  3. 3. Neutralization of acidic wastewaters with the use of landfilled Electric Arc Furnace (EAF) high-alloyed stainless-steel slag : An upscale trial of the NEUTRALSYRA project

    University essay from KTH/Materialvetenskap

    Author : Rahul Puthucode; [2019]
    Keywords : Landfilled High-alloyed Electric Arc Furnace EAF slag; Slag neutralization potential; Slag recycling;

    Abstract : The landfilling of slag obtained from the high alloyed Electric Arc Furnace (EAF) steel making process, constitutes an environmental treat for society as well as an economical problem for the companies producing it, due to the costs related to waste management practices. Conventional methods of slag recycling are abundantly used among the steelmaking business, but due to their particular physical properties, high- alloyed EAF slags cannot be properly valorized.

  4. 4. Production optimization for district heating : Short-term planning of district heating grid in Gävle, Sweden

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Nicolas Lindgren; Karl Brogren; [2019]
    Keywords : Short-term planning; Optimization; District heating; Linear programming; Mixed integer non-linear programming; Branch and bound; Heat storage; MATLAB; TOMLAB;

    Abstract : Energy systems with a high portion of renewable energy from wind and solar power can suffer from fluctuations in production due to weak winds or cloudy weather, which may affect the electricity price. When producing heat and power in a combined heat and power plant, an additional heat storage tank can be used to store the heat surplus which is obtained when the power production is high, and the heat demand is low.

  5. 5. Influence of Nucleation Techniques on the Degree of Supercooling and Duration of Crystallization for Sugar Alcohol as Phase Change Material : Investigation on erythritol-based additiveenhanced Composites

    University essay from KTH/Energiteknik; KTH/Energiteknik

    Author : JiaCheng Lin; HaoRan Teng; [2019]
    Keywords : Phase Change Material; Latent Thermal Energy Storage; Temperature-history; Sugar Alcohols; Supercooling; Duration of crystallization; Crystallization; Solidification; Fasändringsmaterial; Latent Termisk Energilagring; T-history; Sockeralkoholer; Underkylning; Varaktighet av kristallisering; Kristallisering; Stelning;

    Abstract : Utilizing Phase Change Materials (PCM) for Latent Thermal Energy Storage (LTES) applications have previously been extensively researched as a measure to reduce greenhouse gas emissions from energy consumption. In order to make use of the waste heat from industrial processes for LTES purposes, a new demand emerged for PCMs capable of phase change in mid-temperature ranges of 100 °C - 200 °C. READ MORE
