Abstract:
The present invention provides a method for the treatment of waste comprising one or more hazardous organic components, the method comprising plasma treating a waste in a plasma treatment unit; wherein the waste comprises: (i) a soil and/or aggregate material; and (ii) an oil component; and wherein, before plasma treating the waste, the waste comprises one or more hazardous organic components and from 5 to 50% water by weight of the waste.
Abstract:
The present invention relates to a dust recycling and re-treating system and a method for the same, and in particular, to a dust recycling and re-treating system and a method for the same, which produces dusts generated from an incinerating and melting processing equipment for hazardous wastes, particularly, radioactive wastes, in a slurry form, and recycles and re-treats them within an existing melting furnace.
Abstract:
The invention concerns a method and an installation for treating liquid waste containing water and diluted polluting organic substances, such as pig slurry, or agri-food effluents. The invention is characterised in that it comprises at least: a) a step which consists in thermal evaporation (1) of a substantial proportion of said water; and b) a step (2) which consists in incinerating the concentrate obtained in the preceding step. Preferably, it consists in using a mechanical vapour recompression evaporator (1) combined with an incinerator (2) with fluidised bed and recycling (4) of the heat-exchanging material, in particular sand, and pre-mixing (5) said heat-exchanging material with at least a substantial part of the concentrate (9) obtained in the evaporation step. Said method efficiently destroys the slurry, in particular nitrates, by an inexpensive process, enabling to recuperate its useful elements, among which water with COD
Abstract:
The invention concerns a process for charging solid industrial and hazardous waste into combustion plants, wherein the waste, separated from the combustion chamber (6) by a lock system (5), is comminuted and homogenized in an inert gas atmosphere.
Abstract:
The invention relates to a process and a plant for the thermal treatment of waste materials in which the waste materials (20) are subjected to pyrolysis in a first thermal treatment region (1), the resultant pyrolysis gas is cleared of dust (16) to the extent of at least 90 % and then burned (3). The nitrogen content of the flue gas thus produced may then be either directly removed non-catalytically (5') or catalytically removed (5) after the flue gas has cooled (4). Following possible nitrogen removal, the flue gas is cleaned of pollutants by the addition of correspondingly reactive additives (28) in a filter (6).
Abstract:
In a general aspect, a system can include a reactor for combusting fuel and producing high-temperature, high-pressure liquid as a byproduct, and at least one vessel defining a cavity to be partially filled with water, with an air pocket within the cavity above the water. The system can further include respective valves to control admission of liquid from the reactor into the air pocket when the air pocket has a pressure lower than an operating pressure of the reactor, and to control emission of the water from the at least one vessel through of the vessel after the water in the at least one vessel has been pressurized by the liquid from the reactor. The system can also include a hydroelectric drive system for receiving water emitted from the cavity, and for converting energy in the received water into electrical energy.
Abstract:
This disclosure presents a clean burning flare stack, or gas flare. The gas flare is air assisted to ensure clean burning. The disclosed gas flare provides smokeless clean burning of released gases. For example, the gas flare burns the released gases in a lean burning condition such that sufficient air is supplied to the surges of gases. In addition, the gas flare, by using a low pressure blower mixing chamber, is capable of handling low pressure gases and high pressure gases. As such, different flow rates may be provided to the gas flare when different amounts of low pressure and high pressure flammable gases are mixed with sufficient blower air to provide a clean burning condition. The disclosed smokeless gas flare is thus environmentally friendly and aesthetically appealing.
Abstract:
The disclosure is concerned with generating power using new organic fuel that is generated at wastewater purification plants in the form of sewage sludge with moisture content up to 90-95%. The world supplies this new orgabic fuel in very high quantites that are estimated to be more than 25-40 gr of dry mass/man/day. The new composite fuel comprises a coal suspension with the new dispersed medium, which is the liquid sewage sludge. The composite fuel is introduced into a furnace for combustion and generating power.
