Conventional Coal-Fired Power Plant an overview

A conventional coal-fired power plant with post-combustion capture has to separate carbon dioxide from a flue gas mixture in which there is a large amount of nitrogen. The oxyfuel process, by removing the nitrogen at the start, so that coal burns in oxygen instead of air, sidesteps this problem because the flue gases from the combustion process are largely carbon dioxide.
