Abstract
Procedure for the absorption of fluorinated compounds in gas mixtures, in particular hf, sif 4, by washing the gas mixture by means of an aqueous solution, characterized in that at least one washing of the gas mixture is carried out by means of water in a first stage. Mode to absorb most of the fluorinated compounds in the form of a solution constituting a first final product, and in a second step, the gaseous mixture obtained after the first stage is washed by a basic aqueous solution in order to absorb the rest of the fluorinated compounds in the form of a diluted solution constituting a second final product, and a purified gas mixture of its fluorinated compounds is evacuated at the outlet of the second stage.
