1. 16. CO2 capture from oxy-fuel combustion power plants

   Författare :Yukun Hu; Jinyue Yan; Erik Dahlquist; Mats Westermark; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; oxy-fuel combustion; flue gas recycle; evaporative gas turbine; techno- economic evaluation;

   Sammanfattning : To mitigate the global greenhouse gases (GHGs) emissions, carbon dioxide (CO2) capture and storage (CCS) has the potential to play a significant role for reaching mitigation target. Oxy-fuel combustion is a promising technology for CO2 capture in power plants. LÄS MER

3. 17. Evaluation, Experience and Potential of Gas Turbine Based Cycles with Humidification

   Författare :Torbjörn Lindquist; Kraftverksteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Validation; Recuperator; Flue Gas Condensation; Humidification; Gas Turbine; Advanced Thermodynamic Cycles; HAT; Humid Air Turbine; Evaporative Gas Turbine Cycle; EvGT; Operating Experience; EvGT Pilot Plant; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

   Sammanfattning : Gas turbines, in simple and combined cycle, are common and economically profitable on the power generating market today. Several new cycles have been proposed as future competing technologies, but all studies about these cycles have, so far, been paperwork. LÄS MER

4. 18. SiC-FET Gas Sensors Developed for Control of the Flue Gas Desulfurization System in Power Plants Experimental and Modeling : Experimental and Modeling

   Författare :Zhafira Darmastuti; Anita Lloyd Spetz; Lars Ojamäe; Niclas Lindqvist; Mike Andersson; Bilge Saruhan-Brings; Linköpings universitet; []
   Nyckelord :SiC-FET sensors; temperature cycle operation; detection mechanism studies; SO2; H2S;

   Sammanfattning : Electricity and power generation is an essential part of our life. However, powergeneration activities also create by-products (such as sulphur oxides, nitrogen oxides,carbon monoxide, etc), which can be dangerous when released to the atmosphere. LÄS MER

5. 19. Narrow-pore zeolites and zeolite-like adsorbents for CO2 separation

   Författare :Ocean Cheung; Niklas Hedin; Paul A. Wright; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CO2 separation; zeolites; phosphates; titanium silicates; ion exchange; flue gas CO2 capture; biogas upgrading; Materials Chemistry; materialkemi;

   Sammanfattning : A range of porous solid adsorbents were synthesised and their ability to separate and capture carbon dioxide (CO2) from gas mixtures was examined. CO2 separation from flue gas – a type of exhaust gas from fossil fuel combustion that consists of CO2 mixed with mainly nitrogen and biogas (consists of CO2 mixed with mainly methane) were explicitly considered.

7. 20. Oxy-coal combustion and its integration with power systems for CO2 capture

   Författare :Yukun Hu; Jinyue Yan; Roland Span; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxy-coal combustion; flue gas recycle; radiation; peak and off-peak operations; cryogenic CO2 purification;

   Sammanfattning : Oxy-fuel combustion is one of the technologies for carbon dioxide (CO2) capture and storage (CCS) in fossil fuel based power systems to mitigate global greenhouse gases (GHGs) emissions. When introducing oxy-fuel combustion into the power systems, energy penalty for CCS has significant impacts on the system performance. LÄS MER
