Digester

Business Problem

In cooking, stable quality (consistency and kappa) from the digester are key to enable more cost-effective operations at subsequent processing stages. Benefits include lower use of energy, chemicals and fresh water, as well as reductions in unplanned downtime and maintenance costs.

Challenge

Variation in feedstock properties, such as size and lignin content, make steady-state operation difficult to attain. Additionally, not all key variables are measured or directly manipulable.

SentianController solution

SentianController’s variation reduction technology can continuously predict key quality measures at the blow line, enabling optimized control of key variables such as temperature and alkali dosage.
