Latest Patents

Rune L Pettersson holds a patent for a method aimed at reducing energy consumption at the refining of cellulose. The patent describes a technique that involves the addition of alkali to cellulose-containing material to neutralize acid groups bonded to the fiber wall. The process includes measuring the pH-value in the pulp suspension at the refiner outlet and adding alkali in a calculated amount based on the measured pH value. This method allows for neutralization without excess in the beating zone, with recommended amounts ranging from 0.05-9 kg/ton, preferably 0.5-5 kg/ton, and suitably 1-4 kg/ton, calculated as NaOH. This innovation is particularly relevant in the context of sustainable practices in the cellulose industry.
