Title (EN) METHOD FOR PURIFYING A GAS CONSISTING OF ACID COMPOUNDS
(FR) PROCEDE D'EPURATION D'UN GAZ EN COMPOSES ACIDES
Abstract: front page image
(EN)The invention concerns a method for purifying a gas consisting of acid compounds which consists in subjecting the gas to a dry or semi-wet treatment with a basic reagent comprising an anhydrous sodium carbonate powder, with specific surface area greater more than 2 m?2¿/g, which while it is being handled, is maintained in an atmosphere with relative humidity less than 20 % and/or to which a desiccant has been added.
(FR)Procédé pour l'épuration d'un gaz en composés acides, selon lequel on soumet le gaz à un traitement par voie sèche ou semi humide avec un réactif basique comprenant une poudre de carbonate de sodium anhydre, de surface spécifique supérieure à 2 m?2¿/g qui, pendant sa manutention, est maintenue dans une atmosphère présentant une humidité relative inférieure à 20 % et/ou est additionnée d'un agent dessicant.
