  1. 1. Assessment of Raw Materials in Stainless Steelmaking-Their Energy Consumption and Greenhouse Gas Emission

    Författare :Wei Wenjing; Anders Tilliander; Peter Samuelsson; Pär Jönsson; Ye Guozhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static process model; mass and energy balance; molybdenum; nickel; phosphorus; stainless steel; life cycle assessment; GHG emission; energy consumption; statisk procesmodell; mass- och energibalans; molybden; nickel; fosfor; rostfritt stål; livscykelanalys; växthusgasutsläpp; energiförbrukning; Metallurgical process science; Metallurgisk processvetenskap;

    Sammanfattning : In stainless steelmaking, around 68% of the total greenhouse gas emissions come from the processing of raw materials. Thus, it is important for steelmakers to make efforts together with their raw material suppliers to implement low-carbon initiatives. To facilitate such initiatives, assessment of raw materials will provide guidance. LÄS MER

  3. 2. Renewables Based Polygeneration for Rural Development in Bangladesh

    Författare :MD. Ershad Ullah Khan; Andrew R. Martin; Semida Silveira; Peter Hagström; Jochen Bundschuh; Erik Ahlgren; Marcus Öhman; Monica Odlare; Lasse Aistrup Rosendahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digester; solar PV; polygeneration; cooking gas; gas engine; electricity; membrane distillation; arsenic safe water; Anaerobisk rötkammare; solceller; polygenerering; matlagningsgas; gasmotor; elektricitet; membrandestillering; arsenikfritt vatten; Energy Technology; Energiteknik;

    Sammanfattning : Despite the country's rural electrification programme, kerosene is the predominant source for lighting, and unsustainable and polluting woody biomass is virtually the only option available for cooking. The rural population also struggles with unsafe drinking water in terms of widespread arsenic contamination of well water. LÄS MER

  4. 3. Fire Dynamics in Multi-Room Compartment Fires

    Författare :Nils Johansson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire safety engineering; fire dynamics; multi-room compartment; numerical experiment; small-scale experiment; hot-gas-layer temperature; hot-gas-layer interface height; reproducibility;

    Sammanfattning : Fire dynamics in multi-room compartments are explored in this thesis and new methods to study conditions in rooms adjacent to the room of fire origin are presented. Simple and transparent engineering methods can create good possibilities for understanding different complex phenomena present in fire science. LÄS MER

  5. 4. Renewable Energy and Nutrient Valorization from Anaerobic Digestion : Resource-Efficient Solutions

    Författare :Sandra Carlos-Pinedo; Zhao Wang; Ola Eriksson; Shveta Soam; Henrik Wenzel; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid-state anaerobic digestion; methane yield; digestate; systems analysis; modelling; life cycle assessment; Torrötning; metanutbyte; biogödsel; systemanalys; modellering; livscykelanalys;

    Sammanfattning : This thesis presents a comprehensive analysis aimed at understanding process performance, methane yield, and key influencing factors within the context of solid-state anaerobic digestion (SS-AD). SS-AD is used to treat organic material with high solids content, which can be challenging to address by alternative methods. LÄS MER
