Abstract: A method of making pulp adapted to be used in forming corrugating medium is disclosed. The method comprises cooking woodchips in a first liquor in the absence of an alkali addition. The method further comprises mechanically fiberizing the woodchips to form a pulp. The method further comprises separating hydrolyzate from the pulp. The method further comprises treating the pulp with a second liquor, the second liquor including at least one alkali. The method further comprises refining the pulp.

Abstract: A method for removing residual oxygen from an aqueous slurry of pulp that has been oxygen-bleached is disclosed. The slurry, usually containing no more than 3 weight percent fiber, is agitated by a radial-flow impeller, which imparts a substantially radial flow to the slurry. If the residual oxygen is not removed, it may degas at an inopportune moment during later processing (for example, washing) and carry some of the wood fibers to the surface of the slurry, thereby forming a foamy mat, which hinders further processing.
