Method and system for applying superimposed time-varying frequency electromagnetic wave for removal of SOX, CO2 and NOX from flue gases

A system for removing gas components SOx, NOx, and CO2 together from flue gas, the system comprising:

• a container containing a treatment medium;
• a device for generating a superimposed DC time-varying pulsed wave and having at least two output terminals, the device comprising an alternating current (AC) wave generator for generating an AC driving signal of AC electromagnetic wave having a time-varying frequency at a desired sweeping time, and a direct current (DC) biasing unit electrically coupled in series with the AC wave generator and for producing a DC output with a predefined DC bias voltage, the DC biasing unit being configured such that the DC output is mixed with the AC driving signal to produce the superimposed DC time-varying pulsed wave in which the time-varying frequency AC wave is riding on the predefined DC bias voltage, and an emitter provided at one or each of both of a first excitation site and a second excitation site in the treatment medium or in the treatment medium and the treatment medium container and electrically coupled in series with the output terminal of the device, for transmitting the superimposed DC time-varying pulsed wave to the treatment medium, wherein the device is electrically coupled in series with the first excitation site and the second excitation site in the treatment medium or in the treatment medium and the treatment medium container directly or through the emitter, such that the superimposed DC time-varying pulsed wave is applied to the treatment medium or in the treatment medium and the treatment medium container, and wherein the DC bias output and the AC driving signal are superimposed such that the superimposed DC time-varying pulsed wave is able to induce a flow of ionic current having a DC component travelling in a pulsating and time-varying manner in the treatment medium or in the treatment medium and the treatment medium container and effect induced vibration of electrons and molecules of the treatment medium and creation of electron-carrying (H2O)n− clusters in the treatment medium;
• a chamber containing flue gas and having a treatment medium inlet and a treatment medium outlet;
• means to pass the thus treated treatment medium through the inlet into the flue gas chamber;
• and
• means to remove the treatment medium from the water medium outlet.
