SPK-5500: Fiber kappa

A kappa number analyzer mounted directly to the pulp processing line

BTG’s, Single Point Kappa Analyzer, SPK-5500, is an in-line kappa analyzer which measures the lignin content of pulp fibers. Optionally it can also measure hexenuronic acid (HexA). The analyzer is mounted directly to the pulp processing pipeline and contains all unit operations of the traditional multi point kappa analyzer. Thus, there is no need for the remote pulp sampler, associated water valves and transport lines from the sampler to the kappa analyzer. The SPK handles all operations in one unit – pulp sampling, screening, washing, and optical kappa number measurement.

Because the SPK is dedicated to one position, it supplies kappa results at a much faster rate, 10 – 12 kappa results per hour, compared to the traditional multi point kappa analyzer’s typical 2 – 3 results per hour. This will significantly improve the accuracy of the signal applied for the process control, subsequently enhancing the performance of the production process.
