  1. 1. Hydrothermally carbonized wood as a component in biobased material for 3D-printing

    L2-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Matilda Hendeberg; [2020]
    Nyckelord :Hydrothermal carbonization; 3D printing; biobased materials; biodegradable;

    Sammanfattning : Consumers put higher demands on low environmental impact from the products they use, and the materials they consist of. As a result, more research is being made on finding environmentally friendly production techniques and materials. Hydrothermal carbonization (HTC) is a relatively environmentally friendly method that has been used in this study. LÄS MER

  2. 2. High Resolution 3D Printing with Cellulose Acetate

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Nils Heyman; [2020]
    Nyckelord :3D printing; cellulose acetate;

    Sammanfattning : In this project, an additive manufacturing technique called Direct Ink Writing has been used to 3D print structures from polymer solutions containing cellulose acetate. Cellulose acetate is a synthetic compound derived from plants. The intended application involves protein separation filters for medical purposes. LÄS MER

  3. 3. Theoretical and Experimental Characterizationof a Soft Polymer Heat Exchanger forWastewater Heat Recovery

    Master-uppsats, KTH/Energiteknik

    Författare :Sixiang Lyu; [2020]
    Nyckelord :polymer heat exchanger; wastewater; heat recovery; heat transfer enhancement; oscillation i; polymervärmeväxlare; avloppsvatten; värmeåtervinning; förbättring av värmeöverföring; svängning;

    Sammanfattning : Wastewater released from showers, sinks, and washers contains a considerable amount of wasteheat that can be recovered by using a heat exchanger. Conventional metal heat exchangers for wastewater heat recovery have common problems of corrosion, fouling and clogging, which makes it necessary to develop a new type of heat exchanger for such low-grade thermalenergy recovery applications.

  4. 4. Worst Credible Process Fire: Experiences from the Norwegian Petroleum Industry

    Master-uppsats, Lunds universitet/Riskhantering (CI)

    Författare :Linnéa Tengvall; [2019]
    Nyckelord :Worst Credible Process Fire; Norwegian offshore industry; offshore fire safety; offshore process safety; offshore design; Technology and Engineering;

    Sammanfattning : The term Worst Credible Process Fire (WCPF) was introduced to the Norwegian Petroleum Industry as a complement to the probabilistic approach to define design loads for offshore facilities. Currently there are mainly two documents about the WCPF being the SINTEF report (2017) and the definition in NORSOK S-001 (2018). LÄS MER

  5. 5. A Machine Learning Approach to Predictively Determine Filter Clogging in a Ballast Water Treatment System

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

    Författare :Kristoffer Sliwinski; [2019]
    Nyckelord :;

    Sammanfattning : Since the introduction of the Ballast Water Management Convention, ballast water treatment systems are required to be used on ships for processing the ballast water to avoid spreading bacteria or other microbes which can destroy foreign ecosystems. One way of pre-processing the water for treatment is by straining the water through a filtration unit. LÄS MER
