Recent advances in the commercialization of NIR (near-infrar
ABSTRACT: Near-infrared (NIR) spectroscopy techniques have held the promise of a new generation of online and lab based process analyzers for the pulping and recovery areas for some years now. NIR technology has been shown to be a quite effective method for the analysis of white, green and black liquors by multiple investigators. NIR reflectance techniques have been shown to be effective in predicting yield and kappa number in pulp samples. Recently, commercial analyzers have been developed for green liquor analysis on the dissolving tank, white and green liquor analysis in the recaust area and black liquor analysis on batch and continuous digesters. These analyzers are currently running at different mill sites and are proving to be superior to current technology choices for these applications. A commercial online and lab based yield and kappa number analyzer are currently being developed based on NIR reflectance techniques. Results will be presented on the performance of these analyzers relating to accuracy, maintenance and total installed cost. Other potential NIR applications in the pulping and recovery area will also be addressed.
