  1. 1. Analysis and Performance Evaluation of a Three-phase Three-level Sparse Neutral Point Clamped Converter for Industrial Variable Speed Drives

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Pengpeng Sun; [2022]
    Nyckelord :Sparse Neutral Point Clamped Converter; Industrial Variable Speed Drives; Silicon IGBT; Calorimetric Measurement; Reverse Recovery Energy; Sparse Neutral Point Clamped Converter; Industriella Varvtalsstyrda Motordrifter; Silicon IGBT; Kalorimetrisk Mätning; Energi för Återhämtningsprocess;

    Sammanfattning : This thesis project focuses on the simulation, design, hardware realization, and performance evaluation of a Three-phase Three-level (3-L) Sparse Neutral Point Clamped Converter (SNPCC) for Industrial Variable Speed Drives (VSDs). The basic operating principle of the SNPCC is briefly described based on switching functions. LÄS MER

  3. 2. Integrating CO2 Utilisation and Biomass Gasification with Steel-making Electric Arc Furnaces (EAF)

    Master-uppsats, KTH/Energiprocesser

    Författare :Adel Mokhtari; [2022]
    Nyckelord :biomass gasification; carbon capture and utilization CCU ; process integration; electric arc furnace EAF ; EAF off-gas;

    Sammanfattning : Without a doubt, there is a consensus around the international community which suggests that our current way of life is unsustainable for a healthy planet, society and economy. One focal point that should be taken deeply into consideration is the steel industry as, globally, it accounts for 8% of global emissions. LÄS MER

  4. 3. Integrating membrane filtration forwater reuse in tissue mill

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Ehsan Moslehi; [2018]
    Nyckelord :Membrane separation; Paper industry; Paper mill effluent; Water reuse ; Reverse Osmosis;

    Sammanfattning : Water is an essential and indispensable component is the pulp- and paper production industry.The increase in energy costs, stricter environmental regulations and water resource shortageshave caused a reduction of the water footprint in the industry as well as an increase in waterrecycling and water circuit closure.

  5. 4. Energy and nutrient recovery from dairy manure : Process design and economic performance of a farm based system

    Master-uppsats, Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Tekniska högskolan

    Författare :Filip Celander; Johan Haglund; [2014]
    Nyckelord :Manure; cattle; fertiliser; nutrient recovery; renewable energy; manure separation; struvite; Stallgödsel; gödsel; gödselseparering; växtnäring; förnyelsebar energi; struvit;

    Sammanfattning : This thesis assessed the technical and economic premises for installing systems that process manure in order to recover nutrients and inherent energy. The main purpose of recovering nutrients was to extract phosphorus from the manure, so as to be able to distribute more of the manure on the farm without exceeding the phosphorus regulation. LÄS MER

  7. 5. Hydrogen as energy backup for the Hexicon : A case study on Malta

    Master-uppsats, KTH/Energiteknik

    Författare :Filipe Rebello de Andrade; [2013]
    Nyckelord :Desalination; Electrolysis; Fuel Cell; Hexicon; Hydrogen; Malta; Reverse Osmosis; Wind;

    Sammanfattning : The island of Malta is highly reliant on fossil fuels for its power (99%), and due to climate mitigation policies implemented by EU the Maltese government is required to have 10% of its power generation from renewables by 2020. To achieve these energy goals, the Maltese government has expressed interest in investing on a Hexicon platform to produce 9% of the Maltese energy demand. LÄS MER
