Based on the demand of sintering/pelleting flue gas ultra-low emission, a semi-dry method using a spray dryer absorber (SDA) combined with O 3 oxidation was proposed for simultaneous removal of SO 2 and NO. Effects of O 3 injection site, O 3 /NO molar ratio, and spray tower temperature on the removal efficiencies were investigated. It was revealed that …

(LSFO) — a wet FGD technology and Lime Spray Dryer (LSD) — a semi-dry FGD technology which employs a spray dryer absorber (SDA). In wet FGD systems the polluted gas stream is brought into contact with a liquid alkaline sorbent (typically limestone) by forcing it through a pool of the liquid slurry or by spraying it with the liquid.
