Lowering Emission using Single Venturi Vacuum in the Wet Scrubber System

Abstract

Abstract: Burning plastic waste using an incinerator will produce emissions of gas that will damage the environment if released casually. This research was conducted to analyze the effect of air flow, water discharge and thickness of the packing media on the efficiency of the wet scrubber in removing emissions from the combustion of plastic waste. There are 3 variable variations, air flow velocity, water flow velocity, and thickness of media with thickness of 5 cm, 10 cm and 15 cm. The parameters to be investigated are the SO2, NO and CO content and temperature at the wet scrubber. The results obtained from the experiments carried out were SO2 efficiency values of 46.80%, CO of 26.70% and NO of 23.68%. SO₂ values tend to have high efficiency values because SO₂ solubility in water is high. In accordance with the effect test with the help of IBM SPSS, water flow and venturi flow greatly influence the removal of NO, CO and SO₂ gases. However, the thickness of the media only affects the removal of CO and SO₂ gases.
