Hydrated lime is a versatile reagent for Dry Sorbent Injection.  Our testing has shown that Mississippi Lime hydrated lime will neutralize acid gases over a wide temperature range. 

Temperature  Location  Pollutant 
 >2000 F  Boiler  SO2
 >750  Economizer, SCR  SO3, SO2, HCl
 >350  Pre APH  SO3, HCl, SO2
 <350  Post APH  SO3, HCl, SO2

Hydrated lime does not form unstable byproducts or intermediates over the range of temperatures in the above table.  Because of this, injection of hydrated lime can be adjusted to optimize factors such as residence time, particulate collection efficiency, and co-injection of other sorbents (carbon for mercury removal).
