Model-based kraft cooking optimisation

Nordic Pulp & Paper Research Journal, 1997
A recently proposed model for kraft delignification kinetics is used to generate optimum operating conditions for the production of kraft pulp. In contrast to previous models, the optimal profiles for temperature, [OH] and [HS] support the current operating practice in mill digesters. The optimisation results suggest coupling as high a [HS] as possible

Ultrafiltration of kraft cooking liquors from a continuous cooking process

Desalination, 2005
Two cooking liquors and a black liquor were fractionated by ultrafiltration. The liquors were withdrawn from different stages in a kraft pulp mill employing continuous digestion. The ultrafiltration was performed at 90 degrees C with two ceramic membranes with cut-offs of 5 kDa and 15 kDa.

A survey of kraft cooking control models

IFAC Proceedings Volumes, 1980
Abstract A survey of general kraft cooking control principles, especially of control models has been done. Basic assumptions, model principles, major and auxiliary variables used as well as updating of models have been considered. A variety of theoretical and experimental models published are described in the text provided with the control ...
