    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; process modeling; phosphorous capacity; penetration depth; slag foaming; mixing time; inclusion removal;

    Sammanfattning : The present thesis deals with the development of a new type of dynamic model for metallurgical reactors. It also covers some of the theoretical aspects of steelmaking that is necessary to include in such an application. The thesis consists of modeling work, high temperature experiments and cold model experiments. LÄS MER

  5. 14. Selective Separation Of Wood Components In Internal Process Waters Originating From Mechanical Pulping

    Författare :Dariusz Zasadowski; Magnus Norgren; Bjarne Holmbom; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flotation; foaming agents; chelating surfactant; TMP process water; pitch control; internal cleaning stage; hemicellulose recovery; anti‐solvents; solvents; precipitation;

    Sammanfattning : Dissolved and Colloidal substances (DSC) and metals are released from woodduring thermomechanical pulp (TMP) production. These components have atendency to accumulate in process waters, as the water circulation systems inintegrated paper mills are closed. LÄS MER

  7. 15. REMOVAL OF LIPOPHILIC EXTRACTIVES AND MANGANESE IONS FROM SPRUCE TMP WATER BY FLOTATION

    Författare :Dariusz Zasadowski; Magnus Norgren; Anna Sundberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flotation; Foaming agents; Chelating surfactant; TMP process water; Pitch control; Internal cleaning stage;

    Sammanfattning : Dissolved and Colloidal substances (DisCo) and metals are released from wood during thermomechanical pulp (TMP) production. The mechanical treatment causes that these components have a tendency to accumulate in process waters, as the water circulation systems in integrated paper mills are being closed. LÄS MER
