3. 2. Evaluation of Excess Heat Driven Carbon Capture Integrated at a Swedish Pulp Mill

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Frida Nilsson; [2023]
   Keywords : CCS; BECCS; pulp and paper industry; pulp mill; excess heat; MEA; HPC; AMP; DMSO; chemical engineering; environmental engineering; Technology and Engineering;

   Abstract : As the atmospheric carbon dioxide keeps increasing, bioenergy with carbon capture and storage (BECCS) is getting increased attention as a measure to reduce the emissions of carbon dioxide. It is especially interesting in Sweden where the extensive paper and pulp industry constitutes point sources of biogenic carbon dioxide. READ MORE

4. 3. Automated High-Temperature Pressure Sensor Verification and Characterization

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Algirdas Bartkevicius; [2023]
   Keywords : Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

   Abstract : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. READ MORE

5. 4. Pre-study for SMR and Nuclear Establishment in Norway

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Johan Stefan Nordström; [2023]
   Keywords : Energy mapping; Nuclear power; SMR; small modular reactors; siting; Norway; Energy; Technology and Engineering;

   Abstract : Norway has Europe’s highest share of renewable electricity production and the lowest power sector emissions. Thanks to the country’s stable power production, Norway has affordable and stable access to electricity, leading to industries choosing to relocate to the country. READ MORE

6. 5. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
   Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

   Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE
