Minimize Shutdowns & Safety Concerns

Access Real-Time Data for Mill Production Optimization

As the pulp industry tansitions towards greater energy efficiency and lower carbon emissions, reducing energy and water use and minimizing production costs is of ever greater interest. Monitoring black liquor is one of the critical areas where mills can optimize energy production during evaporation and in recovery boilers, but it must be closely controlled to guarantee safety.

The Vaisala Polaris™ PR53SD process refractometer is designed for measuring total dissolved solids and other concentrations in pulp mill fiber and chemical recovery lines. The key features of this purpose-built instrument include:

Design in compliance with the BLRBAC Recommended Good Practice Safe Firing of Black Liquor in Black Liquor Recovery Boilers
Patented SAFE-DRIVE retractor design prevents inadvertent errors during routine maintenance and can be conducted with a pressurized line
Long-term stability and the measurement principle with no moving parts provides years, even decades of accurate, continuous, fast and stable measurement
