  1. 6. Concept development to extract sodium sulfate from an aqueous solution

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :André Selander; [2021]
    Nyckelord :biorefinery; aqueous solution; sodium sulfate; crystallisation; crystallization; kraft process;

    Sammanfattning : Now when the interest is increasing to reach a sustainable infrastructure, one possibility SCA is experimenting with is the possibility to produce renewable hydrocarbons from black liquor which can be extracted from a Kraft process. However, when extracting the black liquor, a lot of sodium-based compounds are removed from the recovery process and when hydrocarbons are produced in SCA’s biorefinery, these compounds are caught in an aqueous solution.

  3. 7. The carbon footprint caused by the oversizing of building service systems : A case study of an NHS Hospital

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Maria Hein; [2020]
    Nyckelord :Design; dimensioning; heating; cooling; boiler; chiller; pump; energy performance; environmental impact; mitigation strategy;

    Sammanfattning : Energy usage in buildings is a main contributor to CO2 emissions and in order for the EU to reach the 2050 goal of carbon-neutrality, there is a great need to improve the energy efficiency in buildings, particularly commercial buildings that often are substantially overdesigned. Excess margins in the design process of building services result in an oversizing of these systems which has great environmental impacts, divided up as the operational and embodied carbon footprints.

  4. 8. Design and Development of an Experimental Test Rig for Heat Sinks

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Gabriel Kaduvinal Abraham; [2020]
    Nyckelord :Cooling; Experimental Setup; Flow rate; Heat sink; Plumbing; Sensors; Thermal Efficiency; Kylning; experimentell installation; flödeshastighet; kylfläns; VVS; sensorer; värmeeffektivitet;

    Sammanfattning : Heat sinks are used mainly to take away the excessive heat which are produced in a component. This transfer of heat enables a smooth operation of the system with the heat generating component. The efficiency of heat sink is often dependent on the amount of heat it can take away within the smallest duration of time. LÄS MER

  5. 9. Utveckling av oljetestrigg för Compactmotorer

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Jakob Friman; [2019]
    Nyckelord :Hydraulik; Tribologi;

    Sammanfattning : Bosch Rexroth i Mellansel, Sverige levererar kompletta hydraulsystem för applikationer som kräver lågt varvtal och högt vridmoment. Hydraulmotorn, som är en radialkolvsmotor med kamring, utvecklas och tillverkas i fabriken i Mellansel där det även finns ett stort hydraullaboratorium för att kunna testa motorerna. LÄS MER

  7. 10. ADAPTION OF A HEATSINK TO ADDITIVE MANUFACTURING. : INCLUDING A GUIDE TO INDUSTRIAL STARTUP OF AM.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Richard Ingman; [2019]
    Nyckelord :Additive Manufacturing; AM; 3D printing; Industrialization; Heatsink.; Additiv Tillverkning; 3D-printning; Industrialisering; Kylare.;

    Sammanfattning : This thesis is an investigation of the current status of additive manufacturing (AM) regarding different technologies, the level of implementation in industry and the future obstacles for further implementation. As a secondary objective, an existing heatsink for electronic equipment was redesigned, adapted to and improved using the design advantages of AM, and was later manufactured through 3D-printing in aluminium (AlSi10Mg).
