A new analyzer for high-yield and brown pulp
The new Brown Stock Analyzer (photo) was developed to complement this company’s online pulp-quality analyzer family. The analyzer provides high analysis frequency for digester and brown-stock washing control in kraft pulping. It is said to be the most robust Kappa measurement available for high yield and brown pulp, designed to measure the coarsest pulp starting from the cooking blow line. It is the only analyzer in the market with dual sampling points for blow line Kappa, before and after refining. Accurate and frequent Kappa profile ensures superior process control and enables the mill to optimize cooking parameters, resulting in better yield and pulp quality, the company says. The analyzer uses a well-proven sampling technology to extract a pulp sample and transport it to the analysis unit, where the dissolved lignin is thoroughly washed, and pulp Kappa number analyzed by an advanced optical measurement technology. The Kappa measurement range is 9–120. — Valmet Oyj, Espoo, Finland
