposal of wastes comprises a measuring hopper 2 for measuring a charging amount of a waste to be disposed such as domestic wastes, industrial wastes or the like or a charging amount of a solid fuel such as coke, coal or the like, a charging hopper 3 for charging the waste and the solid fuel respectively measured with the measuring hopper 2, a melting furnace 4 for melting the waste charged from the charging hopper 3 at a high temperature to conduct detoxification thereof, and a charging damper 5 arranged between the charging hopper 3 and the melting furnace 4 and having a multistage sluice valve system 9 capable of charging the waste and the solid fuel charged in the charging hopper 3 into the melting furnace 4 without outflowing of a furnace gas to exterior.
Abstract:
A process to transform solid, low-level, radioactive waste produced from oil and gas production into a form that may be safely disposed of, such as by re-injection into geologic formations in the Earth.
Abstract:
Disclosed is an apparatus for manufacturing alternative combustion fuel for an industrial boiler, which is capable of easily forming an ionic bond between water and oil, of directly conducting a combustion process using a burner without the need for a preheating process to a predetermined temperature before the combustion, and of decreasing the discharge of air pollutants, such as sulfur gas, nitrogen gas, carbon monoxide, carbon dioxide, and dioxin.
Abstract:
Plume is mitigated by targeting treatment chemicals to locations in a furnace, which are connected with plume opacity. The effectiveness of targeted in furnace injection, in fuel introduction and in furnace introduction of slag and/or corrosion and/or plume control chemicals are determined, as are the effectiveness of targeted in furnace injection, in fuel introduction and in furnace introduction of combustion catalysts. Then, the effectiveness of various combinations of the above treatments are determined, and a treatment regimen employing one or more of the above treatments is selected. Preferred treatment regimens will contain at least two and preferably three of the treatments. Chemical utilization and boiler maintenance can improved as LOI carbon, slagging and/or corrosion are also controlled.
Abstract:
A method of using high temperature plasma to disintegrate waste containing titanyl phthalocyanine (TiOPc) comprises heating a mixture of titanyl phthalocyanine (TiOPc), a vitrifying material and optionally selected waste soil to a temperature of 1,220° C. to 10,000° C. until the mixture becomes a molten lava. The plasma breaks down the titanyl phthalocyanine and encapsulates the benign products in the lava that is chemically very stable. Since the titanyl phthalocyanine (TiOPc) is disintegrated completely in the process, the titanyl phtbalocyanine (TiOPc) no longer represents a threat to the environmental.
Abstract:
In a method for reducing the content of polychlorinated dibenzodioxins and -furans in the exhaust gas of chemical high temperature processes handling process materials, amides or organic oxides are made available to the process under the conditions under which the polychlorinated dibenzodioxins and -furans are generated, which amides comprise of at least one of the group consisting of amidosulfonic acid, hydroxyl amino sulfonic acid and sulfamid in an amount of 0.5 to 10% of the process material.

Abstract:
A waste processing system is provided herein which entails the use of at least one fixed-position plasma arc generator for primary processing and at least one moveable plasma arc generator for secondary processing assistance and/or final conditioning 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:
A process is provided for NOx, removal at coal burning power plants, which includes introducing ammonia that is liberated upon drying a mixture of organic waste, coal combustion by-products, and optionally lime, having a pH of at least 9.5, to a coal burner in the power plant. A process is also provided for fueling a coal burner of a power plant with coal and a dried mixture of organic waste and coal combustion by-products. The present invention is further directed to the dried mixture of organic waste and coal combustion by-products made by the processes of the present invention, which may optionally be used as a soil additive or as a supplemental fuel.
