  1. 6. Optimering av kalkcykeln på Iggesunds bruk med avseende på specifik energianvändning

    University essay from SLU/Dept. of Energy and Technology

    Author : David Olsson; [2020]
    Keywords : energieffektivisering; mesaugn; elfilterstoft; sulfatmassa; kartongbruk;

    Abstract : Iggesund Mill is an integrated pulp and paperboard mill that makes kraft pulp and solid bleached board. In the pulp process, white liquor is used to make pulp. The white liquor is recovered in the recovery process. READ MORE

  3. 7. Development of magnetic lignin nanoparticles from low-molecular-weight eucalyptus and spruce lignin fractions

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Anna Wessén; Eliot Diklev; Lejla Al-Tamimi; [2020]
    Keywords : Magnetic nanoparticles; Hardwood; Softwood; Self-assembly; Lignin;

    Abstract : Lignin is one of the most common biopolymers in the world. Together with cellulose andhemicellulose it constitutes the fibers in the wood. It has a high molecular weight due to its complexstructure consisting of crossed-linked phenolic monomers and is concatenated with different types ofcarbon and ether bonds. READ MORE

  4. 8. The impact of the pulping process on the properties of lignin nanoparticles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kristoffer Guthenberg; [2020]
    Keywords : Lignin; Nano; Nanoparticles; Extraction; Kraft; Organosolv; Softwood; Properties;

    Abstract : Lignin valorization is a key component of the total utilization of biomass in the biorefinery industry. Lignin has seen some use in several different applications, but a breakthrough is still yet to happen, and there is still a need to find more areas where lignin can be used as an alternative feedstock or as the main component.

  5. 9. Studies of the Impregnation Stagein Kraft Pulping of Hardwood

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Jonas Garemark; [2018]
    Keywords : ;

    Abstract : In kraft pulping, one of the main issues is the extensive wood losses. With increasing prices ofwoody biomass an incentive towards minimizing the wood losses exists. Amongst the variousprocess steps, the impregnation of wood chips has shown to enhance the cooking by providinga homogeneous distribution of chemicals inside the chips. READ MORE

  6. 10. Pulp mill heat and mass balance model : Exploring the benefits and possibilities of process modelling as an applied method in a case study

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Simon Mählkvist; Netzell Pontus; [2018]
    Keywords : Energy balance model; kraft pulping; component based modeling; heat and mass balance model; digester model; impregnation vessel model; chip steaming and feeding model;

    Abstract : This thesis focused on the modelling of a pulping process. The purpose was to see if an accurate model can be crated based on relatively simple premises and if the errors can be identified or analysed. To realise this, the authors conducted a literature study to identify the current state of the art regarding the chemical pulping process. READ MORE
