N and Fe codoped carbon dots (N, Fe-CDs) were fabricated from citric acid, L-glutamic acid
and ferric chloride via a hydrothermal method for the photocatalytic removal of S2− from kraft …

Efficiency decline in the recovery cycle of Kraft pulp and paper mills can create dynamic
conditions that lead to evaporator scaling and poor combustion properties at the recovery …

Brownstock washing, a critical process in cleansing kraft pulp, removes dissolved lignin
residues from the pulp after it has passed through the cooking digester. It plays a significant …

In both pulping and bleaching processes, lignin in the pulp fiber is degraded into smaller
molecules that need to be rinsed away. However, despite the installation of automatic …

In previous studies, generalized steady-state models were proposed to approximate the
chlorine dioxide demand needed for the delignification of softwood and hardwood pulps …

The efficiency of the kraft recovery plant, bleaching process, and paper machine are affected
when black liquor carryover from the brownstock washers is not controlled well. Measuring …

Cellulose acetate pulp was produced from viscose-grade, unbleached and bleached
