Abstract

Oppfinnelsen vedrører en fremgangmåte for å behandle hydrofluorsyreholdig gassutslipp (E) omfattende å (a) fange gassutslippene (E), (d) behandle de hydrofiuorsyreholdige gassutslippene (E) ved hjelp av et aluminiumspulver (A) for å fiksere minst en del av hydrofiuorsyren, (e) separere de behandlete gassutslippene (E) og aluminiumspulveret lastet med hydrofluorsyre (Af), (f) resirkulere minst en del av aluminiumspulveret lastet med hydrofluorsyre (Af) i trinn d) for behandling av utslippene (E), hvori fremgangsmåten erved at aluminiumspulveret som er lastet med hydrofluorsyre (Af) utstedt fra separasjonen (trinn (e)) eller er friskt eller blanding derav, fuktes før eller under introduksjon derav i gassutslippsstrømmene (E) som skal behandles.The invention relates to a method for treating hydrofluoric acid-containing gas emissions (E) comprising (a) capturing the gas emissions (E), (d) treating the hydrofluoric acid-containing gas emissions (E) using an aluminum powder (A) to fix at least a portion of the hydrofluoric acid, (e) separating the treated gas emissions (E) and the aluminum powder loaded with hydrofluoric acid (Af), (f) recycling at least a portion of the aluminum powder loaded with hydrofluoric acid (Af) in step d) for treating the emissions (E), wherein the method is in that the aluminum powder loaded with hydrofluoric acid (Af) issued from the separation (step (e)) or is fresh or a mixture thereof, is moistened before or during introduction thereof into the gas emission streams (E) to be treated.
