1. 1. Technical and Economic Conditions for Efficient Implementation of CO2 Capture - process design and operational strategies for power generation and process industries

   Författare :Stefanìa Òsk Gardarsdòttir; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-combustion; CCS; chemical absorption; dynamic modeling; industrial sources; CO2 capture and storage; variable electricity generation;

   Sammanfattning : This thesis investigates the operational parameters of fossil-based power generation and industrial processes in future energy systems that have stringent constraints on CO2 emissions, and, consequently, large shares of renewable energy. CO2 capture and storage, which is the focus of this work, is required for power and industrial processes that emit CO2. LÄS MER

3. 2. Modeling of post-combustion carbon capture in power plants and process industries - partial capture and load following conditions

   Författare :Stefanìa Òsk Gardarsdòttir; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-combustion; MEA; ammonia; dynamic modelling; chemical absorption; industrial sources;

   Sammanfattning : Carbon capture and storage (CCS) is recognized as a potent technology for the mitigation of global warming, since it can significantly reduce CO2 emission from large point source emitters. Post-combustion CO2 capture using chemical absorption is a versatile end-of-pipe technology that can be implemented at all point sources of CO2, such as a power production facility or industrial plant.

   Sammanfattning : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. LÄS MER

5. 4. System studies of different CO2 mitigation options in the oil refining industry: Post-combustion CO2 capture and biomass gasification

   Författare :Daniella Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; post-combustion CO2 capture. CO2 capture and storage CCS ; GHG emissions; oil refining industry; CO2 emissions; Fischer-Tropsch FT ; biomass gasification; energy market scenarios;

   Sammanfattning : To reach the objective endorsed by the EU Council for reducing EU greenhouse gas (GHG) emissions by 80-90% compared to 1990 levels by 2050, extensive cuts are necessary in all sectors. The oil refining sector is a major energy user and thus a major GHG emitter. LÄS MER

7. 5. Reducing Carbon Emissions From Natural Gas-fired Power Plants – Biomass, Concentrated Solar and Carbon Capture

   Författare :Erik Pihl; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon capture and storage; bioenergy; biofuels; optimisation; modeling; solar thermal power; resource limitations; thermo-economic assessment;

   Sammanfattning : In this thesis, possibilities to reduce emissions from combined cycle gas turbine (CCGT) plants are evaluated. The evaluation is done from two perspectives: techno-economic analysis, and analysis of the resource and integration potentials. LÄS MER
