Problem Solving With Continuous Kappa Updates

What can your operators and engineers do with nonstop Kappa readings?

Wood Handling

  • Understand incoming variability or deviations in lignin content and potential quality issues
  • Make informed decisions on sorting, blending or preprocessing which translates into raw material cost optimization
  • Adjust for chip size, moisture content, and cooking parameters

Digesting or Cooking

  • Adjust cooking conditions and time to optimize energy usage while meeting desired lignin target.

Washing and Screening

  • Determine the effectiveness of washing processes and make adjustments
  • Infer possibility of contaminants in pulp after washing and initiate corrective action
  • Analyze real-time data to adjust washing parameters, optimize screen design, and modify washing techniques
  • Evaluate the efficiency of the screening equipment, identify problems, such as blockages or ineffective separation of oversized particles, and initiate corrective actions

Bleach Plant

  • determine under- and over-bleaching conditions and make adjustment to bleaching parameters
  • Track the Kappa at various bleach stages to avoid variations in brightness
  • Detect Kappa deviations that affect quality specs or regulatory requirements and take corrective action

All Through The Pulping Process

  • Overall, determine if pulp meets the targeted quality specification at key points along the journey
  • Determine appropriate chemical dosages for precision control and avoiding excessive chemical usage along the journey
  • Analyze real-time Kappa data to identify trends, correlations, opportunities for process optimization, and better inform root cause analysis,.
  • Analyze real-time Kappa data to assess.

Combining Satron Lumina VCK to measure Kappa with Satron inline Satron Lumina VCB for Brightness and the Satron Lumina VCT for consistency will give a comprehensive measurement solution that  better operator actions and process control.
