摘要

The report describes the spray dryer flue gas desulfurization (FGD), which is a throwaway process in which sulfur dioxide (SO2) is removed from flue gas by an atomized lime slurry (Ca(OH)2). The hot flue gas dries the droplets to form a dry waste product, while the absorbent reacts with sulfur dioxide in the flue gas. Dry waste solids are collected in a fabric filter (baghouse) or electrostatic precipitator (ESP) and are typically disposed of by landfill. Descriptions of the process as well as its advantages and costs are included in the report.
