Abstract: This paper provides experimental investigations for optimizing the parameters to work with pilot plant experimental system for achieving maximum SO2 removal efficiency. It is analysed with different absorbers such as, water, NaOH, H2O2 and H2SO4 with different combinations and concentrations. The results reveal that, the removal efficiency acquired is 98.4% by adding 0.1M hydrogen peroxide (H2O2) externally on 0.01M sulphuric acid (H2SO4) solution. From the analysis, polypropylene pall rings with diameter of 15 mm, liquid flow rate of 150 lph, gas flow rate of 40 m3/hr and packed height of 1M are chosen based on their performance in increasing the SO2 absorption rate.
