  1. 1. On the local filtration properties during cake filtration: Studies on LignoBoost lignin and the influence of ionic strength

    Författare :Julie Durruty; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LignoBoost process; local filtration properties; dead-end filtration; softwood lignin; particles interactions; compressible filter cake; constitutive relationships;

    Sammanfattning : The Kraft pulping technology has been thoughtfullyinvestigated and developed over the pasthundred years and more; it is currently the mostcommonly-used method ofpulping in the world. Anew and promising opportunity for Kraft pulp millswould be to take a step towards becomingbiorefineries by implementing technologies ableto extract and convert the organic by-products,such as lignin, into a wide rangeof value-added products and chemicals.

    Sammanfattning : Kraft pulping technology is currently the most commonly-used method for producing paper pulp from wood. A new and promising opportunity for Kraft pulp mills is to take a step towards becoming biorefineries by implementing technologies able to extract and convert the organic by-products, such as lignin, into a wide range of value-added products and chemicals.
