Experimental study of the removal NO and SO from flue gas using the O/HO, and O/UV processes.

The study investigates the effect of different parameters for the removal of SO and NO through a wet process concurrently. Two separate processes have been compared for the removal of flue gases, that is, Ozone/UV and HO/UV. The research aims to develop a comparative study for the removal of SO and NO simultaneously using Ozone/HO and UV light and find the energy consumption (also known as ) for each process. Combining UV with O and HO play a crucial role in generating hydroxyl radicals. Different combinations of Ozone/HO, flue gas, and UV intensity were studied at different pH and temperatures of the solution to achieve maximum removal of the flue gases. For, the ozonation process it was observed that the removal% of flue gases increases with increasing UV intensity, and at higher UV intensity (250 W), the removal% for NO is 92% and SO is 95% simultaneously at optimum temperature 308 K. For HO/UV process (250 W UV intensity), removal% for NO is 95% and SO is 100% at 313 K, 0.3 LPM flow rate of flue gases. The values obtained for both processes were less than 1 for 95% NO/SO removal efficiency.
