Abstract

A method of operating an apparatus for the cleaning of industrial waste gases and especially power plant flue gases. The gases are fed through a quencher to a first scrubber with its own recirculation and upstream of a second scrubber having its own recirculation and aerosols of halogen compounds which are eliminated by providing the quencher is part of a prescrubber or by forming the downstream scrubber with a wet electrostatic precipitator.
