Abstract
A process for the combustion of a carbon-containing fuel, wherein the flue gases are filtered so as to achieve a solid particle concentration of less than 1 mg/m3 before compression, purification and sequestration or transport is presented.
Claims13
A process for treating flue gases comprising carbon dioxide, solid particles and at least one impurity selected from the group consisting of:
- water, nitrogen, oxygen, argon, nitrogen oxides, and sulfur oxides, said process comprising:
- a) filtrating the flue gases, thereby achieving a solid particle concentration of less than 100 μg/m3., wherein the filtration is carried out using a cartridge filter, wherein the cartridge filter is declogged using a CO2 rich fluid;
- b) compressing the flue gases filtered at step a);
- c) purifying the flue gases compressed at step b), thereby at least partly eliminating at least one of the impurities;
- and
- d) recovering a CO2-enriched gas stream.
