  • Patent number: 11673115
    Abstract: A hydrated lime product exhibiting superior reactivity towards HCl and SO2 in air pollution control applications. Also disclosed is a method of providing highly reactive hydrated lime and the resultant lime hydrate where an initial lime feed comprising calcium and impurities is first ground to a particle-size distribution with relatively course particles. Smaller particles are then removed from this ground lime and the smaller particles are hydrated and flash dried to form a hydrated lime, which is then milled to a significantly smaller particle size than that of the relatively course particles. The resultant lime hydrate product has available CaOH of greater than 92%, a citric acid reactivity of less than 20 seconds, a BET surface area greater than 18, a D90 less than 10 ?m, a D50 less than 4 ?m, a D90/D50 less than 3, and a large pore volume of greater than 0.2 BJH.

  • Patent number: 10221094
    Abstract: A method of providing highly reactive hydrated lime and the resultant lime hydrate where an initial lime feed comprising calcium and impurities is first ground to a particle-size distribution with relatively coarse particles. Smaller particles are then removed from this ground lime and the smaller particles are hydrated, allowed to mature in a damp state, and flash dried to form a hydrated lime, which is then milled to a significantly smaller particle size than that of the relatively coarse particles.
