  • Patent number: 10570347
    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.

  • Patent number: 9290620
    Abstract: The invention provides a method of efficiently producing branched, cyclic glycerol-based polyols with a co-product as anti-biodegrading agent from inexpensive readily available glycerol monomer. The method involves polymerizing glycerol or glycerol with at least another monomer to multiple other monomers in the presence of particular amount of a strong base as the catalyst under a particular distillation environment. The polyol produced by the inventive method is beneficial of reducing scales in Bayer liquid for aluminum production process and improving brightness of coated paper substrates without greening effect.

  • Patent number: 9102995
    Abstract: The invention provides methods and compositions for improving the production of alumina hydrate. The invention involves adding one or more cross-linked ethylsulfonated polysaccharides to liquor or slurry in the fluid circuit of the production process. The one or more polysaccharides include cross-linked dextran or cross-linked dihydroxypropyl cellulose. The various polysaccharides can impart a number of advantages including at least some of: greater flocculation effectiveness, increasing the maximum effective dosage, faster settling rate. The production process can be a Bayer process.

  • Patent number: 8753480
    Abstract: The current invention includes a composition having stability additives of selected inorganic salts and/or organic incorporated into an aldehyde-functionalized polymer product. The stability additive can be post added to the finished polymer product, added to the reaction vessel prior to inducing functionalization of the non-functionalized polymer, or added at any stage during the functionalization reaction. Methods for forming the composition and using the composition to produce a cellulosic fiber-based medium are also disclosed.
