  • Method to optimize temperature profiles displacement batch cooking
    Patent number: 7604711
    Abstract: Method and apparatus for batch displacement digester systems to increase tank farm vessel temperatures for more efficient delignification rates by mitigating the formation of flow channels in the chip bed, minimizing the vertical temperature gradient in the digester and segregation of returning liquors to the tank farm from the digester.
    Type: Grant
    Filed: March 7, 2006
    Date of Patent: October 20, 2009
    Inventor: Craig A. Bianchini
  • Method for mitigating the interference caused by high-molecular weight-by-products in pulping processes
    Patent number: 7282115
    Abstract: Separation of dissolved and colloidal high molecular weight organic by-products from liquors or filtrates in a cellulosic pulping process to improve the overall efficiency of the process.
    Type: Grant
    Filed: November 20, 2003
    Date of Patent: October 16, 2007
    Inventor: Craig A. Bianchini
  • METHOD AND APPARATUS TO DECREASE STEAM CONSUMPTION IN CONVENTIONAL BATCH DIGESTERS
    Publication number: 20060231222
    Abstract: Method and apparatus for conventional batch digesters to retain thermal energy typically lost in the flashing blow operation by transferring the thermal energy to fresh cooking liquors from hot spent cooking liquor.
    Type: Application
    Filed: April 18, 2006
    Publication date: October 19, 2006
    Inventor: Craig Bianchini
  • Method and apparatus to optimize displacement batch cooking using advanced control
    Publication number: 20060201640
    Abstract: Method and apparatus for batch displacement digester systems to increase tank farm vessel temperatures for more efficient delignification rates by mitigating the formation of flow channels in the chip bed, minimizing the vertical temperature gradient in the digester and segregation of returning liquors to the tank farm from the digester.
    Type: Application
    Filed: March 7, 2006
    Publication date: September 14, 2006
    Inventor: Craig Bianchini
  • Method and apparatus to distribute the inflow of liquors in a Batch Digester
    Publication number: 20060157209
    Abstract: Method and apparatus for introducing liquors into a batch digester to produce enhanced or plug-flow of the liquors through the bed of cellulosic material. Wash out liquor can be introduced into the digester during the discharging in a manner to add wash out liquor into the digester and to prevent formation of a vortex of material during discharge.
