Using white liquor as the alkali source in oxygen delignification
TAPPI Journal, 2016This paper considers the potential impact on oxygen delignification stage performance when unoxidized white liquor and partially oxidized white liquor containing thiosulfate, or (OWL[T]), are used as the alkali source. A literature review was conducted to estimate the oxygen consumption of the pulp, the raw black liquor carryover, and the sulfur ...

Gas flow hydrodynamics in an oxygen delignification retention tower
2009Gas flow hydrodynamics were characterized as a function of pulp suspension concentration in a laboratory-scale residence tower. Three kraft pulps were studied: never-dried brown stock (kappa 33), a fully bleached kraft pulp (88-89% brightness) that never had been dried, and a dried and reslurried fully bleached kraft pulp (88-89% brightness).
