摘要： Inexpensive, highly effective methods for the in-situ reduction of hexavalent chromium to the non-toxic trivalent oxidation state in soil and groundwater containing hexavalent chromium are provided, which may reduce hexavalent chromium concentration in soil to as low as 5 mg/L. The methods involve sampling soil comprising hexavalent chromium to determine a reaction amount of a reducing agent, providing a frame on a top surface of the soil, wetting the soil, spreading a reducing agent on the top surface of the soil, and flushing the soil with water to dissolve the reducing agent. The reducing agent may be a chemical agent, a biological agent, or a combination of chemical and biological agents. The biological reducing agents may include sludge from wastewater, return activated sludge, waste activated sludge, leachate from landfill or from composting operations, or compost material from municipal wastewater, industrial wastewater, or solid waste operations.

摘要： This relates to a furnace that is useful in safely detonating or demilitarizing munitions or explosives, particularly small caliber munitions. The preferred variation includes a series of chambers having a set of runners or tracks passing amongst the various chambers to allow movement of the munitions from chamber to chamber in trays. The first chamber is heated in such a way so that a tray of munitions placed on the runners in this chamber are baked and detonated. After the detonation is generally complete, the tray containing the then-detonated munition fragments is slid through an opening at the end of that heated detonation chamber into a first cooling chamber. Generally, this movement takes place by addition of another tray containing non-detonated munitions into the first chamber. The furnace may also contain a second cooling chamber to assure both that the subject munitions are detonated and to allow then-safe exiting of the completely detonated munitions from the second cooling chamber onto an external extension of the track. The furnace is configured so that the munitions, whether detonated or not, remain in trays which may be slid through an operating unit without substantial hazard. Also included is a scrubber for removing noxious or deleterious components of gases produced by the detonation before it is passed into the atmosphere. Finally, this includes a method of using a chambered furnace to detonate small arms munitions or other explosives.
摘要翻译：这涉及一种可用于安全地爆炸或非军事化弹药或爆炸物，特别是小口径弹药的炉。优选的变型包括一系列腔室，其具有穿过各个腔室之间的一组跑道或轨道，以允许弹药从腔室中移动到托盘中。第一个室以这样的方式加热，使得放置在该室中的流道上的弹药盘被烘烤和引爆。在爆炸一般完成之后，包含那个引爆的弹药碎片的托盘在该加热的爆炸室的末端通过开口滑入第一个冷却室。通常，这种运动通过在第一室中添加另外一个含有非引爆弹药的托盘来进行。炉子还可以包含第二冷却室，以确保主体弹药被引爆，并允许将完全引爆的弹药从第二冷却室安全地排出到轨道的外部延伸部上。炉子被配置成使得弹药（无论是否被引爆）都保留在可能通过操作单元滑动的托盘中而没有实质的危险。还包括一个洗涤器，用于消除爆炸产生的气体在进入大气之前产生的有害或有害成分。最后，这包括使用室式炉引爆小武器弹药或其他爆炸物的方法。

摘要： The present invention relates to a plasma process and appropriate equipment well adapted for eliminating toxic or hazardous organic compounds, such as petroleum, oils, pesticides, herbicides and various hydrocarbons, orginitated from petrochemical spills or inappropriate discard/handling, from different materials, such assail, sludges; the process and appropriate equipment can also be used to remove the hydrocarbons contained in the sludge formed at the bottom of petroleum storage tanks. The plasma process, with the appropriate equipment, object of the invention, has the following advantages as compared to the other processes used to treat similar materials: removal of the contaminants to less than 0.1% in weight of the soil or sludge; continuous operation; possibility of recovering the contaminants when desired; high energy efficiency of the process; and insignificant amount of gases to be treated. The plasma process utilizes a plasma system for providing enough energy to the contaminated soil or sludge for the hydrocarbons to volatilize, keeping the temperature of the process between 400 and 900null C. The volatilized compounds after leaving the plasma reactor are collected in condensers, where the hydrocarbons can be recovered, in the form of a liquid hydrocarbon (oil). The contaminated material is continuously fed into the reactor from one end, while the clean material is removed from the other end of the reactor. The atmosphere inside the plasma reactor is maintained neutral or reducing in order to prevent the oxidation of the hydrocarbons. The equipment comprises a feeding system, a static reactor, a rotating reactor, a rotating screw for transporting the residues inside the reactor, a plasma system, a tube for the removal of the volatilized compounds, a condenser located outside the plasma reactor, an exit of clean material from the reactor and a silo for collecting the clean material.

摘要： Method and apparatus for containing, transporting, and storing or disposing of radioactive machinery, including decommissioned nuclear reactor pressure vessels. An improved, economically-produced container is provided which allows easier handling and packaging of machinery within plants where the machinery has been installed, and which provides improved shock absorption and attenuation characteristics, especially when packaging is complete. A reactor pressure vessel or similar item is disconnected from the remainder of the plant and external fittings are trimmed as close to flush with item's exterior as practicable. A storage and containment canister, optionally cut into at least two sections to ease handling and packaging, is placed nearby. The pressure vessel head or any other low-radioactive items are removed, and insulation and other items removed from the outside of the item are placed inside the item's body. The item body is placed into a lower section of the canister and sealed, and detached canister sections are reattached. Gaps between the canister and the RPV body and preferably the interior of the RPV body are filled with grout or low denisity cellular concrete. The canister is closed, and the pressure vessel head or other removed portions are secured to the outside of the canister. Optionally the canister exterior is sealed with a metalizing spray. The complete package is transported for storage or disposal.

摘要： An improved non-thermal plasma apparatus for treating NOx bearing gas streams has a plasma reactor and an inlet and outlet. The plasma reactor is equipped with a plurality of dielectrically-coated electrodes between which a selected voltage is applied to generate a non-thermal plasma environment for driving selected electro-chemical reactions. A predefined voltage is applied across the electrodes to create microdischarges in the exhaust gas stream to convert nitric oxides into primarily nitrogen dioxides. The electrodes are constructed of metal plates, and a fluoropolymeric material, such as fluorocarbon, as the dielectrics. The electrodes are arranged in parallel formation and alternating between positive and negative charges. In one embodiment, fluoropolymeric spacers are positioned between adjacent electrodes and may be configured with selected thicknesses to provide a plurality of desired reaction zones or gaps therebetween. In another embodiment, the electrodes are supported on a specially configured fluoropolymeric (e.g., fluorocarbon) insulators adapted for placement inside the plasma reactor to provide a plurality of gaps. With a plurality of gaps, the total non-thermal plasma environment is expanded to increase the overall flow rate of the exhaust gas or throughput of the apparatus.
