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

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

   Sammanfattning : 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. LÄS MER

3. 2. Geobacillus 7349 – A new potential biosurfactant producing microorganism

   Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Författare :Zhuoying Deng; [2023]
   Nyckelord :biosurfactant; rhamnolipids; HPLC; HPAEC-PAD; bacteria growth; downstream purification; liquid-liquid extraction; biotechnology; Chemistry;

   Sammanfattning : The main aim of this master project is to find out whether strain Geobacillus 7349 can produce biosurfactant during their growth by extraction and characterization of the product. The other goal is to optimize the cultivation condition of the strain. LÄS MER

4. 3. CFD investigation of a unit cell inside a Plate Heat Exchanger

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Mattias Ly; [2023]
   Nyckelord :Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

   Sammanfattning : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. LÄS MER

5. 4. A Techno-Economic Case Study of the Implementation of Hydrogen Technology in Connection to a CHP Plant

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Kristina Häggström Wedding; Amanda Kander; [2023]
   Nyckelord :Hydrogen Technology; Electrolyzer; Fuel Cell; Ancillary Services; Electricity Markets; Power Balancing; Balancing Markets; Power to Gas; Power to Power; Combined Heat and Power; District Heat; Heat Utilization; Flexibility; Optimization; Technology and Engineering;

   Sammanfattning : With climate change as the main driving force, the energy system is currently undergoing changes. Both the share of renewable resources used to produce electricity and the overall electrification is increasing. A way to handle the resulting challenges from more intermittent electricity production is by the implementation hydrogen technology. LÄS MER

7. 5. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate

   L3-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
   Nyckelord :GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

   Sammanfattning : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients.  This project is part of a greater project that is divided in two with different focus areas. LÄS MER
