Stabilize and optimize bleach operations in real time with OPT800 Bleach. The Advanced Process Control solution tightly controls Kappa reduction to preserve pulp quality, while also minimizing chemical usage and reducing formation of chloro-lignin compounds. The end result means you can consistently reach your brightness targets.
Efficient running of pulp bleaching stages is often challenging for operators, who must control numerous reactions to consistently hit final brightness targets, while also preserving the fiber strength (pulp viscosity). It’s a delicate balancing act that is influenced by many dynamic variables, both in the bleaching stages and also by the preceding digester and oxygen operations. Getting stable runs can require frequent operator intervention.
Opt800 Bleach tightly controls Kappa to preserve pulp quality during the bleaching phase. In the subsequent stages, brightness and chemical residuals are tightly controlled. Mills can better meet their brightness targets—with 30-50% lower brightness variation and 3-10% lower chemical costs.
