Flue gases proved to have several human and environmental problems. Although they are many, SOX and NOX are the most famous, due to their direct human, animal, and plant effect. Thus, their removal represents one of the main concerns worldwide. Whereas there are several available techniques for this task, herein we applied a unique method through the white/yellow phosphorus (P4). Our target was to achieve the simultaneous removal together with obtaining the complete fertilizer Nitrogen, Phosphorus, Potassium (NPK). The removal efficiency investigated with and without the ozone, SOX and NOX removal reach 100% at a faster time with the ozone existence. Also, examining the optimal P4 weight that was 0.5 g, furthermore, the optimum stirring intensity proves to be 1083 rpm, additionally, the optimum temperature was 55 °C, finally, it was compared with the most famous absorbers. The system efficiency was tested in a special experiment, furthermore, the reaction mechanism was identified together with testing the solid precipitate using Raman spectroscopy and X-Ray Diffraction (XRD).
