| 20100160709 | PROCESS AND APPRATUS FOR WASTE TREATMENT - The present invention relates to processes and apparatus for improving municipal waste treatment in autoclave processes. Improvements relate to the use of air-waste stream treatment, indirect heating with thermal fluid, forced steam transfer, autoclave design, waste treatment of contaminated air,classifiers for better separation of fibres from glass or grit and processing. The improvements allow more efficient, safer and environmentally friendly processing, and better end products. | 06-24-2010 |
| 20100234667 | Method and plant for treatment of asbestos-containing waste materials in supercritical water - A method for destroying asbestos in mainly organic matrix asbestos-containing waste (ACW), which includes the steps of: preparing the asbestos-containing waste; preparing a supercritical aqueous phase; allowing asbestos and the primarily organic matrix of the asbestos-containing waste to react with the aqueous phase for a time t in an appropriate reactor at predetermined pressure P and temperature T to maintain the aqueous phase in supercritical conditions; cooling and condensing the aqueous phase flowing out of the reactor; and separating said aqueous phase from any entrained solid product therein. The step in which the supercritical aqueous phase is prepared includes an additional step, in which at least one oxidizing compound is added in a predetermined concentration C | 09-16-2010 |
| 20120184797 | PROCESS AND APPARATUS FOR THE THERMAL TREATMENT OF REFINERY SLUDGE - A continuous process for the thermal treatment of a refinery sludge, comprising the following operations: a. drying of the refinery sludge, possibly mixed with pet-coke, at a temperature ranging from 110 to 120° C.; b. gasification of the dried sludge, at a temperature ranging from 750 to 950° C., for a time of 30 to 60 minutes, in the presence of a gas containing oxygen and water vapour, with the associated production of synthesis gas (CO+H | 07-19-2012 |
| 20140051902 | PROCESS FOR ELIMINATING OR REDUCING PERSISTENT ORGANIC POLLUTANTS CONTAINED IN PARTICLES - A treatment process of persistent organic pollutants contained in particles is provided. Said process includes reacting persistent organic pollutant in particles under hydrothermal conditions in the presence of Fe | 02-20-2014 |
| 20140206921 | COMPOSITIONS AND METHODS FOR REMEDIATION OF CHLORINATED POLYAROMATIC COMPOUNDS - The present invention relates to compositions and methods that are effective in the remediation of contaminants found in natural sources such as groundwater, surface water, soil and manufactured products. The disclosed compositions and methods provide a method for remediating chlorinated polyaromatic compounds by treating them under pressure and heat with concentrated acids and chloride salts. After decomposition has occurred, the resulting acid that is produced is made dermal and non-corrosive. The compositions and methods claimed herein make the product safe to be in contact with humans and animal tissue without causing injury. | 07-24-2014 |
| 20140364676 | System and Method for Hydrothermal Reaction - A system for hydrothermal reaction comprises a heater ( | 12-11-2014 |
| 20150321038 | METHODS AND EQUIPMENT FOR HYDROTHERMAL PROCESSING AND DISPOSAL OF HIGHLY TOXIC SUBSTANCES, WASTE AND METAL POWDERS - A method of hydrothermal processing of highly toxic substances, wastes and metal powders, comprises a batch processing cycle of at least following steps i. to viii: i. preparing a batch of highly toxic waste, substances and metal powders for processing; ii. applying precision dozing to the batch to obtain a mixture of the batch with water and at least one additional reagent in preset proportions; iii. feeding the mixture into a reactor; iv. spraying the mixture inside the reactor with a mechanical spray nozzle; v. supplying an additional oxidizing agent inside the reactor; vi. adjusting a temperature inside the reactor to above 374.2° C.; vii. adjusting a pressure inside the reactor to above 21.8 MPa, thereby driving the water into supercritical condition and initiating a supercritical hydrothermal oxidation process; and viii. keeping the mixture in the reactor for a preset amount of time, and at the same time. The method further comprises removing a produced steam and hydrogen mixture from the reactor via a steam-gas unit and droplet separator into a wastewater condenser unit and a gas drainage pipe, and venting suspended solids through a bottom part of the reactor into a solids collector unit. The method then provides the steps of repeating the batch processing cycle after it has terminated; and monitoring and controlling the temperature and pressure inside the reactor via an Automatic Process Control System (APCS) during all steps. | 11-12-2015 |
| 20160051851 | Devices for Treating Medical Waste and Methods of their Use - Disclosed and claimed herein are devices for the treatment of medical waste using high temperature and pressure steam. The devices combine both the sterilization chamber and the steam generating component. The devices may be self-contained and may be movable by one person of average strength and ability. The devices which are self-contained require no special installation, connections, plumbing or permanent or semi-permanent electrical connections. Disclosed and claimed herein are methods using the disclosed and claimed devices. | 02-25-2016 |
