Abstract
Rheology modifying agents and methods of modifying the rheology of a slurry are disclosed. Methods for the prevention of fouling and methods for monitoring the rheology of a slurry are also provided. The slurry can be a lime slurry or a magnesium oxide slurry, for example. The rheology modifying agent can be polymer-grafted nanocrystalline cellulose. The rheology modifying agent can optionally include other components, such as a chelating agent.
