METHOD FOR BURNING CARBONATED FUELS WITH COMBUSTION SMOKE FILTRATION BEFORE COMPRESSION

摘要

The invention relates to a method for burning carbonated fuels, that uses a combustion unit generating combustion fumes also containing carbon dioxide (CO2), solid particles and at least one impurity selected from H2O, N2, O2, Ar, NOx and SOx, characterised in that it comprises the following steps: a) filtration of the combustion fumes in order to reach a solid-particle concentration lower than 1mg/m3; b) compression of the combustion fumes filtered in step a); c) purification of the combustion fumes compressed in step b) in order at least partially remove one of the impurities; and d) recovery of a CO2-enriched gas flow.
