So2-Scrubber Technology : Double Alkali Mode, Krishna K. Rao
Theses
Double alkali (D/A) processes for the desulfurization of flue gases occupy an increasingly important role in applied technology.
D/A processes involve two steps, namely, scrubbing and regeneration. In the scrubbing step, the alkali (Na2SO3) reacts with SO2. In the regeneration step the acid formed, NaHSO3, reacts with an alkali to regenerate Na2SO3.
This study was focused on the regeneration step. Regenerants investigated were slurries of lime and limestone. The major factors studied were reactor configuration and mixing patterns.
These systems were investigated in a batch, backmix, and plug-flow …
