  1. 6. Handlingsplan för ägare av transformatorer med korrosiv olja

    M1-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Stephan Weidemann; [2016]
    Nyckelord :DBDS; kopparsulfid; dibensyl disulfid;

    Sammanfattning : Sedan början av 2000-talet har ett stort antal transformatorer havererat av en initialt, okänd anledning. Problemet visade sig vara att en antioxidationstillsats i oljan, dibensyl disulfid (DBDS), reagerat med kopparen i lindningarna och vilket gett upphov till avlagringar på isolationspapperet i form av kopparsulfid.

  3. 7. A desulphurization study of hot metal at SSAB Europe Luleå with added bottom stirring of nitrogen gas

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Mattias Edvartsen; [2015]
    Nyckelord :desulphurization; desulfurizing; removal of sulfur; steel; bottom stirring.;

    Sammanfattning : This bachelor degree project is about determining the impact that additional bottom stirring may have on the desulphurization process at SSAB Luleå. During one week of field work steel samples were collected from 39 different heats. LÄS MER

  4. 8. Air injection techniques for seawater flue gas desulphurization (SWFGD) aeration system.

    Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

    Författare :LINBO HAN; [2012]
    Nyckelord :Seawater flue gas desulphurization SWFGD ; Aeration; oxygen transfer; Carbon dioxide stripping;

    Sammanfattning : Seawater flue gas desulphurization (SWFGD) is a reliable and efficient process to re-move sulfur dioxide in flue gases in power plants and industries. The characteristics and applications of seawater treatment plant of three SWFGD process are described firstly. LÄS MER

  5. 9. A pre-study of Hot Metal Desulphurization

    Master-uppsats, KTH/Materialvetenskap

    Författare :Annika Fang Yang; [2012]
    Nyckelord :Desulphurization; hot metal; SEM analysis;

    Sammanfattning : In this thesis work, some basic concepts about desulphurizationof hot metal have been done based on a literature study. Two experimentaltrials have also been carried out to study the slags: one consider as areference and in the other trial, the amount of calcium carbide was reduced by150 kg. The average carbide efficiency has been improved from 21. LÄS MER
