    Sammanfattning : Various process streams in the pulp and/or paper mill contain valuable substances which can be converted into new products, e.g. lignin and xylane. LÄS MER

  2. 2. Lignin Exraction from Black Liquor: Precipitation, filtration and washing

    Författare :Henrik Wallmo; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; Lignin; Filtration; Separation; Black liquor; Precipitation; Washing.; Absorption;

    Sammanfattning : Lignin extraction is a very interesting option for pulp mills today. Lignin is one major component, present as a dissolved organic compound, in black liquor, which is a by-product in the alkaline pulping of wood. After the digestion of wood chips, the black liquor is separated from the cellulose. LÄS MER

  3. 3. Precipitation and separation of lignin from kraft black liquor

    Författare :Fredrik Öhman; Chalmers University of Technology; []
    Nyckelord :pressing; filtration; washing; lignin; separation; precipitation; black liquor; extraction;

    Sammanfattning : The separation of lignin from black liquor is an attractive option to consider for pulp mills. In modern pulp mills, lignin extraction offers the opportunity of withdrawing an energy surplus in the form of a solid biofuel. LÄS MER
