Abstract
Hydrochloric acid (HCl) is a common acidic pollutant present in the flue gas of most municipal and hazardous waste incinerators. Hydrated lime [Ca(OH)2] is often used as a sorbent to remove HCl through the dry and semidry scrubbing process. However, this process provides a very short residence time for the lime and HCl to react, causing the lime conversion efficiency to be low and generating a large amount of fly ash. Following our previous studies on the kinetics of the HCl−lime reaction, the current paper is aimed at the investigation of the effects of other species present in the flue gas, namely, CO2, SO2, and moisture, on the HCl−lime reaction. The reaction was carried out in a thermogravimetric analyzer at a temperature of 200 °C under 9% of O2, and the products of the reaction were identified and quantified using X-ray diffraction. The sequential reactions of lime with CO2 (or SO2)−HCl−CO2 (or SO2) were also conducted to compare the different effects of these species on the formation of product lay...
