An Introduction to CO2 Separation and Capture Technologies

eliminate separate control steps and sequester the NO x and SO 2 along with the CO 2, resulting in a zero emissions power plant. 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 watergas shift, where the CO is reacted with steam to form CO 2 and H 2. The CO ...
