The Capture and Sequestration of Carbon Dioxide

bullet1 The Technology for Capturing Carbon Dioxide
bullet2 Technologies

bullet3 Pre-combustion (Hydrogen)

Coal-fired power plant (IGCC) Pre-combustion


Advantages

    • Generally higher CO2 concentration than for post-combustion capture
    • No need for powerful solvent
    • Higher pressure
      • More compact equipment
      • Higher driving force for CO2 separation

Disadvantages

    • Fuel processing is needed
      • Partially oxidation
        • Needed anyway for coal and oil to remove impurities
      • Shift conversion of fuel gas to H2 and CO2
    • Involve more radical change in power plants design
