  1. 6. Upgrading of Waste Tire Pyrolysis Oil

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Surapat Somsri; [2018]
    Nyckelord :;

    Sammanfattning : The annual increase in waste car tires in addition to the enormous amount at present poses a major waste management problem as well as an environmental hazard. However, pyrolysis is emerging as a solution for waste tire management and a viable technology for material recycling and energy recovery that produces high energy liquid and gas products as well as char.

  3. 7. Removal of hydrogen sulfide from an air stream using UV light

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Lorenza Gilardi; [2016]
    Nyckelord :VOC; sulfur removal; ozone; adsorbent bed;

    Sammanfattning : Volatile sulfur compounds are cause of concern because, when present in high concentrations, they constitute a danger for health because of their strong toxicity. Furthermore, for low concentrations, they are often a cause of complaint, because of their low odor threshold. LÄS MER

  4. 8. 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

  5. 9. Metal and metalloid sequestration in a constructed wetland system for treatment of landfill leachate during 2003-2012

    Magister-uppsats, Sektionen för ekonomi och teknik (SET)

    Författare :Tatsiana Bandaruk; [2013]
    Nyckelord :;

    Sammanfattning : Landfill leachate treatment can be expensive and energy consuming when carried out in wastewater treatment plants. However, there can be several possible solutions for reducing cost and energy requirements and one of them is on-site biological treatment of polluted landfill leachate in constructed wetland systems.

  7. 10. Split of sodium and sulfur in a Kraft mill and internal production of sulfuric acid and sodium hydroxide

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Helena Lundblad; [2012]
    Nyckelord :LignoBoost; electrodialysis; salt split; bipolar membrane; internal production;

    Sammanfattning : The removal of lignin in a Kraft pulp mill, with the aim to utilize the lignin as more value added green product than just firing lignin in black liquor, is possible with a LignoBoost plant. The LignoBoost plant uses sulfuric acid in the process and this results in an increased net input of sulfur to the pulp mills recovery cycle. LÄS MER
