A gas purification system (40) for cleaning a carbon dioxide rich flue gas generated in a boiler combusting a fuel in the presence of a gas containing oxygen gas comprises:
a compressor (40') for compressing the carbon dioxide rich flue gas,
a first gas cooler (64) for cooling the compressed carbon dioxide rich flue gas,
a mercury adsorber (66) arranged downstream of the first gas cooler (64) for removing at least a portion of a mercury content of the cooled compressed carbon dioxide rich flue gas,
a second gas cooler (68) arranged downstream of the mercury adsorber (66) for further cooling the compressed carbon dioxide rich flue gas, and
a gas drier (70) for removing at least a portion of a water content of the further cooled compressed carbon dioxide rich flue gas. |
