  1. 21. Influence of mixing and heat transfer in process scale-up

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

    Författare :Paula Martín Díaz; [2022]
    Nyckelord :Scale-up; mixing; heat transfer; computational fluid dynamics; process simulation;

    Sammanfattning : Process scale-up studies are, generally, non-linear. This basically means that it is not possible to take a chemical process in the laboratory and bring it to a pilot or production plant by simply increasing the quantities of chemicals and the equipment size proportionally.

  3. 22. Development of a Flow Dependent Chemical Reaction Model using CFD

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

    Författare :Martin Östman; [2022]
    Nyckelord :CFD; Fluid mechanics; Rotating Bed Reactor; Ansys Fluent; Decolorization; CFD; Strömningsmekanik; Roterande Bäddreaktor; Ansys Fluent; Avfärgningsprocess;

    Sammanfattning : In many technical applications chemical reactions are used. One of these is a so called decolorization, in which an ion exchange resin is used to remove a dye from water. To apply this decolorization technique a Rotating Bed Reactor, or RBR for short, can be used. It is filled with the ion exchange resin and spun inside the water. LÄS MER

  4. 23. Experimental Study of Internal Injector Deposits In Internal Combustion Engines Using Renewable Fuels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Patrick Kiprotich Korir; [2021]
    Nyckelord :;

    Sammanfattning : The  strive  to  minimize  emissions  in  the  automotive  industry  keeps gaining momentum. Continuous improvement of engine designs and development of more efficient  fuel  systems  in  diesel  vehicles  is  a  solution to  be  applauded. LÄS MER

  5. 24. Techno-economic Pricing model for Carbon Neutral Fuels as Seasonal Energy Storage

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

    Författare :Ananya Saraf; [2021]
    Nyckelord :Hydrogen; seasonal storage; geological storage; carbon-neutral fuels; Vätgas; säsongslagring; geologisk lagring; koldioxidneutrala bränslen;

    Sammanfattning : Green hydrogen produced through electrolysis of excess renewable energy is a promising seasonal energy storage solution with the potential to decarbonize the energy sector. However, it has physical properties that make it difficult to store and transport on a large scale for grid scale storage applications. LÄS MER

  7. 25. Positioning Electric Field Sensors in the Marine Environment Using Passage Data

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Maria Langkilde; [2021]
    Nyckelord :electromagnetism; electric field sensors; sensor; marine environment; elektromagnetism; elektriska fältsensorer; sensor; marin miljö;

    Sammanfattning : When underwater sensors are being deployed there is always some uncertainty about the actual position of the sensors. The most common way of determine the sensors position is the use of hydro-acoustic methods. However, for electric field sensors the most favourable would be to use the sensor system itself. LÄS MER
