   Sammanfattning : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. LÄS MER

4. 18. EFFEKTIVISERING AV ENERGIANVÄNDNING FÖR MARKVÄRME MED HJÄLP AV VÄDERPROGNOSER

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

   Författare :Niklas Dalberg; [2023]
   Nyckelord :markvärme; driftstyrning; energiförbrukning; väderprognoser; marktemperatur; markvärmesystem;

   Sammanfattning : Markvärme används för att hålla bland annat gångvägar och parkeringshus fria från snö och is. Dessa system styrs oftast baserat på momentan data hämtat direkt från anläggningen. LÄS MER

5. 19. Mapping and analysis of an internal heating network at Holmen Paper Braviken

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Ludwig Forsell; Ebba Samuelsson; [2023]
   Nyckelord :Energy mapping; Holmen paper Braviken; Internal heating network; Holmen; Energy usage in the paper industry; Energy usage for a TMP-plant;

   Sammanfattning : The pulp and paper industry is the most energy intensive industry in Sweden. Most of the energy usedaims to supply the large amount of heat to the production processes that is required to produce pulp andpaper . LÄS MER

7. 20. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Douglas Björkengren; [2023]
   Nyckelord :polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Sammanfattning : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.
