Abstract: The present invention discloses a nonhomogeneous soil pollutant multiphase extraction and tail gas purifying device and an application method thereof. The device comprises two water retaining walls, a water layer extraction system and a near-water soil layer extraction system, a nonhomogeneous soil layer extraction system and a geophysical prospecting system, etc. The distribution of pollutants and the range of the pollution plume can be determined through geophysical prospecting, borehole exploration, three-dimensional simulation, etc.; through the combined application of the water retaining wall and the water pumping and supplementing self-circulation system, it is beneficial to form a stable treatment area for the occurrence area of the groundwater layer; the arrangement of the water layer extraction system facilitates the liquid extraction of the organic pollutants in a free phase and a dissolved phase at the groundwater.

Abstract: An improved oxidation process may be used to oxidize a wide variety of feedstocks. Oxidation takes place in a reactor where the feedstock is mixed with an oxidizing acid, such as nitric acid. The reaction mixture may also include another oxidizing acid such as sulfuric acid.

Abstract: A process for treating waste includes reacting an organic feedstock in a reactor. The organic feedstock is part of a reaction mixture that includes a first oxidizing acid (e.g., sulfuric acid) and nitric acid. In one embodiment, the reaction mixture, excluding solids, includes no more than 7.5 wt % of the total of the first oxidizing acid and the nitric acid. In another embodiment, the reaction mixture, excluding solids, includes no more than 1 wt % nitric acid. In another embodiment, the process includes separating heavy metals from the effluent.

Abstract: The subject invention provides a potentially economically viable process for the destruction of small to large quantities of sulfur and nitrogen mustards and lewisite, their homologous/analogues, and similar chemical warfare agents at ambient conditions without producing any toxic by-products. The process uses the superoxide ion that is either electrochemically generated by the reduction of oxygen in ionic liquids or chemically by dissolving Group 1 (alkali metals) or Group 2 (alkaline earth metals) superoxides, e.g. potassium superoxide, in ionic liquids.

Abstract: An improved oxidization process may be used to oxidize a wide variety of feedstocks. Oxidation takes place in a reactor where the feedstock is mixed with an oxidizing acid, such as nitric acid. The reaction mixture may also include a secondary oxidizing acid such as sulfuric acid as well as water and/or dissolved and mechanically mixed oxygen gas. The reactor may be maintained at an elevated pressure such as at least approximately 2070 kPa or desirably at least approximately 2800 kPa. The temperature of the reaction mixture may be maintained at no more than 210° C.

Abstract: High energy reaction of halogen-containing carbon, boron, silicon and nitrogen compounds, with base component comprising at least one atom selected from Groups IA to VIA, transition metals, lanthanides and actinides of the Periodic Table of the Elements, excluding aluminum and aluminum oxide.

Abstract: The subject invention provides a potentially economically viable method for the preparation of hydrogen peroxide (H2O2) in deep eutectic solvents (DES). H2O2 is then used for the destruction of small to large quantities of sulfur and nitrogen mustards and lewisite, their homologous/analogues, and similar chemical warfare agents at ambient conditions in DES without producing any toxic by-products. Furthermore, H2O2 has been used for the destruction of small to large quantities of halogenated hydrocarbons, their homologous/analogues, and similar hazardous chemicals at ambient conditions. H2O2 can be formed by either the electrochemical reduction of oxygen in DES in the presence of water or by dissolving Group 1 (alkali metals) or Group 2 (alkaline earth metals) superoxides, e.g. potassium superoxide, in DES in the presence of water, with/without chemicals used for the enhancement of the solubility of the metal superoxide in the DES, e.g. crown ethers.

The at least one drug-retaining region may be configured to retain a drug. The at least one energy source may be configured to transmit energy to the drug. The drug is capable of being rendered ineffective in the presence of the transmitted energy.

Abstract: A moving bed reactor system is provided. The system comprises at least one gas inlet, a distributor, a temperature control, a plurality of electrodes, and a spark control circuit. The spark control circuit drives the electrodes and generates a multi-arc discharge when the system is loaded with particles and a gas at approximately atmospheric pressure or greater is being pumped through the system. The multi-arc discharge is useful to create activated species which may improve the rate of a chemical reaction taking place in the moving bed reactor system.

Abstract: Hydrogen peroxide is vaporized (20) and mixed (30) with ammonia gas in a ratio between 1:1 and 1:0.0001. The peroxide and ammonia vapor mixture are conveyed to a treatment area (10) to neutralize V-type, H-type, or G-type chemical agents, pathogens, biotoxins, spores, prions, and the like. The ammonia provides the primary deactivating agent for G-type agents with the peroxide acting as an accelerator. The peroxide acts as the primary agent for deactivating V-type and H-type agents, pathogens, biotoxins, spores, and prions. The ammonia acts as an accelerator in at least some of these peroxide deactivation reactions.

Abstract: The invention relates to a method for removing inorganic compounds from a section of soil. By regulating an electric voltage applied between two or more electrodes (1, 2) disposed in the section of soil (3) to values equal or below the electrokinetic point (61), inorganic compounds are electrochemically modified in situ in such a manner that they are electrokinetically mobilized and can be directly deposited on the electrodes (1, 2). According to the invention, the electrokinetic point (61) is adjusted and reached by applying a voltage to the electrodes (1, 2) and controlling it, once, after passing a first current/voltage zone (62) of a first gradient, a second current/voltage zone (63) of a second gradient that is smaller than the first gradient is reached.
