Abstract
The invention relates to a method for decreasing the level of carbon dioxide present in the fumes discharged by a power generator burning a mixture of a combustive agent and of a fuel containing hydrocarbons, wherein a gaseous mixture comprising at least part of said combustive agent and at least part of said fumes is compressed, all or part of the carbon dioxide present in the compressed gaseous mixture is eliminated by absorption, a fuel is mixed with the gaseous mixture, the resulting mixture of fuel and gaseous mixture is burnt and the fumes from the combustion process are expanded. The invention also relates to a power generator for implementing said method.
Claims16
1) A method for decreasing the level of carbon dioxide (CO2) present in the fumes discharged by a power generator burning a mixture of a combustive agent and of a fuel containing hydrocarbons, characterized in that it comprises at least the following stages:
- a) compressing a gaseous mixture containing at least part of said combustive agent and at least part of said fumes,
- b) eliminating by absorption all or part of the CO2 present in the compressed gaseous mixture,
- c) mixing a fuel with the gaseous mixture and burning the resulting mixture of fuel and gaseous mixture,
- d) expanding the fumes from the combustion process.
10) A power generator burning a mixture of a combustive agent and of a fuel containing hydrocarbons and including at least one compressor (2;
- 15, 17) with at least one compression stage, at least one combustion means (9) and at least one expander (3), characterized in that it comprises carbon dioxide absorption means (11) arranged upstream from combustion means (9) in relation to the direction of circulation of the fumes.
