Simultaneous Removal of SOx and NOx Using a High-Gravity Reactor

In an era where urbanization and industrialization are on the rise, the consequences of air pollution have become increasingly prevalent and concerning. The air we breathe, once considered to be a limitless resource, is now laden with pollutants that pose significant risks to human health. The main sources of air pollutants include sulfur oxides (SO_x), nitrogen oxides (NO_x), and particulate matter (PM), which are all extremely harmful to the environment and human health and emerge from industrial operations and automobile emissions. Although there are traditional cleanup methods, HiGee technology provides more effective pollutant capture. Flue gases from a coal-based power station were treated in this study using a high-gravity reactor installed with variable porosity packing. Under various operating conditions, such as rotor speed (rpm), caustic dosing rate, and gas–liquid flow rates, a caustic solution functioned as the absorbent medium. High centrifugal forces and better gas–liquid contact allowed for enhanced mass transfer, which was responsible for the results’ near-complete elimination of SO_x and NO_x. Furthermore, substantial PM reduction and selective absorption were achieved, highlighting the potential of HiGee Technology in flue gas treatment.
