  1. 16. Carbon dioxide de-airing in cardiac surgery

    Författare :Peter Svenarud; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Carbon dioxide; De-airing; Air embolism; Cardiac surgery; Insufflation device; Microemboli; Transesophageal echocardiography;

    Sammanfattning : Background: The risks connected with the presence of air microemboli in open-heart surgery, have recently been emphasized by reports that their number is correlated with the degree of postoperative neuropsychological disorder. Insufflation of carbon dioxide (C02) into the chest wound is used in open-heart surgery to de-air the heart and great vessels. LÄS MER

  2. 17. Ammonia as an Absorbent of Carbon Dioxide in Post-Combustion Capture - an Experimental, Technical and Economic Process Evaluation

    Författare :Henrik Jilvero; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost of capture; carbon dioxide; carbon capture; power plant; ammonia; process simulations;

    Sammanfattning : Carbon capture and storage is vital to facilitating the transition from our current fossil fuel-based energy system to a sustainable energy system. The concept of post-combustion capture is based on the selective chemical absorption of carbon dioxide (CO2). LÄS MER

  4. 19. Reducing Carbon Dioxide Emissions from the EU Power and Industry Sectors - An assessment of key technologies and measures

    Författare :Johan Rootzén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industry; carbon dioxide; cement; European Union; technologies; emission reductions; CCS; power; steel; CO2< sub>; refining; mitigation;

    Sammanfattning : In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80% by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. LÄS MER

  5. 20. Assessing Carbon Dioxide Removal methods amid uncertainty : soil carbon sequestration, biochar and harvested wood products as methods for climate change mitigation

    Författare :Alexander Olsson; Stefan Grönkvist; Mathias Fridahl; Anders Hansson; Lowe Börjeson; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Removal CDR ; Negative Emissions Technologies NETs ; Soil Organic Carbon; Biochar; Harvested Wood Products HWP ; Socio-technical systems; Strategic Niche Management SNM ; Chemical Engineering; Kemiteknik;

    Sammanfattning : Measures to sequester carbon dioxide (CO2) away from the atmosphere have become increasingly important in the discussion of which methods humans can employ to limit global warming. These measures, which are broad and varied, fall under the umbrella of Carbon Dioxide Removal (CDR) methods. LÄS MER
