FITNIR Kraft Pulping Operation Process Analyzer:
Digester Process Optimization with Online FT-NIR Liquor Composition Measurements
The FITNIR digester analyzer provides white and black liquor compositions. For black liquor, REA is measured as well as organic and inorganic content, which is not offered by any other techniques. Complete liquor compositions can be measured using FITNIR’s technology.

Optimization of Digester Operations
The primary advantage of applying the FITNIR digester analyzer is its ability to provide WL EA and sulphidity as well as BL REA at the various zones, reliably and accurately. Control strategy based on reliable data can significantly reduce kappa variation, overcooking and rejects while increasing pulp quality.

Reducing kappa variability could also have a significant reduction in bleaching costs. As a result, improvement in yield is possible with FITNIR’s digester analyzer.

Benefits of FITNIR digester analyzer-based control
> Improved digester control
> Reduced bleaching cost
> Reduced off-grade pulp
> Reduced white liquor consumption
> Reduced lab tests
