Abstract
The method of simultaneously reducing carbon dioxide (CO ) emissions and sulfur dioxide (SO ) emissions produced by the combustion of carbon-containing matter in a hearth consists in injecting into the hearth a calcium-based agent, a fraction of which absorbs SO after decarbonization, and then, after the flue gases have been subjected to intermediate cooling, in causing them to transit via a first reactor and in putting them in contact therein with the other fraction of the absorbant that has not reacted with SO so as to capture CO from the flue gases by carbonization, then, in a separator, in extracting the solids contained in the flue gases output from the first reactor so as to subject them to heat treatment in a second reactor in order to extract CO therefrom by decarbonization and in order to recycle the resulting regenerated CO absorbant to the first reactor.
