Title (EN) METHOD AND DEVICE FOR PROCESSING GASEOUS WASTES IN PARTICULAR CONTAINING A HYDROFLUORIC ACID
(FR) PROCEDE ET DISPOSITIF DE TRAITEMENT D'EFFLUENTS GAZEUX CONTENANT EN PARTICULIER DE L'ACIDE FLUORHYDRIQUE
Abstract: front page image
(EN)The invention relates to a method for processing hydrofluoric acid-containing gaseous wastes (E) consisting (a) in capturing said gaseous wastes (E), (d) in processing said hydrofluoric acid-containing gaseous wastes (E) by means of an alumina powder (A) for fixing at least one part of hydrofluoric acid, (e) in separating the processed gaseous wastes (E) and the alumina powder loaded with the hydrofluoric acid (Af), (f) in recycling at least one part of said alumina powder loaded with the hydrofluoric acid (Af) at stage d) for processing said wastes (E), wherein said process is characterised in that the alumina powder which is loaded with the hydrofluoric acid (Af), obtainable by the separation (stage (e)) of is fresh of by the mixture thereof, is humidified prior to or during the introduction thereof into said processable gaseous wastes (E).
(FR)L'invention concerne un procédé de traitement d'effluents gazeux (E) contenant de l'acide fluorhydrique, dans lequel successivement (a) on capte lesdits effluents gazeux (E) ; (d) on traite lesdits effluents gazeux (E) contenant de l'acide fluorhydrique au moyen de poudre d'alumine (A), ladite poudre d'alumine (A) fixant au moins une partie de l'acide fluorhydrique ; (e) on sépare les effluents gazeux traités (Et) et la poudre d'alumine chargée d'acide fluorhydrique (Af) ; (f) on recycle au moins une partie de ladite poudre d'alumine chargée d'acide fluorhydrique (Af) dans l'étape d) de traitement des effluents (E) ; ledit procédé étant caractérisé en ce que ladite poudre d'alumine, chargée d'acide fluorhydrique (Af) issue de la séparation (étape (e)) ou fraîche ou un mélange des deux, est humidifiée avant ou pendant son introduction dans le flux desdits effluents gazeux (E) à traiter.
