Gasification process
In an IGCC (Integrated Gasification Combined Cycle) power plant, fuel in some form is gasified in the presence of oxygen at high pressures. A typical temperature would be about 1316°C (2400°F) and a typical pressure range would be between 13.8 and 41.4 barg (200-600 psig).
The concept is to only partially oxidize the fuels to produce syngas. Syngas is usually composed of CO, CO2, H2 and water.
Syngas has a heat value and is passed through a heat recovery unit, which uses the heat to convert water to steam. The syngas is further combusted in a gas turbine resulting in a flue gas composed of CO2, H2O, and O2. The flue gas is sent to the absorber where the CO2 is absorbed by one of the following solvents:
Catacarb.
