Patent number: 11673115Abstract: 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.Type: GrantFiled: March 22, 2021Date of Patent: June 13, 2023Assignee: Mississippi Lime CompanyInventors: Randy J. Griffard, Gerald K. Bequette, William S. Allebach, Sr., Paul J. Ramer

Publication number: 20220267207Abstract: Systems and Methods to produce a lime hydrate sorbent composition formed of highly reactive lime hydrate (HRH) by adding compounds to the slaking water in a method that would produce a non-HRH, which will typically be a lime hydrate having citric acid reactivity as discussed above of more than ten seconds, to make the non-HRH an HRH, which is having a citric acid reactivity of less than or equal to ten seconds.Type: ApplicationFiled: May 13, 2022Publication date: August 25, 2022Inventors: Randy Griffard, Martin L.

Publication number: 20220105523Abstract: Systems and methods for generation of lime hydrate compounds and particularly highly reactive hydrated lime (HRH) with a reduced resistivity through the inclusion of a sodium compound generally in the slaking water used in generating the lime hydrate or HRH. The compound may then be used in systems which include a Electrostatic Precipitator (ESP) for SO2 mitigation without many of the associated problems in ESP performance.Type: ApplicationFiled: October 18, 2021Publication date: April 7, 2022Inventors: Martin L.
