ABSTRACT:
Novel hydrated-lime slurry compositions are disclosed, which include a heat-stable polymeric dispersant. The polymeric dispersant is capable to withstand temperatures in excess of 212° F. experienced by the slurry as a result of the hydrolysis of quicklime to produce hydrated lime, and accordingly can be added to the slurry composition prior to the addition of quicklime. Methods for making such slurry compositions are also disclosed.
