  2. 2. Lignin Extraction from Black Liquor - Properties of the Liquors and Sulphur Content in the Lignin

    Author : Ali Seid Moosavifar; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat-treatment; lignin precipitation; boiling point elevation; lignin; alkalisation; biofuel; properties; viscosity; Black liquor; combustion of lignin; lignin modification; viscosity correlations.;

    Abstract : Kraft lignin isolated by precipitation can be considered as being a valuable renewable source of energy and material. Removing lignin from black liquor is also advantageous as it decreases the load on the recovery boiler, which is usually the limiting factor in the production of kraft pulp. READ MORE

  3. 3. Extraction of Lignin from Kraft Cooking Liquor by Ultrafiltration

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Ola Wallberg; Lund University.; Lunds universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignin; Chemical technology and engineering; cooking liquor; kraft black liquor; Kemiteknik och kemisk teknologi; Ultrafiltration;

    Abstract : Lignin is a potential biofuel which can be extracted from kraft cooking liquor. Lignin can also prove valuable as a speciality chemical. By extracting lignin potential economical revenue can be gained by pulp mills, as well as technical benefits such as easier delignification and bleaching. READ MORE
