20090107363 | Mortar Composition, Method of Preparation Thereof and Use Thereof - A mortar composition in the form of a dry powder, ready for use, comprising at least one powdery binder and at least one aggregate, as well as possibly at least one standard additive and/or adjuvant, and formed from particles, at least some of which, referred to as fine particles, are liable to produce an emission of dust, characterized in that it also comprises a fluid additive that consists of least one non-polar hydrocarbon organic substance and that has a capacity for agglomeration of the said fine particles, and in that the dry mortar composition comprises agglomerates of fine particles formed by the fluid additive. | 04-30-2009 |
20100024598 | PROCESS FOR THE TREATMENT OF CONTAMINATED METAL RESIDUES AND APPARATUS FOR IMPLEMENTING IT - Process and apparatus for the treatment of divided metal residues contaminated by one or more organic compounds, comprising: mixing, inside a chamber, of said metal residues with at least one calcium/magnesium compound capable of reacting exothermically with water; exothermic reaction of said at least one calcium/magnesium compound with the water that the metal residues contain; rise in temperature of the metal residues subject to an exothermic reaction; dehydration of said metal residues during this exothermic reaction; oxidation of the organic compounds during said mixing, by bringing the metal residues contaminated by one or more organic compounds mixed with said at least one calcium/magnesium compound into contact with a gas stream containing at least partly oxygen; and removal from the chamber of a handleable dehydrated treated product having a residual content of organic compounds of less than 1% by weight of said treated product. | 02-04-2010 |
20120134903 | Solid Inorganic Composition, Method for Preparing Same, and Use Thereof for Reducing Dioxins and Heavy Metals in Flue Gas - The invention relates to a solid inorganic composition for reducing dioxins and furans, as well as heavy metals, in particular mercury, present in flue gases, to a method for preparing such a composition, and to the use thereof for reducing dioxins and furans as well as heavy metals, in particular mercury, present in flue gases, by contacting said flue gases with said solid inorganic composition. | 05-31-2012 |
20120167762 | Solid Mineral Composition, Method for Preparing Same and Use Thereof for Reducing Heavy Metals in Flue Gas - The invention relates to a solid mineral composition of heavy metals, in particular mercury, in flue gas, to a method for preparing such a solid mineral compound and to the use thereof for reducing heavy metals, in particular mercury, in flue gas, by placing the flue gas in contact with the solid mineral composition. | 07-05-2012 |
20140205751 | MORTAR COMPOSITION, METHOD OF PREPARATION THEREOF AND USE THEREOF - A mortar composition in the form of a dry powder, ready for use, comprising at least one powdery binder and at least one aggregate, as well as possibly at least one standard additive and/or adjuvant, and formed from particles, at least some of which, referred to as fine particles, are liable to produce an emission of dust, characterised in that it also comprises a fluid additive that consists of least one non-polar hydrocarbon organic substance and that has a capacity for agglomeration of the said fine particles, and in that the dry mortar composition comprises agglomerates of line particles formed by the fluid additive. | 07-24-2014 |
20150184078 | Mixed Calcium and Magnesium Compound and Method for Producing Same - A method for producing a mixed calcium and magnesium compound comprising the slaking of quicklime with a magnesium hydroxide suspension, forming solid particles, said slaking by non-wet means forming said solid particles comprising a calcium phase and a magnesium phase intimately bonded to each other and of homogeneous volume distribution, and a mixed compound comprising a calcium phase and a magnesium phase. | 07-02-2015 |
20160129394 | Method and Device for Treating Gas By Injecting a Powdered Compound and an Aqueous Phase - The invention relates to a method for treating a gas comprising the following steps: injecting a powdered compound into the gas line, injecting an aqueous phase in droplet form into said line, capturing pollutants from the gases, and recovering said powdered compound separately. The step for injecting an aqueous phase in droplet form is done so as to moisten those particles of powdered compound in the gas line, when they are injected. | 05-12-2016 |
