Abstract

The invention relates to a method and system for treating flue gases comprising generating a superimposed DC time-varying pulsed wave by superimposing a direct current on a low frequency time-varying pulsating electromagnetic wave signal, providing a treatment medium comprising water, using the superimposed DC pulsed wave to treat the treatment water medium, negatively charging the treated treatment water medium, and passing the negatively charged treated treatment water medium into a chamber containing flue gas such that the negatively charged treated treatment water affects the gas components of the flue gas and converts the gas components respectively to one or more of sulphates, nitrogen, oxygen, bicarbonates, carbonates and carbon, which can then be removed with used treatment water or exhaust gases. In particular, the invention relates to methods and systems for applying a superimposed time-varying frequency electromagnetic wave comprising both AC and DC components in a pulsating manner to enable the removal of pollutant gases from flue gases.
