588401000 | Chemical warfare substances, e.g., cholinesterase inhibitor (EPO/JPO) | 1 |
20080242913 | TREATMENT OF CHEMICAL AGENT HYDROLYSATES - The present invention relates generally to the destruction of chemical weapons. In particular, the present invention relates to methods for treating hydrolysates of chemical agents. In one embodiment, the present invention provides a method comprising oxidizing a hydrolysate of a chemical agent to produce an aqueous layer and an organic layer, the aqueous layer comprising an organophosphorus concentration and the organic layer comprising an organosulfur concentration, and separating the organic layer from the aqueous layer. | 10-02-2008 |
588403000 | Explosives, propellants or pyrotechnics, e.g., rocket fuel, napalm (EPO/JPO) | 3 |
20090131733 | Blasting system and blasting method - The object is to rapidly clean-up an off-gas generated by blasting in a pressure vessel to such a level as to permit the exhaust of the off-gas. An object to be blasted is blasted in a pressure vessel to generate an off-gas, which is introduced into a combustion furnace to burning a combustible component contained in the off-gas. The off-gas after the burning in a reservoir section is stored in the reservoir section, and exhausted out of the reservoir section if a component contained in the off-gas complies a predetermined emission requirement, otherwise returned to at least one of the pressure vessel and the combustion furnace to be re-treated if the component does not comply the emission requirement. | 05-21-2009 |
20130345488 | ORGANIC NITRATE EXPLOSIVE TREATMENT SYSTEM - The present Treatment System ( | 12-26-2013 |
20140323792 | DESENSITIZING EXPLOSIVE MATERIALS USING A VACUUM VESSEL - A system and method for desensitizing an explosive material using a vacuum vessel having an enclosed volume. The explosive material is placed in the enclosed volume of the vacuum vessel, and immersed in a desensitizing liquid also in the enclosed volume. The pressure in the enclosed volume is reduced with respect to atmospheric pressure conditions to at least partially saturate the explosive material with the desensitizing liquid. | 10-30-2014 |
588405000 | Organic substances (EPO/JPO) | 2 |
20100274069 | METHOD FOR BIOREMEDIATION OF HIGHLY AROMATIC HYDROCARBON WASTES - Disclosed herein is a method for biopile-based bioremediation of hydrocarbon waste with high aromatic content. The method comprises of isolating specific microorganisms and preparing microbial blend, preparing biopile, adding the microbial blend into the biopile, providing nutrient, aeration and watering of biopile. | 10-28-2010 |
588409000 | Containing oxygen, sulfur, selenium or tellurium, i.e., chalcogen (EPO/JPO) | 1 |
20100160710 | METHODS AND APPARATUSES FOR REDUCING EMISSIONS OF VOLATILE ORGANIC COMPOUNDS FROM PUMPS AND STORAGE TANKS FOR VOC-CONTAINING FLUIDS - A method is provided for reducing emissions of a volatile organic compound (“VOC”) from a source of the VOC. The method includes the steps of: (A) operatively positioning a VOC-absorbing material between the source of the VOC and the atmosphere, wherein the VOC from the source of the VOC must pass through the VOC-absorbing material before being vented to the atmosphere, and wherein the VOC-absorbing material comprises: (i) a permeable substrate; and (ii) a stripper for the VOC; and (B) exposing the stripper of the VOC-absorbing material to bacteria, wherein the bacteria is selected for being capable of converting the VOC to another compound. A method for pumping a fluid from a low-pressure fluid source to a high-pressure fluid outlet and a method for storing or transporting a fluid are also provided, wherein the fluid comprises a VOC. | 06-24-2010 |
588410000 | Inorganic substances (EPO/JPO) | 3 |
588412000 | Containing heavy metals, in the bonded or free state (EPO/JPO) | 3 |
20080255402 | SYSTEM FOR SEPARATING AND EXTRACTING HEAVY METALS FROM POLLUTED LIQUID WASTE - A system for separating and extracting heavy metals from polluted liquid waste includes a pressurizing unit for pressurizing an extracting solvent using a high-pressure gas, so that the extracting solvent contains supersaturated air and is then jetted into a pneumatic stirring, reacting and separating apparatus, in which the supersaturated air in the extracting solvent instantaneously leaches out to thereby produce a large quantity of micro-sized extracting solvent-bearing bubbles that react with heavy metal-polluted liquid waste contained in the pneumatic stirring, reacting and separating apparatus to separate heavy metals from water. A gas supplying device is connected to and supplies gas to the pneumatic stirring, reacting and separating apparatus to stir the heavy metal-polluted liquid waste. And, a pumping unit is connected to the pneumatic stirring, reacting and separating apparatus to pump out heavy metal-separated water to achieve the object of removing heavy metals from liquid waste. | 10-16-2008 |
20090054719 | SYSTEM AND METHOD FOR RECYCLING OF LEAD FROM LEAD-BASED PAINT WASTE - A transportable process for the oxidation of deconstruction and demolition debris contaminated with lead-based paint that includes sizing and heating waste for a predetermined period of time and at a temperature in the range of 500° to 1,200° C. The process results in concentration of the lead in a small volume of product possessing physical and chemical properties that promotes recycling of the lead rather than disposal of the lead in landfills. | 02-26-2009 |
20100292525 | Method of processing waste material - An aspect of the present invention is a method of processing a waste material that contains mercury or a mercury compound, and chlorine or a mercury chloride, the method including a step of adding a chlorine scavenger to the waste material, and stowing the waste material in a treatment vessel; and a step of subjecting the waste material to a blasting treatment by fitting an explosive to the treatment vessel and detonating the explosive inside a pressure-proof container. | 11-18-2010 |
