<p>The decontamination process is characterised in that the gaseous effluents are burnt with hydrogen in a modified plant for the synthesis of HCl which comprises a burner (1) in a furnace (2), an absorber (3) and a tail column (5) and in that, so as to maintain the flame temperature at a sufficiently low temperature, the gaseous effluents to be decontaminated are diluted, at the burner inlet, with a flow of inert recycling gas (21) originating from the outlet of the tail column (5) and circulated with the aid of a fan (19). <IMAGE></p> |
