  1. 11. Scrubbing of sulfur dioxide from secondary process gases in a copper smelter

    University essay from KTH/Kemiteknik

    Author : Obiora Okolo; [2021]
    Keywords : sulfur dioxide; scrubbing; smelter; process industry; flue gas desulfurization; svaveldioxid; skrubbning; smältverk; processindustri; rökgasavsvavling;

    Abstract : Processindustrin är den största källan för utsläpp av svaveldioxid (SO2) i Sverige, vilket även inkluderar icke­järnmetallindustrin. Kopparsmältverket Boliden Rönnskär har ett miljötillstånd som tillåter SO2­-utsläpp på maximalt 3500 ton/år, en gräns som Rönnskär har legat nära under de senaste åren. READ MORE

  3. 12. Exploring Managerial Challenges Emerging from Procurement of Mineral Concentrates : Case study on Boliden

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : SANJIN PEPIC; BABACK ZARIF; [2021]
    Keywords : Mining; refining; procurement; copper; complex concentrate; challenges; Gruvindustrin; raffinering; inköp; koppar; komplex koncentrat; utmaningar;

    Abstract : Procurement of copper concentrate is becoming increasingly more challenging as the general quality of concentrates are decreasing. Concentrates are now coming with higher shares of impurities and secondary materials, which makes them harder to process. READ MORE

  4. 13. Biochar-based thin-layer capping of contaminated sediment in Burefjärden, northern Sweden : Assessment of biochar mixed into four structural materials for preventing release of trace elements from sediment to water

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Nathalie Pantzare; [2021]
    Keywords : biochar; contaminated sediment; remediation; thin-layer capping;

    Abstract : Coastal areas around the world have been recognized as largely impacted by anthropogenic activities resulting in pollution of marine sediments. In Sweden, surveys conducted along the coastline of the Bothnian Bay have identified a total area of about 29 km2 as fiber rich sediments. READ MORE

  5. 14. Experimental Investigation of the Thermal Performance and Pressure Loss in Additively Manufactured mini-channels

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Anna Nyhlen; [2021]
    Keywords : ;

    Abstract : Industrial gas turbines reach temperatures of 1500-2000K at high rotational velocities which means that much effort is spent on the design of an efficient cooling system. With the recent advances of the additive manufacturing (AM) industry, new design opportunities have open up for many industries and applications, including the design of cooling systems. READ MORE

  6. 15. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Brianna Kilberg; [2020]
    Keywords : Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

    Abstract : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. READ MORE
