  1. 1. Integrating Waste Heat from Hydrogen Production Into District Heating

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fawzi Kayali; [2023]
    Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

    Abstract : The steel industry plays a critical role in shaping the modern world, serving as a foundational pillar for infrastructure, construction, and manufacturing sectors. However, its rapid growth has sparked concerns regarding its environmental impact and sustainability. READ MORE

  5. 4. Integrating biomass gasification with electric arc furnace steel making

    University essay from KTH/Energiprocesser

    Author : Filippa Andersson; [2023]
    Keywords : Electric arc furnace; EAF off-gas; gasification; CCU; process integration; Ljusbågsugn avgasrök; ljusbågsugn; förgasning; kolavskiljning; process integration;

    Abstract : Utsläppen av växthusgaser ökar över hela världen och nya tekniker används för att minska utsläppen. 7% av utsläppen kommer från stålsektorn. 25% av världens stålproduktion görs via återvinningstekniken ljusbågsugn. Genom återvinningsprocessen släpps det ut 500kg CO2 per ton producerat flytande stål. READ MORE

  6. 5. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Elise Meurs; [2023]
    Keywords : Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

    Abstract : In this master thesis, the feasibility of Fenton-oxidation for the decolorization of reactive dyed cotton is investigated as a potentially environmental-friendly preparatory treatment for mechanical/chemical recycling. Raw, knitted cotton is dyed with a black and a blue dye, whereafter preliminary tests are performed to investigate the influence of increasing Fenton- solution concentrations and different iron-sources on the efficiency of the discoloration, without carrying out complete optimization of the process-parameters.
