  • Method of modeling and control for delignification of pulping
    Patent number: 5060132
    Abstract: A method and apparatus for controlling the delignification process by monitoring and minimizing variations in the Kappa Number and the digester residual chemical concentration. A parameter representative of the H factor for the delignification process and a measurement of the initial chemical concentration are utilized to produce signals representative of the actual Kappa Number and the residual acid concentration in the digester. The expected perturbations in Kappa Number and the residual chemical concentration are compared with target values for same to produce estimated errors due to mismatch which are compared with actual measured errors for these parameters to produce compensated control errors for same.
    Type: Grant
    Filed: December 7, 1989
    Date of Patent: October 22, 1991
    Assignee: Elsag International B.V.
    Inventors: Jeffrey A. Beller, Ralph K. Johnson, Roger Kammerer, Azmi Kaya, Marion A. Keyes, IV
  • System for modeling and control for delignification of pulping
    Patent number: 5032977
    Abstract: A method and apparatus for controlling the delignification process by monitoring and minimizing variations in the Kappa Number and the digester residual chemical concentration. A parameter representative of the H factor for the delignification process and a measurement of the initial chemical concentration are utilized ot produce signals representative of the actual Kappa Number and the residual acid concentration in the digerter. The expected perturbations in Kappa Number and the residual chemical concentration are compared with target values for same to produce estimated errors due to mismatch which are compared with actual measured errors for these parameters to produce compensated control errors for same.
