TYPES OF CAPTURE

1 PRECOMBUSTION

Before combustion, fossil fuels are separated into a gaseous mixture of carbon dioxide and hydrogen. The hydrogen can be burned, while the CO2 is compressed and stored.

2 POST-COMBUSTION2

This is the capture of CO from the exhaust gas after the fuel has been burned. A liquid solvent can absorb the CO2 from the captured exhaust gas, preventing it from entering the atmosphere.

3 OXYFUEL

Combustion takes place in pure oxygen so that the exhaust gases are cleaner, consisting mainly of CO2 and water. This makes the CO2 easier to extract and capture.
