  • Method for inhibiting calcium salt scale
    Patent number: 7300542
    Abstract: Compositions and method of improving inhibition of calcium salt scale formation under the conditions found in chemical pulp processes in which an effective amount of selected phosphonates or phosphonate blends is admixed with the black liquor composition recovered from the digester in a chemical pulping process. The compositions and method are especially well suited for use in the Kraft pulping process.
    Type: Grant
    Filed: January 26, 2005
    Date of Patent: November 27, 2007
    Assignee: Thermophos Trading GmbH
    Inventors: Jacob Owen Thompson, Sheldon Phillip Verrett, Jeremy E. Loy, Steven John Severtson
  • Method for inhibiting calcium salt scale
    Patent number: 7172677
    Abstract: Compositions and method for improving inhibition of calcium salt scale formation under the conditions found in chemical pulp processes in which an effective amount of selected phosphonates or phosphonate blends is admixed with the aqueous digester composition in a chemical pulping process during the digestion stage. The compositions and method are especially well suited for use in the Kraft pulping process.

  • Method for the production of improved pulp
    Patent number: 7097739
    Abstract: Compositions and method for improving properties of pulp produced or reducing the digester cycle time in alkaline chemical pulping processes in which an effective amount of at least one selected phosphonate or carboxylate compound or mixtures thereof is admixed with the alkaline aqueous mixture in the digester of the chemical pulping process. The compositions and method are especially well suited for use in the Kraft pulping process.
