Abstract

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.
