摘要： A method and device for capturing SO2 present in gases originating from cells for the industrial production of aluminum by igneous electrolysis, implemented over a group of at least two reactors passed through in parallel by a gas stream and supplied with a powdered sorption agent capable of adsorbing effluents present in the gas stream by placing the sorption agent in contact with the gas stream, each reactor having collection elements for collecting the sorption agent after contact with the gas stream, at least one of the reactors having discharge elements for discharging the sorption agent after contact with the gas stream to injection elements for injecting into at least another one of the reactors; and desorbing elements located between the discharge elements and the injection elements, for desorbing the SO2 adsorbed by the sorption agent before it reaches the discharge elements.
