Short oxygen delignification method |
| abstract |
A short oxygen delignification method employs a mixing assembly including a mixing chamber having an interior wall which is generally symmetrical about a central longitudinal axis. At least one inlet is used to introduce paper pulp, a basic compound, optional steam and an oxygen-containing gas into the mixing chamber. At least one axial baffle is connected to and extends along the interior wall. At least one transverse baffle is connected to and extends from the interior wall transverse to the axis. A rotatable agitator includes at least one agitator baffle extending transverse to the axis at a location in alignment with a respective transverse baffle. This forms at least one gap between the at least one agitator baffle and the at least one respective transverse baffle. The paper pulp fluid is forced to travel through the at least one gap. A short delignification reaction occurs inside the mixing chamber. Delignified paper pulp fluid leaves the mixing chamber through at least one outlet of the mixing chamber. |
