1. 6. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

   Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Tanmmay Rout; [2023]
   Nyckelord :Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

   Sammanfattning : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

3. 7. Process and techno-economic analysis of a compact CO2 capture technology

   Master-uppsats, KTH/Energiprocesser

   Författare :Nestor Salvador Palacios; [2023]
   Nyckelord :Carbon capture; CO2 capture cost; compact system; packed column; potassium carbonate; Kolavskiljning; CO2 fångskostnad; kompakt system; packad kolonn; kaliumkarbonat;

   Sammanfattning : Den stora oron för de ökade växthusutsläppen och klimatförändringas effekter har uppmuntrat utvecklingen av åtgärder för att motverka de negativa konsekvenserna. En av de tekniker som har uppmärksammats under de senaste decennierna är kolavskiljningstekniken. LÄS MER

4. 8. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Anna Wagne; [2023]
   Nyckelord :Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

   Sammanfattning : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. LÄS MER

5. 9. Carbon Capture for Biomass Combustion

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Anders Amundsson; [2023]
   Nyckelord :beccs; ccs; carbon capture; AMP DMSO; amine absorption; heat integration; chemical engineering; environmental engineering; Technology and Engineering;

   Sammanfattning : In order to limit global warming, bioenergy carbon capture and storage (BECCS) technologies are getting increased attention. To meet emission scenarios, an estimated 4000 carbon capture plants are expected to be required by 2030, indicating that progress in carbon capture and storage (CCS) deployment is currently lagging behind expectation.

7. 10. Operating procedures and evaluation of a carbon capture pilot plant

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Isac Logeke; [2023]
   Nyckelord :Carbon Capture and Storage; CCS; AMP DMSO; amine absorption; pilot plant; operating procedures; chemical engineering; Chemistry;

   Sammanfattning : The rise in global emissions of carbon dioxide and the need for new technologies to combat climate change has prompted extensive research into carbon capture methods. This master thesis focuses on a novel carbon capture absorption technology, developed at Lund University, that utilizes the amine 2-amino-2-methyl-1-propanol (AMP) in the organic solvent dimethyl sulfoxide (DMSO) to capture CO2.
