ASD Technical Presentation:

Rapid at-line and on-line determination of pulp mill process variables

Presenter: Brian Curtiss

Near Infrared (NIR) reflectance spectroscopy is being used increasingly as a technique to provide information necessary to optimize the pulp making process. Material properties of interest are related to measured reflectance using statistical techniques. The advantage of the technique is the speed of measurement and the ability to perform non-contact
measurements. Analyzer systems have been developed for both at-line and over-theconveyor on-line installations. The development of an NIR calibration involves five step:

  1. a set of samples with known physical or chemical properties is assembled;
  2. the NIR reflectance spectra of this sample set are collected;
  3. the spectra and the properties of interest are correlated using one of several multivariate techniques;
  4. the reliability of each calibration is validated;
  5. the validated calibrations are used to predict properties of interest for unknown samples. Examples presented include: at-line analysis of pulp kappa and brightness; on-line analysis of lime mud moisture and color; and, on-line analysis of wood chip moisture and blue-stain.
