Cost – Quality – Innovation
Nouryon understands that to remain competitive in
the global market our customers must continuously
improve their process and lower their operating
costs while still maintaining consistent pulp quality.
We know that bleaching chemicals represent asignificant proportion of the variable cost toproduce pulp - up to 25%. It is important tomaximize the efficiency of this process, which canalso be affected by wood quality, cooking andbrownstock washing.
Optimization
Our team has access to a variety of optimizationtools. With a laboratory bleaching study we cansimulate almost any stage or sequence. Whether it
is optimizing a specific parameter or balancing anentire sequence, we have this capability.

Statistical design is used to get the most out ofthe data generated. These studies are great foranswering “what if?” questions. The data
generated can be used to create bleach plantmodels for further exploring operational changes
including balancing wood, energy and chemicalcosts, determining brightness ceiling oranswering “cost of brightness” questions.
Benchmark studies are conducted at the millsite. Our experts analyze detailed operating
data to come up with recommendations; often
identifying actions that result in significant
reoccurring annual savings.
We can also evaluate and make observations on
bleach plant washers. This kind of survey can leadto recommendations for improving carryover,chemical usage, and quality.
