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 SO₂absorption rate.
