    An Introduction To Co2 Separation And Capture

    An Introduction to CO2 Separation and Capture.Integrated coal gasification combined cycle IGCC plants are an example of the hydrogen route. Coal is gasified to form synthesis gas syngas of CO and H 2. The gas then undergoes the water-gas shift, where the CO is reacted with steam to form CO 2 and H 2. The CO 2 is then removed, with the hydrogen being sent to a gas turbine combined cycle.
