Abstract:
1. A method of cleaning a carbon dioxide rich flue gas generated in a boiler combusting a fuel in the presence of a gas containing oxygen gas, the method comprising compressing the carbon dioxide rich flue gas, cooling the compressed carbon dioxide rich flue gas to a first temperature that is higher than a dew point temperature with respect to water vapour of the compressed carbon dioxide rich flue gas, forwarding the cooled compressed carbon dioxide rich flue gas through a mercury adsorber to remove at least a portion of a mercury content of the cooled compressed carbon dioxide rich flue gas, further cooling the cooled compressed carbon dioxide rich flue gas to a second temperature, which is lower than the first temperature, and forwarding the further cooled compressed carbon dioxide rich flue gas through a drier to remove at least a portion of a water content of the further cooled compressed carbon dioxide rich flue gas.
