An Introduction to CO2 Separation and Capture

2021-1-6  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 water-gas shift, where the CO ...
