Lime for Dry Scrubbing - Carmeuse



Spray Dryer Absorption (SDA) is a dry scrubbing process that is generally used for low-sulfur coal. SDA FGD systems are typically located after the air preheaters, and the waste products are collected either in a baghouse or electrostatic precipitator. Flue gas is treated in an absorber by mixing the gas stream concurrently with atomized lime slurry droplets.

The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.
