Brown stock washing optimization

When a small percentage is worth a million 

Did you know that Total Dissolved Solids is the only measurement that accounts for both inorganics and organics? 

Recent studies show that kraft pulp processing is economically viable only if the BSW stage is operating optimally. Vaisala's process refractometer PR-23-SD for the pulp industry is specially designed for harsh conditions and provide accurate and continuous measurements in all washing stages.

In this eBook we discuss: 

  • Total Dissolved Solids (TDS) as a measurement parameter for Brown Stock Washing, 
  • how TDS can be utilized to reveal the real wash loss, 
  • control strategies and benefits, 
  • TDS measurements in individual washing stages, 
  • advanced process control (APC) with inline TDS measurements by process refractometers.
