  • Pulp and Paper Industry
    The pulp and paper industry uses various chemicals to process pulp, both directly and indirectly. Hydrogen sulfide is created as a by-product of the digester process. Chlorine and chlorine dioxide are used during the bleaching process, while combustible gas detection is used during the drying
  • New analysis methods for digester management
    control must pay attention to this variation, otherwise it will have significant effects on cooking conditions and pulp quality. The alkali analyzer was installed to a continuous digester to measure incoming white liquor quality. This mill uses a two-vessel vapor/liquid phase digester with a daily
