    Sammanfattning : Sweden is one of the largest countries by area in Europe, and almost 70% of it is covered by forest. These abundant forest resources benefit the Swedish bioeconomy, but the pulp and paper industry is facing the challenge of a decrease in the demand for printing paper due to a significant shift to electronic media; therefore, it is a priority to use pulp to produce alternative value-added products, such as thermal insulating materials in buildings.

  7. 5. Vacuum Dewatering of Cellulosic Materials : New insights into transport phenomena in the papermaking process

    Författare :Björn Sjöstrand; Lars Nilsson; Christphe Barbier; Henrik Ullsten; Martin Hubbe; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum dewatering; numerical model; water removal; air penetration; papermaking; microfibrillated cellulose; dialcohol cellulose; strength additives; retention aids; drainage; water retention value; Chemical Engineering; Kemiteknik;

    Sammanfattning : Working towards sustainable development within the forest industry, the dewatering of pulp and paper must be fully understood along with the dewatering of other cellulose-based materials. Huge amounts of energy are used during paper manufacturing so there is a potential for making the processes more energy-efficient. LÄS MER
