1. 1. Aluminum levels in the O-horizon of soils near Sundsvall, Sweden : Are levels of Al elevated due to smelter emission?

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Mattias Sundin; [2023]
   Nyckelord :Aluminium; Smelter emissions; O-horizon; Al concentration; Scots’ pine needles;

   Sammanfattning : Aluminum (Al) is a potentially toxic element for humans, animals, and plants. Al emitted from smelter plants is one source of Al that may be responsible for increased exposure to humans and the environment. LÄS MER

3. 2. Optimal joint operation of wind and hydropower

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Evangelos Bikis; [2022]
   Nyckelord :VRES integration; hydropower; wind power; business analytics; optimization; linear programming; clustering;

   Sammanfattning : Climate change drives policymakers to reduce emissions and enhance the integration of variable renewable energy sources (VRES) into the power system. Wind power is considered among the most beneficial VRES as it can generate cost-effectively carbon-free electricity but comes with inherent intermittency. LÄS MER

4. 3. Scrubbing of sulfur dioxide from secondary process gases in a copper smelter

   Master-uppsats, KTH/Kemiteknik

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

   Sammanfattning : 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. LÄS MER

5. 4. Characterisation of Used Lead-Acid Batteries for Feed Optimisation in Secondary Lead Production

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Linda Neiström; [2018]
   Nyckelord :Lead-acid battery; Boliden Bergsöe; Secondary lead production; Characterisation; Lead; Plastic separation;

   Sammanfattning : Used lead-acid batteries are the main raw material in secondary lead production. Technologicalprogress in the car industry, have raised concerns regarding the lead-acid battery’s leading positionas electrochemical storage system in the future. LÄS MER

7. 5. Energy Efficiency and Carbon Management in Mineral Processing Plants

   Master-uppsats, KTH/Kraft- och värmeteknologi

   Författare :Wilson Miti; [2014]
   Nyckelord :Energy Efficiency; Carbon Management; Carbon emissions trading; integrated energy and carbon management; energy-related emissions; mineral processing; carbon emissions in mineral processing; energy and carbon auditing; waste heat recovery in mineral processing; waste heat recovery for power generation; flue gas heat recovery;

   Sammanfattning : Copper processing plants involved in smelting, electro-refining and electro-winning are heat-intensive undertakings that provide extensive challenges for attainment of high energy efficiency. Literature has shown that most of these plants, especially smelters, operate at low overall energy efficiency due to the seemingly complex energy scenario where heat and electricity as forms of energy are treated distinctively from each other.
