  5. 15. Sustainable Aluminum and Iron Production

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Reza Beheshti; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Optimization; Black Dross; Salt removal; Steel flux agent; Waste processing; Greenhouse gases; Direct reduction; COMSOL Multiphysics®; Kemi; Chemistry;

    Sammanfattning : Aluminium recycling requires 95% less energy than primary production with no loss of quality. The Black Dross (BD) produced during secondary aluminium production contains high amounts of water-soluble compounds, therefore it is considered as a toxic waste. LÄS MER
