Postcombustion carbon capture

The IGCC plant is a means of using coal and steam to produce hydrogen and carbon monoxide (CO) from the coal and these are then burned in a gas turbine with secondary steam turbine (i.e., combined cycle) to produce electricity. If the IGCC gasifier is fed with oxygen rather than air, the flue gas contains highly concentrated CO2 which can readily be captured postcombustion as seen earlier.

While carbon dioxide capture technologies are new to the power industry, they have been deployed for the past 60 years by the oil, gas, and chemical industries. They are an integral component of natural gas processing and of many coal gasification processes used for the production of syngas, chemicals, and liquid fuels. There are three main carbon dioxide capture processes for power generation (1) postcombustion, (2) precombustion, and (3) oxyfuel.

The capture and geological storage of carbon dioxide is one of the routes to provide carbon-lean electricity and is seen as a technology that may bridge the gap between the current C02-intensive electricity production and a future where renewable sources provide the bulk of the electricity (40). For the power generation sector, several options are in development for the capture of CO2. Postcombustion CO2 capture removes the CO2 from the flue gases of a power plant, using chemical solvents. Alternatively, combustion of coal or natural gas can be carried out...
