Title (EN) REACTIVE POWDER COMPOSITION AND METHOD FOR PURIFYING GAS
(FR) COMPOSITION REACTIVE PULVERULENTE ET PROCEDE POUR L'EPURATION D'UN GAZ
Abstract:
(EN) The invention concerns a sold reactive powder composition for purifying gas, comprising sodium bicarbonate and an inhibitor of sodium bicarbonate caking, containing coalite and/or a magnesium compound including magnesium (hydr)oxide. The invention also concerns a method for purifying gas which consists in introducing in the gas a reactive composition containing sodium bicarbonate and substantially free of silica, and in subjecting the gas to dust-extraction.
(FR) Composition réactive, solide, pulvérulente pour l'épuration d'un gaz, ladite composition comprenant du bicarbonate de sodium et un inhibiteur d'agglutination du bicarbonate de sodium, comprenant du coke de lignite et/ou un composé du magnésium comprenant de l'(hydr)oxyde de magnésium. Procédé pour l'épuration d'un gaz, selon lequel on introduit dans le gaz une composition réactive comprenant du bicarbonate de sodium et sensiblement exempte de silice, et on soumet le gaz à un dépoussiérage.
