CO2 Capture

← Previous | Next →

The CO2 Capture menu allows you to choose the CO2 capture system, one of the following:

•None: (This is the default.) No CO2 capture is used.

•Sour Shift + Selexol: A CO2 capture system is used, which consists of gas shift reactors and a Selexol-based CO2 removal system. This option requires Selexol Sulfur Removal. See Water Gas Shift Reactor Parameters, Selexol CO2 Capture Parameters, Water Gas Shift ReactorResults, and Selexol CO2 Capture Results for more details..

•Chemical Looping: In the Chemical Looping Combustion process, fuel is combusted with the aid of an Oxygen Carrier rather than through direct contact with air. The products of combustion include only water and CO2, allowing a very high purity CO2 stream to be obtained by condensing the water vapor. See Chemical Looping Parameters , Chemical Looping Results, and Purification Unit Results for more details.

•Sour Shift + Ionic Liquid: A CO2 capture system is used, which consists of gas shift reactors and an ionic liquid-based CO2 removal system. See Water Gas Shift Reactor Parameters, Ionic Liquid CO2 Capture Parameters , Water Gas Shift ReactorResults , and Ionic Liquid CO2 Capture Results for more details.
