  1. 21. 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

  2. 22. Svavelcirkulation i cementprocessen längs ugnslinje 7

    Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Simanjit Singh; Lovisa Rova; Jennifer Andersson; [2020]
    Nyckelord :Cement; Svavel; cyklontorn; Svavelbalans; Påbakningar;

    Sammanfattning : Cement is produced in three main steps: grinding of a mixture of raw materials, sintering of the raw meal to form clinker, and grinding and mixing of clinker, gypsum and additives to make cement. Slag from steel manufacturing can be used to replace some of the raw material, but since slag is a carrier of some unwanted compounds, problems arise. LÄS MER

  3. 23. 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. 24. Worst Credible Process Fire: Experiences from the Norwegian Petroleum Industry

    Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    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. 25. 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
