  • Patent number: 10369396
    Abstract: An assembly containing a shelf-stable formulation for decontaminating skin exposed to toxic compounds located in a package formed with water and potassium bicarbonate in a first chamber; and a sponge, diacetylmonoxime (DAM), and polyethylene glycol (PEG) located in a second chamber. The package includes a barrier between the first chamber and the second chamber, with the barrier being configured to be rapidly removed when needed to enable the water and potassium bicarbonate to enter the second chamber. The package is made by placing the water and potassium bicarbonate in the first chamber of a package; mixing the DAM with PEG to form a DAM:PEG mixture; infusing the sponge with the DAM:PEG mixture to distribute DAM within the sponge; and placing the sponge, DAM and PEG in a second chamber of the package. Infusing the sponge includes solubilizing the DAM:PEG mixture in ethanol or another low boiling point solvent to form an ethanol-DAM-PEG solution and applying the ethanol-DAM-PEG solution evenly to the sponge.

  • Patent number: 8512215
    Abstract: A waste transformation and destruction apparatus includes a natural gas ignition system, a silica material bed, a heat transfer device, and a system for collecting plasma produced energy. A reaction formed by heat from ignition, carbon from the waste material, supercritical water, —OH radicals, and muons released from the silica bed transform the waste into a fuel. This fuel is more efficiently consumed by the complete combustion process resulting in near total elimination of the waste, increased energy production, and virtually no emissions.

  • Patent number: 8512644
    Abstract: A power generation system for converting organic material into thermal energy and electric power. A reaction of organic material with supercritical water, —OH radicals, and muon methyl radicals are released from a catalytic bed of silica particles in suspended initially transform the organic material into thermal energy. A Nano monomolecular film located on an interior surface of the reaction chamber interacts with plasma formed by conversion of the organic material into thermal energy to produce ion plasma electromagnetic energy. One or more magnetic-coil generators positioned adjacent to the reaction chamber interacts with the electromagnetic energy to produce electric power.

  • Patent number: 8481800
    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.

  • Patent number: 8475080
    Abstract: Provided is a method for remediating arsenic-contaminated soil, including: a collection step of collecting arsenic-contaminated soil; a washing step of adding the collected soil to a washing solution, which is acidic in nature and provides reducing conditions to the soil, so as to remove arsenic from the soil and transfer the removed arsenic to the washing solution; a solid-liquid separation step of separating the soil and the washing solution from each other after the washing step; and a post-treatment step of removing arsenic from the washing solution, which was separated in the solid-liquid separation step, and employing the soil for remediation.

  • Patent number: 8471089
    Abstract: The instant invention relates to a process and plant for the transformation of dangerous wastes containing chromium six as contaminant into non dangerous wastes that can be stored without special care and will be degraded in the environment without time limit. The process basically consists of milling, extracting chromium six in liquid phase and under controlled conditions of stirring, time and temperature, proceeding then, through reduction, to transform the chromium six in chromium three and then precipitating as chromium trioxide, through gasification. The solid resulting from the transformation process can be used as raw material for the manufacturing of firebricks or eventually for the manufacturing of bricks used in the building industry through a process not included in the instant description.

  • Publication number: 20130144103
    Abstract: The present invention is directed to a formulation and associated method for neutralizing one or more toxic chemical and/or materials including toxic industrial chemicals and toxic industrial materials, such as irritants, heavy metals, radioactive metals, acids and acid irritants, pesticides, and various agricultural chemicals, (collectively referred to as toxic chemical, materials, or simply toxins) as well as decontaminating surfaces that have come into contact with these agents. As a result, the formulation of the present invention can be used for neutralizing a broad spectrum of toxic chemicals and materials. In one embodiment, the active ingredient comprises 2, 3, butanedione monoxime (also known as diacetyl monoxime (DAM)), and alkali salts thereof such as potassium 2,3-butanedione monoxime (KBDO). The formulation also typically includes a carrier in which the active ingredient is dispersed.

  • Patent number: 8430803
    Abstract: The present invention discloses a method for solidifying and stabilizing waste acid including steps of condensing waste acid containing phosphoric acid to reduce the volume; mixing the condensed waste acid with waste acid containing fluoroboric acid to solidify and stabilize the mixed waste acid. The pH of the mixed acid is adjusted by adding barium hydroxide as a neutralizer. The efficiency of solidifying waste acid can be improved by partially granulating and by adding solidifying agent indirectly. The method of the present invention can prevent intensely exothermic reaction caused by adding solidifying agents. Furthermore, the method of the present invention is controlled in a temperature of 30 to 45° C. to improve the polymerization of the mixed waste acid so that the efficiency of solidification thereof can be also improved.

  • Patent number: 8430598
    Abstract: Provided is a method of remediating cyanide-contaminated soil. The method is provided to remediate soil contaminated with cyanide and treat the cyanide, which includes collecting the soil contaminated with first cyanide in a solid state and second cyanide in a gaseous or dissolved state, dissociating cyanide by mixing the soil with an alkali washing solution, dissolving the first cyanide in a solid state in the washing solution, and transferring the second cyanide in a dissolved state dissociated from the soil to the washing solution, dissociating the soil from the washing solution, precipitating the first cyanide in a solid state by acidifying the washing solution containing the cyanide, and performing post-treatment on the first cyanide after the first cyanide precipitated in a solid state is dissociated from the washing solution.

  • Patent number: 8420881
    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 deep eutectic solvents or chemically by dissolving Group 1 (alkali metals) or Group 2 (alkaline earth metals) superoxides, e.g. potassium superoxide, in deep eutectic solvents.
