Mechanism and process of carbide slag flue gas desulfurization by adding citric acid in spray tower
Abstract：The mechanism and process of carbide slag flue gas desulfurization by adding citric acid in spray tower were studied.The results show that SO2 removal is increased from 58.90% with no citric acid to 77.30% with 5 mmol/L citric acid.The effect of concentration of SO2,temperature,pH value and ratio of liquid-gas were studied.The desulfurization efficiency decreases with inlet concentration of SO2 and temperature and increases with pH value.The ratio of liquid-gas increases from 15 L/m3 to 30 L/m3,the SO2 removal increases from 32.60% to 80.70%,continuing to increase the ratio of liquid-gas,and the SO2 removal decreases.
