Compression refining: the future of refining? Application to Nordic bleached softwood kraft pulp, TAPPI Journal August 2024
ABSTRACT: A new compression refining technology based on the kneading of high consistency pulp has been selected and tested in various conditions with a model Nordic bleached softwood kraft (NBSK) pulp. The method uses a kneader mixer referred to as the ultra continuous mixer (UCM) to condition the pulp. Its performance levels were also compared with those obtained with traditional low consistency (LC) refining of the same pulp.Compression refining of the NBSK pulp with the UCM led to a much better °SR/strength compromise than conventional LC refining. High strength properties can also be achieved by compression refining, in a range similar to/or better than LC refining. The higher the strength required, the greater the advantages of this technology: for a given strength, a difference of up to 10°SR can be obtained as compared to LC refined pulp. Moreover, a higher tear index can be obtained with compression refining, since fiber cutting is greatly reduced.The lower °SR is due to the release of fewer cellulosic fines, which also results in the manufacturing of new papers combining a high strength and a high permeability that cannot be obtained with traditional LC refining. Indeed, with LC refining, a high strength is generally associated with a low permeability. Upscaling this technology seems to be possible since large production devices are already on the market for applications other than paper/pulp. With this new pulp behavior, papermakers will have to learn to think differently, as paper strength and °SR can now be decorrelated.
