The simultaneous removal of sulfur dioxide and hydrogen chloride from flue gas generated by municipal waste incineration is a process that is now receiving considerable attention. A dry scrubbing process using a spray dryer absorber (SDA) has recently become an attractive alternative to wet scrubbing. In this operation flue gas is introduced at the top of the SDA and flows downward concurrently with the injected lime-water slurry. This study presents a mathematical model describing the various processes which occur in the SDA system and compares model predictions with experimental results from a 2.3 m diameter pilot plant SDA. The process model in the wet stage is a three phase, gas-liquid-solid, reaction system The limiting conditions for SO2 removal may be gas film resistance, solid dissolution rate, or combined resistances. Limiting conditions for HC1 removal are similar. The liquid phase reactions are considered instantaneous. The process is modeled by an adiabatic two phase system. |
