    摘要: Methods for mixing a treatment agent with a pulp suspension are disclosed including supplying the pulp suspension to a mixing chamber, moving the pulp suspension through a mixing zone with the mixing chamber, supplying the treatment agent to the moving pulp suspension across the entire width of the mixing chamber prior to the mixing zone, and in which the height of the mixing zone is sufficiently small such that the pulp suspension and the treatment agent are subjected to kneading within the mixing zone in order to repeatedly stretch and compress fiber flocks in the pulp suspension. Apparatus for mixing the treatment agent with the pulp suspension are also disclosed.

    摘要: Methods for oxygen delignification of chemical pulps are disclosed including contacting the chemical pulp with oxygen first in an upstream reactor vessel and then in a downstream reactor vessel. The upstream reactor vessel is maintained at pressures of greater than about 3 bar, and the downstream reactor vessel is maintained at temperatures of between about 90 and 120° C. and corresponding predetermined pressures. Heating of the partially delignified chemical pulp between the upstream and downstream reactors is accomplished by contacting the partially delignified chemical pulp with low pressure steam.
