Latest Patents

The available information identifies one patent associated with Van Fleet: Method for Distributing Chemicals in Delignification Stages of Pulp Bleaching Process. The invention describes methods, systems, and apparatus for determining and applying oxidizing-agent dosages during pulp delignification.

The method uses the incoming kappa value of unbleached pulp and the target kappa value for bleached pulp. A model derives a sequence kappa factor and then calculates a total equivalent chlorine factor. It simulates scenarios with different oxidizing-agent dosage targets, scores each scenario according to total chemical consumption, and selects the scenario with the lowest score. The selected dosage targets are then applied during the bleaching cycle. Van Fleet is associated with 1 patent.
