  1. 1. Techno-economic Optimization for Large-Scale Power-to-methane Systems : Techno-economic modeling, design and optimization of a large scale 2.0 TWh/y solar-to-methane plant concept in Australia

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Antoine Perdriel; [2021]
    Nyckelord :;

    Sammanfattning : Industrialized societies are built on the limited, extraordinary dense form of energy that are the fossil fuels: coal, oil, and gas, that became the core driver of the economic growth since the industrial revolution. While most emission pathways highlight the necessity to reach net zero emissions before 2050, there are numerous challenges to the displacement of fossil fuels by renewable energy systems (local conditions, intermittency, raw materials) and applications to the most polluting sectors such as transportation remain a major challenge.

    Nyckelord :energy efficiency; petroleum industry; upstream; associated petroleum; energieffektivitet; petroleumindustri; uppströms; associerad petroleumgaser; avlägsna oljefält; gas-till-olja-förhållande; fackling;

    Sammanfattning :  In this thesis the analysis of the oil and gas industry was carried out in terms of possibilities of improving its energy efficiency and carbon emission reduction potential. The largest potential is concentrated in pipeline transportation and petroleum extraction (upstream) sectors. LÄS MER

  4. 3. Heated Dipstick

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Sebastian Wattle Björk; Omar Ali; [2017]
    Nyckelord :Dipstick; Heat transfer; Thermodynamics; engine oil; mineral oil; synthetic oil.; Oljesticka; värmeöverföring; termodynamik; motorolja; Syntetisk olja;

    Sammanfattning : Starting an engine in low temperatures creates unnecessary wear on components due to the insufficient lubrication of cold engine oil. A cold engine produces more emissions and consumes more fuel. Not all cars are equipped with engine heaters and installing an aftermarket heater is both expensive and time consuming. LÄS MER

  5. 4. The Sustainability related opportunities and challenges with various transformer insulation fluids and business case on re-refining

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Ibrahim Gharib Ali Jalal; Abdulbasit Abdulaziz Ali; [2017]
    Nyckelord :Transformer oils; LCA; Re-refining; Business case; Sustainability;

    Sammanfattning : Transformers are electrical devices used in practice to increase or decrease voltages. Transformers are of various sizes and used mainly in power distribution. To provide cooling and insulation, transformer oils are used together with cellulose that acts as a solid insulation. LÄS MER
