11. Precipitating Amine Absorption Systems for Carbon Capture
Sammanfattning : Carbon capture using amine-based absorption is an established technology for the separation of gaseous CO2. It is used in the upgrading of gaseous fuels, and it has also been suggested that it could play a crucial role in the mitigation of climate change through post-combustion carbon capture and sequestration (CCS), and by creating carbon sinks through bioenergy CCS.

12. Opportunities for CO2 Reductions and CO2-Lean Energy Systems in Pulp and Paper Mills
Sammanfattning : The risk for climate change is a growing concern for theglobal society. According to what is known as the Kyoto Protocol,developed countries have committed themselves to reduce theirgreenhouse gas (GHG) emissions. The purpose of this thesis hasbeen to analyse opportunities for CO2 reductions in Swedish pulpand paper mills. LÄS MER
13. A Thermoeconomic Evaluation of CO2 Capture with Focus on Gas Turbine-Based Power Plants
Sammanfattning : The increasing emissions of carbon dioxide from fossil fuel burning are today thought to be one of the main contributors to global warming. At the same time, developing countries are striving for an increased welfare and burning more fossil fuel, which in turn is augmenting the greenhouse gas effect. LÄS MER
14. Capture of CO2 from solid fuels using Chemical-Looping Combustion and Chemical-Looping Oxygen Uncoupling
Sammanfattning : In order to meet the global demand of CO2 neutral energy, chemical-looping combustion could play an important role. Oxygen can be transferred from the combustion air to the fuel by means of oxygen carrying metal oxide particles circulating between two reactors, an air- and a fuel reactor. LÄS MER
15. Design and Optimization of CO2 sorbents for Point Source Emissions and Direct Air Capture
Sammanfattning : This thesis presents a comprehensive study on the design and optimization of CO2 sorbents, targeting two distinct applications: CO2 capture from point source emissions and Direct Air Capture (DAC). The research first introduces Na2HfO3 as a potential CO2 sorbent for point source emissions, using the molten salt effects of Na2CO3 and the thermal stability of HfO2. LÄS MER
