  • Rheology modifying agents for slurries
    Patent number: 10017624
    Abstract: Rheology modifying agents and methods of modifying the rheology of a slurry are disclosed, in addition to methods for the prevention of fouling. The slurry can be a lime slurry or a magnesium oxide slurry. The rheology modifying agent can be a low molecular weight anionic polymer, a high molecular weight polymer, a mixture of a low molecular weight anionic polymer and a high molecular weight polymer, a mixture of a high molecular weight polymer and a chelating agent, and a mixture of a chelating agent, a high molecular weight polymer, and a low molecular weight anionic polymer.
    Type: Grant
    Filed: April 18, 2017
    Date of Patent: July 10, 2018
    Assignee: ECOLAB USA INC.
    Inventors: Jasbir S. Gill, Tzu Y. Chen, Reagan Faith, Adam Coulterman
