21. High Resolution 3D Printing with Cellulose Acetate
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella materialSammanfattning : 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
22. Svavelcirkulation i cementprocessen längs ugnslinje 7
Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - ÅngströmSammanfattning : 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
23. Theoretical and Experimental Characterizationof a Soft Polymer Heat Exchanger forWastewater Heat Recovery
Master-uppsats, KTH/EnergiteknikSammanfattning : 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.

24. Worst Credible Process Fire: Experiences from the Norwegian Petroleum Industry
Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och SamhällssäkerhetSammanfattning : 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
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)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
